For our local 2m net, the Net Control Station asks a Question of the Night to stimulate some discussion. Recently, the question was:
Do you have any interest in CW. If yes, Do you currently operate CW or do you plan to learn? If you have no interest in CW, what other modes besides voice do you operate on or would like to?
I am not a huge CW fan, but I do use it from time to time, especially when it comes to squeezing out difficult contacts on VHF or UHF. However, this question had me thinking about the various modes I have operated, so I made a list:
SSB - quite often on HF, VHF, UHF
CW - not nearly as often but on HF, VHF, UHF
FM/PM - lots of VHF activity here, 2m FM is the Utility Mode
AM - a few times, just to check it out
RTTY - I used to do this often but my interest has faded
PSK31 - I used to do this often but my interest has faded
FT8 - this one has taken over my digital operating
FT4 - a faster alternative to FT8, often better to use
Q65 - I just started using this for weak-signal VHF/UHF
MSK144 - for meteor scatter, but I haven't done that for a while
AX.25 - VHF packet radio, including APRS
DMR - the most common digital mode in Colorado
D-STAR - I used D-STAR when it first came out but lost interest
C4FM - Yaesu Fusion, I've used it a few times
Each one of these modes has a story behind it…often I was just looking for something new to try. (If you find yourself getting bored with ham radio, it might be time to try a new mode.)
This list also reminds me that I need to get back to chasing grids on the 2-meter band, using CW, SSB, FT8, MSK144, and Q65. I have a new tower up that I’ve not taken full advantage of for VHF/UHF.
That’s my list of modes used, what does your list look like?
Recently, I’ve been getting questions about whether a ham needs to log radio contacts, whether they need to submit a log, and how to do it. Logging is a complex topic that can require a long and detailed explanation, but I am going to focus on the questions I’ve been hearing lately. I’ll also provide some links for further investigation. For starters, the ARRL has a good introduction to logging.
A paper ham radio log
Why Keep A Log?
The FCC does not require you to log your amateur radio contacts. Many radio amateurs, especially if they just operate casually on 2m and 70 cm, don’t bother to keep a log. Probably the most common reason for having a log is to have a record of your radio contacts, in terms of stations worked, on what band and what conditions. This might be just for your own personal satisfaction or you might want to keep track of these contacts so you can get credit for an award, such as the ARRL Worked All States (WAS) award.
Paper or Electronic?
The Old School way of keeping a log is on paper as shown in the figure above. This approach is simple and reliable technology but is quite limited in the information age. These days, most hams that record log information store it electronically. Imagine that you log thousands of contacts over time and then want to find a particular callsign or location. Much better to do this electronically. There are many good software programs available, too many to list here. I currently use Amateur Contact Log from N3FPJ. The good news is that there is a standard file format for storing and moving ham radio contact information: Amateur Data Interchange Format (ADIF). If you want to change logging software, you export an ADIF file and import into the new program.
I Worked a Contest Station, Do I Have to Submit a Log?
Sometimes radio ham works a few stations that are active in a particular contest and they wonder if they must submit a log to the contest sponsors so that these these stations get credit for the contacts. The almost universal answer to this is: No. Don’t worry about submitting a contest log if you aren’t really “in the contest.” The stations you work still get credit for your contact with them. (This is true for all major contests…I am still looking for a contest where this is not true.) Contests are designed to encourage activity, so they want everyone to join in, even if they aren’t all that serious about contesting. (The contest sponsors will appreciate any and all logs submitted, so consider that.)
If I Am Actively Working a Contest, What Do I Do?
If you are actively participating in a contest, you should use a logging program that is tuned for that particular contest. This is important because the contest logging software knows about the scoring for the contest and lets you know if you have already worked a station you hear. The most popular logging software for contesting is the N1MM Plus software. There are other programs you can consider. Typically, you would use N1MM during the contest and then export the info into an ADIF file, which is imported into your “main” logging program.
What is a Cabrillo File?
While the ADIF file format is most universal in ham radio logging, there is another file format used for contesting. This is the Cabrillo file format. Your contest logging software can generate a Cabrillo file for submitting to the contest sponsor. You may also want to generate an ADIF file to import into your normal logging program.
I Worked a POTA Station, Do I Have to Submit a Log?
Parks On The Air (POTA) is set up so that only the activator station submits a log. If you are working an activator station, you are a hunter station. The POTA scores are all based on the activator logs and hunters cannot submit a log. What you can do is register on the POTA website to see the contacts that the activators have submitted for you.
I Worked a SOTA Station, Do I Have to Submit a Log?
Summits On The Air (SOTA) is set up so that both activators and chasers submit logs to the SOTA website. However, the SOTA system operates on the honor system, so an activator can claim a contact with you without you submitting a log. So if you hear a SOTA station, go ahead and work them. You don’t have to submit a log. On the other hand, if you want credit for chasing a summit, you need to submit a log. So that activator is fine not having you submit a log but you may want to do that to get credit for you.
How Do I Get Credit For Working A Country?
The gold standard for chasing countries, I mean entities, is DX Century Club (DXCC). If you are interested in DX, you should register with Logbook of The World (LoTW) with the ARRL. To get credit for working an entity (country), you need to submit your log and it must match the log submitted by the DX station. This is a higher level of confirmation because both parties must submit the log info and it must match within reasonable error limits.
There are other award systems for working countries, offered by QRZ, eQSL, etc.
How Do I Get Credit For Working a Grid on VHF/UHF?
The VHF UHF Century Club (VUCC) is the VHF/UHF equivalent to DXCC. Here the emphasis is on working maidenhead gridlocators on the bands above 50 MHz. Again, Logbook of The World is the database that authenticates confirmed contacts on these bands. Both parties must submit the log info and it must match within reasonable error limits.
What If Someone Needs My Log Submitted?
Most of the time, us normal hams are not considered DX. That is, that other station in the Cayman Islands doesn’t really need our contact confirmed. But there are exceptions. You might be in a state the other station needs confirmed. Or maybe it’s your county they need. In such a case, you might want to make a special effort to provide your log information to the right database. It will depend on what the other station needs…if they are going for an ARRL award, then Logbook of The World is the right place to upload your log. But they might be after a QRZ award or eQSL award, in which case you would need to provide your log to those websites.
Wrap Up
These are some of the questions I’ve been hearing.
What did I miss?
Anything else to add?
Amateur Radio Fun in the Colorado Mountains
August 2 through 5, 2024 www.ham14er.org
Amateur Radio operators from around Colorado will be climbing ColoradoSummits On The Air (SOTA) peaks and communicating with other radio amateurs across the state and around the world. Join in the fun during the annual event by activating a summit or contacting (chasing) the mountaintop stations.
This event is normally held the first full weekend in August. Again this year, we will add two bonus days to the Colorado 14er Event. The main two days remain Saturday and Sunday (Aug 3 & 4), while the bonus days are Friday Aug 2nd and Monday Aug 5th, for those SOTA enthusiasts that need more than two days of SOTA fun! Be aware that many mountaintop activators will hit the trail early with the goal of being off the summits by (1800 UTC) noon due to lightning safety concerns.
The 14er event includes Summits On the Air (SOTA) peaks, which provide over 1700 summits to activate. (See the W0C SOTA web page or browse the SOTA Atlas.) The Colorado 14er Event was started in 1991, about 19 years before the SOTA program was set up in Colorado. As SOTA grew in popularity, this event expanded from just the 14,000-foot mountains (14ers) to include all of the SOTA summits in the state. We still call it the Colorado 14er Event because, well, that’s where it all started and the 14ers are the iconic summits in the state.
Important: The recommended 2m FM frequencies have been changed to 146.58, 146.55, and 146.49 MHz, to align with the use of the North America Adventure Frequency for SOTA (146.58). The National Simplex Calling Frequency (146.52) may be used as appropriate. There will be plenty of action on the other ham bands, for more information see the operating frequencies page.
Amateur radio transceivers have improved dramatically over the decades and they pack a lot of capability into relatively compact radios. In this post, we will take a look at the typical configurations and how they may impact setting up a flexible amateur radio station today. This discussion is focused on currently available new gear, with 50 to 100 watts of RF power.
The Kenwood TS-430S was a popular HF transceiver in the 1980s.
The most common HF radio configuration used to be a 5-band model that offered CW, AM, and SSB on 80 meters, 40 meters, 20 meters, 15 meters, and 10 meters. In the early 1980s, the WARC bands were added (named for the World Administrative Radio Conference of 1979) that authorized these new bands. The WARC bands are 30 meters, 17 meters, and 12 meters. These attractive new bands were soon added to the standard HF rig. Most HF radios include 160 meters (actually a Medium Frequency or MF band) on the low end and a general coverage receiver for 150 kHz to 30 MHz. So these days, the typical HF transceiver handles 9 bands and many different modes. (Actually, most of these rigs now include 6 meters, more on that later.)
Dominant Design
In the world of product development, the concept of a dominant design often emerges. This generally accepted approach dominates a particular market and is considered the standard way of doing things in a particular product category.
Dominant design is a technology management concept introduced by James M. Utterback and William J. Abernathy in 1975, identifying key technological features that become a de facto standard. A dominant design is the one that wins the allegiance of the marketplace, the one to which competitors and innovators must adhere if they hope to command significant market following.
We will see that most ham radio gear conforms to the concept of a dominant design. That is, certain product configurations become standard, especially in terms of frequency bands and modes. Manufacturers still innovate by adding new features in an attempt to differentiate and obtain competitive advantage but the basic capabilities are standard. The dominant design for HF transceivers is the 100-watt radio that covers 160m through 6m.
VHF/UHF Radios
For VHF/UHF, the situation is a bit more scattered. 2-meter FM is the most popular band and back in the olden days, it was common to just have a single-band 2m FM rig in the shack. To cover 70 cm FM, a radio ham needed a second radio but later dual-band radios showed up that covered 2m and 70 cm. Today, the dominant design for VHF/UHF is the dual-band FM transceiver (typically 50 watts of output power) and there are so many of these available I won’t attempt to list them.
The IC-2730A is a basic 2m and 70cm transceiver with dual receivers.
VHF FM is the utility mode for amateur radio and many hams are just fine using FM (or one of the digital voice modes) on VHF/UHF. Those who want to stretch the limits of VHF/UHF operating usually go for all-mode rigs that offer CW, SSB, FM and various WSJT digital modes. Again, back in the olden days, a VHF+ enthusiast would acquire single-band all-mode radios for the bands of interest. A ham really into VHF/UHF might have single-band radios for 6m, 2m, 1.25m, and 70 cm stacked up in the ham shack. The 1.25-meter band has always been a bit neglected in terms of equipment availability because that band is not available worldwide. Transverters are another option to get all-mode capability on these bands using an HF transceiver to transvert to a single VHF or UHF band.
HF Plus 6 Meters
One important addition to the standard HF rig is that the 6m band is often included. Now this may not sound quite right because we all know that 6 meters is a VHF band, so what is it doing in an HF radio? It actually makes a lot of sense because a lot of 6-meter operating is similar to HF. (6 meters is the VHF band that often emulates HF.) There is FM activity on 6 meters but most of the action is on SSB, CW, and, yes, FT8. In fact, FT8 is seeing a lot of action on the band, so if you want to participate on 6m, you should consider that mode. Anyway, this all means you probably need an all-mode radio for 6 meters, and having it as a bonus band on an HF radio without a huge increase in cost is a good approach. (These radios usually support FM for the 10m and 6m bands.)
The IC-7300 transceiver covers all the HF bands and 6 meters (50 MHz).
There are many great HF/6m radios to choose from so I won’t try to list them all. Some of the more popular ones in the $1k to $1.5k range are: Icom IC-7300, Yaesu FT-710, and Yaesu FT-DX10.
All-Band All-Mode Rigs
Another common transceiver configuration is the All-Band All-Mode radio available from several manufacturers. A great example of this type of radio is the Yaesu FT-991A, which includes 160m through 10m plus 6m, 2m, and 70cm. Once again, 1.25m is passed over. This radio configuration has a lot of appeal because it covers pretty much everything with all-mode capability. (It also has a built-in sound card and USB connection which is handy for the WSJT digital modes.)
The Yaesu FT-991A covers 160m through 10m, plus 6m, 2m and 70cm.
The FT-991A is a good choice for the ham shack or operating portable but it is a bit large for a mobile installation. Icom offers the IC-7100 in a mobile form factor, with a novel sloping detachable front panel. Yaesu used to offer mobile products in this space such as the very popular FT-857D transceiver. However, the FT-857D is no longer made and its apparent replacement is the FT-891 which has only the HF + 6m bands.
The Icom IC-7100 is a mobile rig with HF, 6m, 2m, and 70 cm.
The main disadvantage of this type of radio is that it can only do one frequency at a time. Often, I want to be able to work HF while still monitoring the local 2m FM repeater and simplex channels. Or maybe I’d like to keep listening for 6 meter activity while working 2m SSB, especially during a contest. However, this type of radio is my first choice for portable operating for Parks On The Air because it covers all the bands and modes. This article is focused on 100-watt radios but note that there are all-mode all-band QRP radios such as the IC-705.
All Mode VHF/UHF Radios
One interesting and disappointing trend that has emerged is the distinct lack of VHF/UHF all-mode transceivers. There is only one such radio on the market today, the Icom IC-9700 which does all modes on 2m, 70cm, and 23 cm (1.2 GHz). It seems that Icom decided that if they are going to offer a VHF/UHF radio, they would go full-featured and include 23 cm. Note that if you pair this radio with an HF plus 6m radio, you can cover all the popular bands with all modes using two radios. This radio is not inexpensive, currently selling new for about $1800.
The Icom IC-9700 is a VHF/UHF transceiver that offers all modes on 2m, 70cm and 23cm.
I suppose we can declare this the dominant design for VHF/UHF but it is a lone product in this space. I have written previously about an all-mode dual-band portable radio for 2m/70cm that I desire. I own an IC-9700 and like it a lot but I would give up the 23 cm band to have a radio that is more portable and less expensive. I suspect that Icom is happily making good profit margins on the IC-9700 given that they have essentially no competition in this space. Yaesu has the technology to do something here but has been content to let the FT-991A cover the all-mode 2m/70cm space for them.
Common Ham Shack Setups
Now let’s take a look at some common ham shack configurations that consider these different radio configurations. When I say “ham shack” that may include your mobile or portable station, too.
Setup 1: FM VHF/UHF Only A Technician might decide they want to focus on 2m and 70cm, with FM being just fine for working simplex and repeaters on those bands. A basic dual-band FM transceiver will handle this nicely, see A VHF FM Station at Home. For some hams, their dual-band handheld radio serves this purpose.
Setup 2: All-Band All-Mode Transceiver As mentioned earlier, All-Band All-Mode radios cover the most popular ham bands and modes with one rig. They are a good way to get one radio that does everything. The disadvantage is not being able to monitor VHF/UHF at the same time as working HF.
Setup 3: HF/6m radio plus 2m/70cm FM radio This is a very common configuration for a ham shack because it separates the HF bands (and 6m) from the 2m/70cm FM operating. The FM rig can be left monitoring your favorite repeater or simplex frequency while you chase DX on 15 meters. If your 2m/70cm needs are basic, the FM radio might even be a handheld transceiver.
Setup 4: HF/6m radio plus all-mode VHF/UHF radio This is the setup for the ham that wants to cover all the bands and be able to do all modes on VHF/UHF. The band/mode coverage is similar to Setup 2 but we have two radios available which provides the monitoring flexibility associated with Setup 3. This configuration allows for having a really good HF/6m radio and a really good VHF/UHF radio.
Conclusions
The ham radio transceivers being offered tend to follow certain patterns consistent with the dominant design theory. If you buy a modern HF transceiver, you will likely get all of the HF bands plus the 6m bonus band. These radios vary in features and performance but they all have good band/mode coverage. The VHF/UHF situation is perhaps not quite as simple. The standard 2m/70cm FM rig is a popular option but is limited to FM only. The VHF/UHF weak-signal enthusiast does not have many choices beyond the IC-9700, which may represent an opportunity for another manufacturer to jump in with a more cost-effective 2m/70cm all-mode radio. The 1.25m band continues to be neglected and may be a good additional band to add to 2m/70cm radios.
Pikes Peak is a great summit for a SOTA activation. You can hike up, drive up, or take the cog railway to get to the top. Pikes towers over eastern Colorado and has an excellent radio horizon in all directions. It is easy to work a bunch of stations on 2m FM. With a bit of effort, you can work Kansas, Nebraska, Wyoming, and New Mexico on VHF.
Fraser/MM0EFI was visiting from Scotland, operating here in the US as W0/M0EFI. Here’s his HF operating experience, with cameo appearances by Carey/KX0R, Christian/F4WBN, Elliot/K6EL, and Steve/WG0AT.
Now for the VHF fun on 2m FM. I happened to be on South Monarch Ridge (W0C/SP-058) that day and we completed a Summit-to-Summit contact on 146.52 MHz, at a distance of about 80 miles—easy contact using just HT’s on both ends.
Fraser, thanks for the fun videos from America’s Mountain.
When radio amateurs get ready to put an HF station on the air, they often have questions about what antenna to use. The good news is that there are many options to choose from. The bad news is that there are too many options to choose from. It can be overwhelming. This post describes an antenna I just installed that is easy to put up and works well.
The ponderosa pine tree supports the endfed wire antenna.
Having 30-foot tall pine trees on our property, my usual approach for HF antennas is “wires in the trees.” I have several ropes strung up over these tall trees so that I can raise and lower wire antennas as needed. These ropes were installed using a slingshot to launch a fishing line over the top of the tree, then I pulled up a lightweight rope.
The 9:1 UNUN provides the matching at the end of the wire antenna.
End Fed Long Wire
The antenna is the EFLW-1K from MyAntennas.com, which is an End Fed Long Wire Antenna. (This should not be confused with an End Fed Half Wave antenna.) This antenna is intentionally cut to not be a resonant length on any of the bands. The 9:1 UNUN transforms the high impedance at the end of the wire down to something closer to 50 ohms. The match is not perfect so an antenna tuner is required to cover all of the bands. MyAntennas offers this antenna with different lengths of wire, with longer wires required to support the lower HF bands. I purchased the 53-foot version but decided to shorten the wire. My interest is working 20 meters and higher and I wanted the antenna to be mostly vertical, so I shortened the wire to 36 feet. The MyAntennas products are good but other similar 9:1 UNUN products on the end of a wire will work.
An endfed antenna like this needs some kind of counterpoise to balance out the antenna operation. Many people have written about this and there are many different approaches. The MyAntenna UNUN has a connector intended to support adding a short length of counterpoise wire. I could have gone that route but a decent length of coaxial cable lying on the ground can function as this counterpoise. So that’s what I decided to use.
The B11ISO isolation transformer is inserted in line with the coaxial cable.
I also added an inline isolation transformer to minimize the common mode currents getting back to the transceiver. I don’t know that this is required but I had one available so I used it. The antenna has 50 feet of LMR 400 coax laying on the ground which connects to the inline transformer. Then, another 25 feet of RG-8X coax connects the transformer to my transceiver. The internal antenna tuner in my Icom IC-7610 handles this antenna quite well, tuning up on 20m, 17m, 15m, 12m and 10m. This means I can instantly switch between the bands and be ready to go.
I’ve been running SSB, FT8 and FT4 on this antenna, working many stations in all regions: Europe, Asia, Oceania, Africa, North and South America. Conditions are great and I keep telling newer folks: now is the time to be on HF! This basic antenna is a great way to get on the air and work some DX.
73 Bob K0NR
Update (18 Jan 2024): I gave this antenna a try on 6 meters using the IC-7610 (with tuner) and it works on that band, too.
Update (05 Feb 2024): Just for fun, I tried the antenna on 30m and 40m. I thought it would be too short but the tuner in the IC-7610 was happy and I am making contacts on those two bands.
The FCC will be voting on and will likely approve a Report and Order that eliminates the symbol rate restriction on HF data transmissions, replacing it with a bandwidth limit of 2.8 kHz. See FCC To Vote on Removing Symbol Rate Restrictions. The symbol rate limit of 300-baud is an obsolete way of limiting the signal bandwidth, created back when the data transmissions were predominately Frequency Shift Keying (FSK). It was a simple, practical way to regulate the bandwidth at that time but technology has moved on. The use of digital signal processing and efficient wireless encoding techniques require a better approach to bandwidth regulation.
A practical impact of this change is to allow higher speed protocols such as PACTOR-4 having a bandwidth of 2.4 kHz. I suspect we will see other protocols emerge that squeeze the best data rate out of the 2.8 kHz bandwidth.
Living in a Narrowband World
The FCC proposal implements a 2.8 kHz bandwidth limit on data emissions on the HF bands. Some folks have suggested a narrower bandwidth while others argue that wider bandwidth signals should be allowed. And some even think we should have no bandwidth limit at all.
The problem is that the amateur HF bands are not very wide. For example, the popular 20m band is 14.0 to 14.350 MHz, providing only 350 kHz of spectrum. Common practice on this and the other HF bands is to use modulation types that have bandwidths of 3 kHz or less. (Yeah, AM signals are twice that wide, at 6 KHz, a topic for another day.) Of course, CW and some of the data modes are much narrower than 3 kHz. But the general approach to regulating HF is to allow many narrowband signals on the band. Limiting HF data transmissions to 2.8 kHz bandwidth is consistent with existing practice while still allowing for innovation and experimentation.
VHF/UHF Bandwidth Limits
The FCC also plans to issue a Further Notice of Proposed Rulemaking (FNPR) that:
Proposes to remove the baud rate limitation in the 2200 meter and 630 meter bands, which the Commission allocated for amateur radio use after it released the Notice of Proposed Rulemaking in 2016.
Proposes to remove the baud rate limitation in the VHF and UHF bands.
Seeks comment on the appropriate bandwidth limitation for the 2200 meter band, the 630 meter band, and the VHF/UHF bands.
I won’t comment on the 2200 meter and 630 meter bands. The FCC proposes to remove the symbol rate limit on the VHF and UHF bands and asks what bandwidth limit is appropriate. The current bandwidth limits are 20 kHz for the 6m and 2m bands, 100 kHz for the 1.25m and 70 cm bands, and the FCC seems fine leaving these the same. Authorized emission types are listed in FCC Part 97.305.
With 4 MHz of spectrum, the 2m band is much wider than any of the HF bands. It might be tempting to conclude that there is plenty of room for wideband signals on this band. Many hams think 2 meters is just used for FM simplex and repeaters but a closer look reveals that it supports many diverse modes: weak-signal SSB/CW, meteor scatter, EME, FM simplex, FM repeaters, digital voice modes (D-STAR, DMR, Fusion), satellites, and more. The 20-kHz limit seems appropriate, as it roughly matches the bandwidth of the most common (FM) voice signals on that band. It is not an appropriate band for trying out wider bandwidth signals.
The 6m band should probably keep the same 20-kHz limit. (I don’t think there is a compelling reason to change it.) The 1.25m band already allows 100-kHz bandwidth data signals, which some radio amateurs have used for higher-speed data links (still not what I would call wideband).
The 70 cm band is much bigger (420 MHz to 450 MHz) and could accommodate some wider bandwidth signals. Perhaps the existing 100-kHz limit should be increased? Keep in mind that fast-scan ATV is allowed on this band with a bandwidth of 6 MHz. Maybe we can make some room for a few larger bandwidth data channels, to encourage innovation and experimentation.
The bands above 70 cm have no bandwidth limit other than the signal must stay within the designated ham band. It has been this way for a long time, without causing any issues (that I know of).
Conclusion
The FCC’s proposal makes a lot of sense and it is long overdue. Frankly, it is a bit of an embarrassment that it has taken so long.
A view of the W0C/RG-169 summit from the Continental Divide Trail. Look closely to see the game trail heading up to the right towards the saddle.
Lobo Overlook is an excellent summit and tourist spot near Wolf Creek Pass, one of the most scenic passes in Colorado. I’ve been up there for VHF contests and other mountaintop operations and initially thought it might be a SOTA summit. No such luck, as it is superseded by a higher summit nearby (W0C/RG-169). No problem, we’ll just activate that one instead. Lobo Overlook is accessed via an easy 3-mile gravel road just off the pass. The road leads to two small loops at the top, one of which is the actual Lobo Overlook while the other goes to an obvious radio site. The trail to RG-169 is best accessed from the radio site, so we parked there. Wolf Creek Pass and Lobo Overlook sit right on the Continental Divide and the Continental Divide Trail (CDT) passes through here just a bit to the west.
The Lobo Overlook road starts slightly east of Wolf Creek Pass.
Lobo Peak
This unnamed summit is listed as 11820 in the SOTA database. However, Lists of John (which was used to create the W0C SOTA database) shows this summit as 11831. My topo map seems to agree with 11831, so this might be an error. Of course, such a cool summit near the CDT deserves a name, so Joyce/K0JJW and I decided to call it Lobo Peak, for obvious reasons. (I looked for an existing nearby Lobo Peak and did not find one.)
Near the radio site, we started at the marked trailhead and headed west on Lobo Trail (878), actually going downhill to intersect the CDT about a half mile down the trail. At the trailhead, it was not obvious which summit we were headed to and it might not even be visible at that point. The summit did reveal itself as we headed down the CDT (see first photo above). We followed the CDT to a visible game trail that takes off steeply to the right (lat/lon 37.49765, -106.81515). There are several game trails that split off, heading up towards the saddle to the left of the summit and we stayed on the most established one. We set up our station within the activation zone just below the actual summit, avoiding the rock scrambling to get to the top.
The trail from Lobo Overlook to RG-169 mostly follows the Continental Divide Trail.
The one-way distance on the trail is 1.2 miles with an up-and-down profile. Lobo Overlook is only slightly lower in elevation from “Lobo Peak”. The trail starts at about 11,770 feet, descending to a low point of 11,500 and back up to 11,800 at the summit. So that produces a net ascent of about 300 feet, maybe more, one way. Of course, you get to repeat this on the way back.
The sign at the trailhead calls this Lobo Pass.
SOTA and POTA Activations
Once in the activation zone, we deployed the IC-705 on 2m FM, driving the 3-element Yagi antenna. We worked Travis/KB9LMJ on 146.52 MHz, who was mobile in Pagosa Springs. Further calling on 2m FM did not yield any contacts, but K0JJW and I did work each other on VHF/UHF. We had anticipated that this might be a tough place to activate on VHF, so we brought along the HF gear and set up an EndFed Halfwave antenna for 20m. Propagation was good and we soon worked 11 stations on 20m SSB.
This summit sits right on the dividing line between the Rio Grande National Forest and the San Juan National Forest, both valid for Parks On The Air (POTA). We opted to operate from the Rio Grande side (K-4405) because that was a new one for both of us.
This is the radio site as seen when you return from the summit, so no excuse for getting lost.
Continental Divide Trail
I’ve hiked sections of the Continental Divide Trail before, including some pre-SOTA backpack trips with Denny/KB9DPF. It is a great trail because it runs along the backbone of the Rocky Mountains. It is often accessible via roads to high mountain passes. (Another example is Wander Ridge, just off Cottonwood Pass.) Once you hop onto the CDT, you are hiking an established trail that is literally on top of the world.
This is an excellent, easy-to-access summit in the Wolf Creek Pass area. So if you are in the area, this might be one to activate. The road to Lobo Overlook is closed during the winter.
The FT8 station consists of an iPad, Icom IC-705, MFJ-902 tuner, a battery pack, and one of many wire antennas.
In a previous post, I described getting the IC-705 set up for FT8 using the SDR-Control app on an iPad. My objective was to have a portable FT8 station for use during SOTA and POTA activations.
To save time, let me get this out of the way:
Yes, I do know that making contacts via FT8 is not as personal and may not be as much fun as running a pileup on SSB or CW. Still, it is Real Ham Radio and enjoyable in a different way.
I’ve used this station on multiple activations now but I have to admit that these have been mostly for POTA. It seems that whenever I get on top of a SOTA summit, I tend to focus on making VHF contacts which consumes the available time and the HF gear remains stashed way in my pack. This is more about my operating habits than anything else. Looking at spots though, there is a lot of FT8 on POTA and not nearly as much on SOTA. The SOTA crowd tends to have a lot of traditional CW enthusiasts and maybe POTA has fewer of them. Also, SOTA operating is usually backpack portable so carrying a compute device for FT8 may be considered an unnecessary hassle. POTA stations are often in or near a vehicle, so station size/weight is less of a concern.
For POTA, I make sure my activation is posted at pota.app, indicating the park number I am activating. When calling CQ, I modify the standard FT8 text to be “CQ POTA” to indicate that I am doing an activation. When my signal is detected by the Reverse Beacon Network (RBN), a spot is created that shows me doing a POTA activation from that park. Pretty cool. If I have an internet connection, I monitor my spots using the Ham Alert app. This provides useful feedback about where my signal is showing up around the world.
But what are the main reasons that FT8 is useful for POTA?
FT8 is popular
In case you haven’t noticed, FT8 has emerged from being just a niche activity to now being very popular on most ham bands. At times this can be a problem with the standard FT8 frequency slice being overloaded with signals. There is a lot of FT8 activity on the bands, for general ham use and SOTA/POTA.
FT8 works well with low power
FT8 and the other WSJT-X modes are designed to work well with weak signals, so they are a great match for low-power operation. Of course, QRP power levels are very common for backpack portable activations, mostly due to the limitations of carrying a reasonable-size battery.
FT8 signals are spotted on RBN
As mentioned earlier, FT8 signals are picked up and spotted by RBN. For better or worse, people have come to rely on spotting for many types of ham radio operating. When on a SOTA or POTA activation, you really want to be spotted as such. For phone activations, I usually do that with a smartphone but that requires some extra effort and a mobile phone connection. FT8 and RBN take care of that for you.
FT8 logging is automated
The various FT8 software applications automatically log the QSO information, which means it is easy and less error-prone. After the activation, I just pull up the ADIF log file, check it for obvious errors, add in the SOTA/POTA info, and submit it to the appropriate websites.
FT8 is campsite friendly
This last one may be a bit subtle but I’ve found FT8 to be campsite friendly. By that, I mean I can get on the air at any time (early, late or at nap time) and not disturb anyone else. (On SSB, I would likely be enthusiastically yelling into the microphone trying to work a pileup.) Besides the audio noise factor, FT8 operation allows for multitasking. I can converse with my fellow campers while still keeping up with the FT8 flow. Alternatively, I can cook dinner, make a fire, or pack my backpack while the FT8 QSOs roll in. This may sound a little bit like cheating but, hey, whatever works.
Wrap Up
So clearly, I’ve been having fun with FT8 for POTA. I consider it to be another tool in the toolkit. There are times when I will make good use of it but there will also be times to use other modes.
This past year, Joyce/\K0JJW and I did quite a few Summits On The Air (SOTA) and Parks On The Air (POTA) activations, often as part of an RV camping trip. During this time, we made some improvements to our portable gear. For SOTA, we primarily use the VHF/UHF bands but we have been sprinkling in a bit more HF activity. For POTA, we often don’t have a Height Above Average Terrain advantage, so we definitely use the HF bands.
The ICOM IC-705 is a great backpack portable rig for SOTA and POTA.
Our main goal was to have a backpack portable station for SOTA and POTA that can cover HF through 70 cm, on the most popular bands/modes including CW, SSB, FM and FT8.
Using The IC-705
This 4.5 Ah battery from Bioenno is a compact, lightweight battery for portable operating.
The Icom IC-705 is a great transceiver for covering most HF, VHF and UHF bands. With an external battery, the transceiver puts out 10 watts of RF power. (This is a bit less than the 50 watts from our Yaesu FT-90, which is our default choice for 2m and 70 cm SOTA.) We have accumulated a number of Lithium Iron Phosphate batteries from Bioenno. They are all set up with PowerPole connectors and are easily interchanged. See a previous post, My SOTA Battery Journey.
Arguably the biggest weakness of the IC-705 is the lack of an internal antenna tuner for the HF bands. Of course, you can operate without a tuner by making sure your antenna is always 50 ohms. I find that limiting, especially under portable conditions where the antenna configuration might be compromised. Also, some common end-fed antennas that cover multiple bands are not a good match for all bands. There are external automatic antenna tuners available for the IC-705, so initially those looked like a good solution. Then I remembered that I had a small MFJ-902 Travel Tuner that could do the job. The MFJ-902 is a classic T-network with two variable capacitors and one variable inductor. I gave it a try and was impressed with how easy it was to tune using the SWR meter of the IC-705. This thing is simple and it works.
The MFJ-902 Travel Tuner is a simple T-network antenna tuner.
The rear panel of the tuner has two SO-239 connectors, one for the transceiver and one for the antenna. I put a BNC adapter onto the transceiver port and used a short BNC cable to connect to the IC-705.

The Travel Tuner is compact and not very heavy, so it works out well for backpack portable use. It can handle up to 150 watts, which is overkill for the IC-705 but it may come in handy when used with a higher power transceiver. Still, I am on the lookout for an even more compact (probably lower power) manual antenna tuner.
A typical end-fed half-wave wire antenna for 15 meters.
We have collected a variety of HF antennas, focused mostly on 20 meters and higher. These are typically end-fed, including single-band half-wave designs as well as multiband random-length antennas. These are used in the classic SOTA configuration with one end of the wire supported by a lightweight fishing pole and the coax connection on the ground, fed by a 25-foot length of RG-8X coaxial cable.
FT8 Solution
With the popularity of FT8 on the HF bands as well as 6 meters, I figured we should include that mode in our portable kit. My first thought was to use a compact Windows computer running the standard WSJT-X software. Ultimately, I chose the SDR Control app for the Apple iPad (by Marcus/DL8MRE), which supports specific Icom radios. The iPad connects to the IC-705 via its WiFi connection, which simplifies the connection/cabling challenge. The SDR Control app does cost $49.99, so it is not your inexpensive iOS app but I have found it to be worth the price. Because this app is focused only on iOS and certain Icom radios, it is well-tuned to be a no-fuss solution. I am currently using the app only for FT8 but it has other features and modes for me to explore.

The Powerwerx PWRbox is shown in the photo above, which we often use for operating POTA. (This box is a bit heavy for hiking.) The PWRbox holds a 20 Ah battery as described here. Also shown in the photo is a handy little stand for the IC-705, the NEEWER Folding Z Flex Tilt Head. It does a great job of holding and stabilizing the radio at a variety of angles. (Hat tip to Kyle/KD0TRD.) It is also a little heavy for backpack portable, so it usually gets left behind on a hike.
The Maxpedition bottle holder case works well with the IC-705.
For a protective case for the IC-705, we use the Maxpedition 12-Inch X 5-Inch Bottle Holder. I’ve seen other IC-705 users recommend it and OH8STN mentioned it on his blog. At first glance, the case seems a bit large but this provides enough room inside to stow a small Bioenno battery and other accessories. The side pouch is a good place for storing the microphone and power cord.
Wrap Up
This post shares some new equipment configurations we are using for SOTA and POTA, mostly focused on the IC-705. I really like that radio for portable ops as it is the best solution for operating HF through UHF. The SDR Control software on an iPad has also turned out to be a win for us.
What are you using for your portable station?
Do you have any tips or other operating ideas?
Joyce/K0JJW and I enjoy visiting the National Parks in the US, an activity that naturally combines with Summits On The Air (SOTA) and Parks On The Air (POTA). While planning a visit to Isle Royale National Park in upper Michigan, we decided to activate at least one SOTA summit as well as activate the park for POTA. The park is one large island surrounded by many smaller ones, accessible by boat or airplane. The park is actually closer to Canada than the US mainland.
Isle Royale in Lake Superior.
There is quite a bit of information about visiting the park on the Isle Royale National Park website, so I won’t repeat that here. We opted to take the Isle Royale Queen IV ferry from Copper Harbor, MI to and from the island and stay for three nights at Rock Harbor Lodge on the northeast end of the park.
The closest SOTA summit to Rock Harbor is Mount Ojibway (W8M/UP-059), which soon became the objective for our SOTA activation. This summit had been activated only once, by Scott/WA9STI in 2017. I contacted Scott, who was very helpful in sharing his experience on Ojibway. (There are three other SOTA summits in the park, with first activations by Mark/NK8Q.)
We had four friends join us on this trip, including the hike to Mount Ojibway. Two of them were licensed radio amateurs: Paul/KF9EY and Beth/KB9DOU with Paul joining us in doing the SOTA activation.
Trip Planning
We normally do SOTA activations using VHF/UHF, so this raised the issue of whether that was possible given the remote nature of the island. I poked around on the interwebz and reached out to radio clubs on both the US and Canadian sides. Randy/VA3OJ in Thunder Bay and Bill/KD8JAM on the Keweenaw Peninsula were particularly helpful and they both confirmed they can work stations on Isle Royale from their locations using 2m FM. The distance is not that far, especially to the Canadian side, and it is a straight shot over water.
There were two things that I worried about on this activation: bugs and rain, neither of which were under our control. For bugs, we loaded up on a variety of insect repellents and head nets. However, once we arrived at the island, it was pretty clear the bugs were not bad at all, probably because we were late enough in the year (late August). For the rain, we made sure we had rain gear and synthetic clothes, with the attitude of expecting to get soaked and being able to survive it.
There was no internet on the island (the lodge says they have it but it was not working). Occasionally we would get 1 bar of Verizon LTE service at Rock Harbor but is was not reliable. This meant that we were very limited in sending any email updates out to people. I emailed our plans to interested parties and posted an Alert on SOTAwatch before we hopped on the ferry.
We took the water taxi from Rock Harbor to Daisy Farm Campground.
For equipment, we decided to take our Icom IC-705 and an external battery pack for 10 watts of RF on all bands of interest. Our priority was VHF but we also took along antennas for 40m through 10m. In addition, I configured an iPad for FT8 but we did not end up using that capability.
Mount Ojibway is about a 7-mile hike from the Rock Harbor Lodge, so we decided to have the water taxi drop us off at Daisy Farm Campground and hike in from there, which is about 2 miles one way. We also scheduled the water taxi to pick us up for the return trip. So this set us up for a 4-mile round trip hike with modest elevation gain.
Activation Day
On the morning of our activation, a thunderstorm rolled into Rock Harbor delivering a good dose of lightning to the area. I checked on the status of the water taxi and it was uncertain whether it would be running due to the storm. We sat tight and the weather cleared up enough such that we could go. Still, it was cloudy and the forecast included some rain in the afternoon. I told our group, “We are going to get wet today.”
Mount Ojibway at 1150 feet is part of the Greenstone Ridge that runs along the top of the island. It is also the location of an observation tower, now used as a radio site. The SOTA database shows the summit a bit to the northeast of the tower and the ridge is quite flat with a broad activation zone. My GPS app showed our hike as 1.9 miles one-way, with 540 feet vertical. The trail is well-established and in good condition. There were several narrow boardwalks (narrow planks) over marshy areas that were unnerving for some of our group.
The Mount Ojibway Tower, as seen from the trail.
At the summit, we appreciated some blue sky and nice weather that appeared while we set up the IC-705 and 3-element Yagi for 2 meters. We called CQ SOTA on 146.52 MHz and soon worked KD8JAM and VA3OJ. We kept calling and picked up two more 2m FM contacts: W9GY and VA3DVE. About this time, we set up the endfed antenna for the HF bands and (just barely) worked W0BV in Colorado on 20m SSB. (My phone was not able to spot us but I used my Garmin inReach to message W0BV and he came up on frequency.) I also worked W4GO, who had a decent 55 signal at the summit. But 20m was not working very well for us and I started to consider what changes I should make to the station. However, the dark clouds approaching from the northwest made that a moot point as we packed up our gear and headed down the trail. Sorry, we were not able to do more on HF.
Totally Drenched
On the way down the summit, things got a bit more exciting, and not in a good way. The storm clouds moved in and the light rain we experienced off and on during the day turned into a downpour. My warning of “we are going to get wet today” became all too true. This is the kind of rain that turned the nice, well-developed trail into a river of flowing water. With the rain came lightning, not close by but close enough. We were walking through a well-established forest so the lightning exposure was not too bad. The muddy trail definitely slowed us down as we did not want to add injury to our adventure.
We all were thoroughly drenched by the time we arrived at Daisy Farm Campground. At that point, the storm quit and we hung out on the dock waiting for the water taxi to pick us up. The water taxi apparently had its schedule adjusted and arrived over an hour later than expected. I guess we were on island time.
It was a successful but wet activation. Thank you so much to the radio amateurs who worked us, especially KD8JAM and VA3OJ. We couldn’t have done it without you.
Amateur Radio Fun in the Colorado Mountains
August 4 through 7, 2023 www.ham14er.org
Amateur Radio operators from around Colorado will be climbing ColoradoSummits On The Air (SOTA) peaks and communicating with other radio amateurs across the state and around the world. Join in on the fun during the annual event by activating a summit or contacting (chasing) the mountaintop stations.
This event is normally held the first full weekend in August. Again this year, we will add two bonus days to the Colorado 14er Event. The main two days remain Saturday and Sunday (Aug 5 & 6), while the bonus days are Friday Aug 4 and Monday Aug 7th, for those SOTA enthusiasts that need more than two days of SOTA fun! Be aware that many mountaintop activators will hit the trail early with the goal of being off the summits by (1800 UTC) noon due to lightning safety concerns.
The 14er event includes Summits On the Air (SOTA) peaks, which provide over 1700 summits to activate. (See the W0C SOTA web page or browse the SOTA Atlas.) The Colorado 14er Event was started in 1991, about 19 years before the SOTA program was set up in Colorado. As SOTA grew in popularity, this event expanded from just the 14,000-foot mountains (14ers) to include all of the SOTA summits in the state. We still call it the Colorado 14er Event because, well, that’s where it all started and the 14ers are the iconic summits in the state.
Important: The recommended 2m FM frequencies have been changed to 146.58, 146.55, and 146.49 MHz, to align with the use of the North America Adventure Frequency for SOTA (146.58). The National Simplex Calling Frequency (146.52) may be used as appropriate. There will be plenty of action on the other ham bands, for more information see the operating frequencies page.
Recently, I engaged in a discussion about a UHF (Ultra High Frequency) radio. It seems a ham was complaining that someone had advertised an 800 MHz radio, describing it as “UHF”. His issue was that in land mobile radio, UHF is commonly used to refer to radios in the 380 to 500-ish MHz range. I disagreed with him, saying that 800 MHz is in the UHF range. I was using the ITU definition of UHF, which is any frequency between 300 MHz to 3 GHz. The disagreement was not a big deal but it did cause some confusion. (Of course, I was right and he was wrong, most definitely.)
This got me thinking about how we toss around these terms quite loosely, even though they have precise definitions. Let’s start with the basics, the ITU definitions of radio spectrum.
LF
Low Frequency
30 kHz to 300 kHz
MF
Medium Frequency
300 kHz to 3 MHz
HF
High Frequency
3 MHz to 30 MHz
VHF
Very High Frequency
30 MHz to 300 MHz
UHF
Ultra High Frequency
300 MHz to 3 GHz
SHF
Super High Frequency
3 GHz to 30 GHz
You can see that the basic scheme divides up the spectrum into decades (factors of ten), aligned with frequencies that start with 3 (e.g., 3 MHz, 30 MHz, 300 MHz). If we map the amateur bands onto this system, we see that the bands from 80m (3.5 to 4.0 MHz) through 10m (28-29.7 MHz) fall into the HF range, as expected. Note that 10m almost qualifies as a VHF band, coming in just shy of the 30 MHz limit. That band does have some VHF tendencies. The 160m band (1.8 to 2.0 MHz) actually falls into the MF range even though many of us just think of it as HF.
Let’s take a look at how the US amateur bands line up with this scheme.
Amateur bands within HF, VHF, and UHF ranges. (Some omissions for legibility: 60m, 17m, 12m HF bands.) Graphic: HamRadioSchool.com
There are three VHF bands: 6m (50 to 54 MHz), 2m (144 to 148 MHz) and 1.25m (222 to 225 MHz). The UHF range includes the 70 cm (420 to 450 MHz), 33 cm (902 to 928 MHz), 23 cm (1240 to 1300 MHz), and 13 cm (2300 to 2450 MHz) bands.
The two most commonly used bands in the VHF/UHF region are 2m and 70cm. These bands are home for many FM repeaters, FM simplex, SSB simplex, and plenty of other modes. Common dualband transceivers, both mobile and handheld, operate on the 2m and 70cm bands. These radios are so common that we often refer to them as VHF/UHF dualband radios. Accordingly, you will often hear hams refer to the 2m band as simply VHF and the 70cm band as UHF, as if VHF means 2 meters and UHF means 70 cm. I know I’ve been guilty of saying “let’s switch over to VHF” when I really mean “let’s go to the 2m band.” The 2m band is certainly VHF but VHF does not always mean 2 meters. Similarly, we might say “I’ll call you on the UHF repeater” when it would be more precise to say “I’ll call you on 440 MHz.”
Many times being loose with terminology doesn’t matter but there are times when using the right words can make a difference. Think about this the next time you are referring to a particular frequency band.
Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Join in on the fun during the annual event and see how many of the mountaintop stations you can contact. Be aware that many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.
This event is normally held the first full weekend in August. Following up on the success of the 10-day W0C SOTA event in 2021, in 2022 we will add two bonus days to the Colorado 14er Event. The main two days remain Saturday and Sunday (Aug 6 & 7), while the bonus days are Friday Aug 5 and Monday Aug 8th, for those SOTA enthusiasts that need more than two days of SOTA fun!
The 14er event includes Summits On the Air (SOTA) peaks, which includes over 1800 summits! If you aren’t up to climbing a 14er, there are many other summits to choose from (with a wide range of difficulty). See the W0C SOTA web page at w0c-sota.org.
Important: The recommended 2m FM frequencies have been changed to 146.58, 146.55, and 146.49 MHz, to align with the use of the North America Adventure Frequency for SOTA (146.58). The National Simplex Calling Frequency (146.52) may be used as appropriate. See the operating frequencies page.
Radio operators who plan to activate a summit should post their intent on the ham14er group via the ham14er groups.io website. Also, be sure to check out the event information at http://www.ham14er.org
For a complete list of suggested HF, VHF, and UHF frequencies see this web page.
And there is more!
On the same weekend, SOTA enthusiasts in Montana, Idaho, Washington, and Oregon will activate summits for the Pacific Northwest Not-Quite-Fourteener (PNW-NQF) event. Also on the same weekend, the Southern California SOTA group will hold their SOCAL SOTAFEST. So there will be plenty of SOTA stations to work that weekend.
Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.
This post was updated on June 4, 2022, after the summit house construction was completed.
Perhaps this should be called The Slacker’s Guide to Activating Pikes Peak since I am going to describe the easy way to do a Summits On The Air (SOTA) activation on America’s Mountain. If you plan to hike up, you have my complete support but this post is not meant for you.
Pikes Peak (W0C/FR-004) is about 10 miles straight west of downtown Colorado Springs. See the Pikes Peak website for useful tourist information. At an elevation of 14,115 feet, the mountain towers over Colorado Springs and the other front-range cities. (You may see the elevation listed as 14,110 but it was revised upward in 2002 by the USGS.) This means that it has an excellent radio horizon to large populated areas. On VHF, it is possible to work stations in Kansas, Nebraska, Wyoming and New Mexico. See VHF Distance From Pikes Peak and Pikes Peak to Mt Sneffels. On HF, you’ll do even better.
Getting There
Access to the summit has three options: hike up, drive up via the Pikes Peak Highway or ride the Pikes Peak Cog Railway. Most people will probably choose the highway since the cog rail only gives you 30 to 40 minutes on the summit. (Normally, you return on the same train that takes you to the top. You can try to schedule two one-way trips but that is a challenge.)
After a few years of turmoil and construction, the summit of Pikes Peak is now back to operating normally but with some changes. The new summit house/visitors center is open and it is a beautiful new facility. The Cog Railway is also operational with brand new equipment. There is a new boardwalk that allows easy strolling on the summit and improved views near the edge of the summit.
Pikes Peak Highway
The highway is at a well-marked exit off Highway 24, west of Colorado Springs. There is a “toll” to use the highway (~$15 per person, check the Pikes Peak Highway website for the latest information and a $2 discount coupon.) Starting in 2022, you must have a reservation (2-hour window) to drive to the summit (roughly Memorial Day to Labor Day). The specifics are likely to change, so be sure to check the Drive Pikes Peak page for the latest updates.
The road is paved all of the way to the top and is usually in good shape. The only caution on driving up is that some people get freaked out by sections of the road that have steep drop-offs without guard rails. It is very safe, but some folks can’t handle it. The main caution driving down is to use low gear and stay off your brakes. There are plenty of signs reminding you to do this and during the summer there is a brake check station at Glen Cove where the rangers check the temperature of your brakes.
It takes about an hour to drive to the summit, assuming you don’t dawdle. It is best to drive up during the morning and avoid the afternoon thunderstorms.
On The Summit
The W0C Association Reference Manual (the SOTA rules for Colorado) used to suggest a “qualifying hike” of 100 vertical feet but this item has been removed from the manual. If you decide to do such a hike, I suggest you proceed down Barr Trail which is the main hiking trail coming up from the east side of the peak. Do not try to walk along the road, as the rangers will stop you. The trail starts on the east side of the summit house (towards Colorado Springs) and is marked with a sign. You have to cross over the cog rail tracks to get to it. (Please try to avoid getting run over by the train as it scares the tourists and makes a mess.)
The summit of Pikes is broad, flat and rocky, so pick out a spot away from the buildings for your SOTA adventure. There are quite a few radio transmitters on the peak so expect some interference. Since this is way above treeline, your antennas will have to be self-supporting. For VHF, giving a call on 146.52 MHz FM will usually get you a few contacts and sometimes a bit of a pileup. Be aware that on top of Pikes you are hearing everyone but they can’t always hear each other. It can get confusing. Another VHF simplex frequency worth trying is 146.58 MHz (The North America Adventure Frequency). On the HF bands, pray for good ionospheric conditions and do your normal SOTA thing.
Your body and your brain will likely be moving a little slower at 14,000 feet due to the lack of oxygen. Don’t be surprised if you have trouble deciphering and logging callsigns. Take it slow and monitor your physical condition on the peak.
Bring warm, layered clothes, even in the summer, since Pikes Peak can have arctic conditions any time of the year. Keep a close eye on the weather since thunderstorms are quite common during the summer months. Lightning is a very real danger, so abandon the peak before the storms arrive.
In May, we met up with our friends Paul/KF9EY and Beth/KB9DOU for a trip on the Blue Ridge Parkway. Joyce/K0JJW and I had been on the parkway before but had not completed the whole route. We all thought it would be a great trip to do together, in about a week, so we would not be in a rush. Both couples have Class B RVs (camper vans), which are well-suited for such a trip.
The Blue Ridge Parkway is part of the National Park Service, construction started in the 1930s and took decades to complete. The basic concept is a scenic road with a maximum speed limit of 45 MPH connecting Great Smoky Mountain National Park and Shenandoah National Park. We met at the Smoky Mountain end of the parkway and traveled north to Shenandoah.
Of course, we included some Summits On The Air (SOTA) and Parks On The Air (POTA) activations. The Blue Ridge area is target-rich with SOTA and POTA opportunities.
Clingmans Dome
Our first Summits On The Air (SOTA) activation was from Clingmans Dome (W4C/WM-001), the highest spot in the Great Smoky Mountain NP. This is an easy activation with a half-mile hike (one way) to an observation tower. See my previous trip report here.
We opted for a simple VHF SOTA activation, using a Yaesu FT-2DR handheld transceiver and an RH-770 whip antenna. The observation tower was not too crowded and we were able to make a surprising number of 2m FM radio contacts. We just called CQ on 146.52 and raised a number of home stations, mobile stations, and a few campers. Joyce, Paul, and I all completed at least 10 contacts so we decided to submit the activation for both POTA and SOTA.

Blue Ridge Parkway
Then we headed up the parkway, stopping along the way for photo opportunities, a winery visit, lunch stops, and short hikes. We stayed at different campgrounds for three nights along the parkway. To activate the parkway for POTA (K-3378), we stopped at a picnic area for lunch and set up for 20m SSB. We used our typical POTA setup: Yaesu FT-991 driving an end-fed-halfwave antenna supported by a fishing pole.

The station worked well for us but it was a little slow completing contacts on 20m. A 20 AH Bioenno battery supplied the DC power for the FT-991 and we kept the RF output at around 50 watts. I used HAMRS on my Windows PC for logging and it worked well for me. (That logging program keeps getting better with each revision.) Paul and Joyce preferred to log using old-fashioned pen and paper.

Loft Mountain Campground
We camped the last two nights of our trip together at Loft Mountain Campground in Shenandoah NP. This is a rather unique spot in that the campground is located on top of a broad SOTA summit and is inside a national park. The SOTA summit is appropriately named Big Flat Mountain (W4V/BR-009), while Shenandoah NP is park K-0064. This makes for an easy SOTA plus POTA activation.
The summit is located inside the National Radio Quiet Zone, which may require you to coordinate with the NRQZ before operating. However, the W4V Association Reference Manual says that “the typical SOTA activation does not require coordination,” mainly because it is a short-term, temporary radio activity.
Once again, we operated midday on 20m SSB and had reasonably good propagation. Joyce and I made some stateside contacts but when Paul took over, he snagged a couple of European stations. That might be due to his superior operating skill or maybe the band just shifted. Between the three of us, we made 45 QSOs in about an hour or so.
Summary
We had a fun time on this trip, which is another example of blending SOTA and POTA activities with a camping vacation. Our “leisurely pace” strategy worked out well and we were never in a hurry. Of course, there are always more things we could have done. The Blue Ridge Parkway has plenty of interesting tourist, hiking, and SOTA/POTA opportunities. Too many to do in a week.
We have been looking for an opportunity to activate a SOTA summit in our home state of Indiana. Joyce/K0JJW and I were both born there and misspent our youth there. Of course, you might be thinking “there are SOTA summits in Indiana?” Yes, there are three. Two of them are on public land, one is on private land and apparently inaccessible. These three summits are in the southern part of the state, not too far from the hills of Kentucky.
We were headed south towards the Smoky Mountains and passing through southern Indiana and decided to activate Jackson County HP (W9/IN-002). First, we camped at one of Indiana’s best state parks: Brown County State Park, about an hour away from IN-002. The next day we headed to the Jackson-Washington State Forest, where the summit is located. The Indiana Dept of Natural Resources supplies this trail map. As you’ll see, there are a number of trails that can take you to IN-002, but we chose the most direct route, starting at Knob Lake.
There is a State Forest campground around Knob Lake, so that would be another option for camping out.
The red line shows our track up to the summit, starting from Knob Lake.
We headed up a gated road that was labeled “Trails 2 and 3”. This road narrowed into a trail and we took a left turn at the Trail 2 sign. This is slightly tricky because Trail 2 goes off to the left and it continues on straight. The “left” Trail 2 ascends up to IN-002, for a total elevation gain of 465 feet and a distance of 0.7 miles. Go Left.
Once on top, we unpacked our recently purchased Icom IC-705 transceiver. This seemed like a good choice for this activation. While we were sure to try good old 2m FM, there was a good chance that we would get skunked on VHF at this rural and not-too-high summit. Sure enough, 2m FM was silent, even using the mighty 3-element Yagi antenna.
Next, we set up the end-fed halfwave for 20 meters, hoisted by the popular extendable fishing pole. OK, I admit that I had to do some fiddling around with the antenna to get the SWR to behave. Somehow, the test run at the campsite the day before was not sufficient. The SWR was way too high for the “I like 50 ohms” Icom, so some adjustments were required. After an unreasonable amount of fiddling, we put out an SSB signal on 20 meters that seemed good.
The band conditions were not great but they were not terrible. Calling CQ did not seem to work very well, so we tuned around and worked a number of Parks On The Air (POTA) stations to get our 4 QSOs. At that point, we declared victory and headed back down the hill.
This summit was easy to access and an easy hike. If you are in the area and want to knock out a Hoosier SOTA activation, this one is a great choice.
This is a report on my single-operator contest effort during the ARRL November Sweepstakes (Phone) HF Contest. Some other potential titles for this article are:
A Slacker's Guide to Working the Sweepstakes
How To Almost Work 50 States On a Weekend
A Simple Way to Get On the HF Bands
Contests on the HF bands can be a fun way to make a lot of contacts and get some new states or countries. The ARRL Sweepstakes promotes contacts between US and Canadian stations, so it is an opportunity to work those states and provinces.
The Yaesu FT-950 is a capable 100-watt transceiver for HF and 6 meters.
The Club Challenge
I don’t usually work the Sweepstakes contest but Bill/K0UK put out a challenge to the Grand Mesa Contesters club to get on the air and contribute whatever points you can to the aggregate club score. I thought this was a good idea and decided to join in the effort. I already had committed to teaching a General License class on Saturday, so that limited my operating window to mostly Sunday. No problem, I could still make a significant number of contacts on Sunday.
I read the rules for the contest to make sure I knew the operating times, entry categories, what stations I could work for points, and the contest exchange. Sweepstakes has a complicated contest exchange, that includes a serial number (every contact gets a unique sequential number), precedence (operating class), your callsign, the last two digits of the year you were first licensed, and your ARRL section. Wow. For me, the section is just Colorado (abbreviated CO), but some states have multiple sections. It is a great idea to have the list of ARRL and RAC (Radio Amateurs of Canada) sections available. So the information I gave to the other station was something like this: 105 A K0NR 77 CO. In the example, 105 is the serial number that incremented with each radio contact.
Antenna Project
It turned out that my HF antenna at the house fell down some time ago because the rope holding the wire had rotted away. So my first task was to do a quick but effective antenna installation. We have a 30-foot Ponderosa pine in the backyard, which is my preferred antenna support. I have a number of wire antennas stashed away in my basement, including dipoles, end-fed halfwaves, G5RV’s, etc.
An example of a MyAntenna end-fed long wire (EFLW) antenna with 9:1 matching transformer.
For this contest, I decided to use an end-fed antenna from MyAntennas.com, about 44 feet long. This antenna has a 9:1 matching transformer (an “unun”) that matches the high-impedance of the wire to something closer to 50 ohms. An antenna tuner is required to do the final matchup over multiple HF bands. This antenna is long enough to be effective on 40 meters and any higher band, which matches my usual operating habits. I had a Yaesu FT-950 transceiver available which has an internal tuner that was able to match the antenna on 40m, 20m, 15m, and 10m. This is not an end-fed halfwave…it is a “random” length of wire that is not resonant on any ham band but will radiate pretty well using the matching transformer. The advantage of this antenna is its simplicity and ability to handle multiple bands, with the push of the internal antenna tuner.
My main challenge was to get this antenna up into my favorite Ponderosa pine tree. Again, I took a simple approach. I grabbed my spin-cast fishing pole, attached two 5/16-inch hex nuts to the end of the line (to act as a weight), and cast the nuts up over the top of the tree. This may sound difficult, but it only took me three casts to get the fishing line on a limb that I liked. I let the line out and let the weight drop to the ground. Then I attached a 1/8-inch synthetic rope onto the fishing line and pulled it back up over the tree. Soon, I had my antenna support rope passing over the very top of the tree. It was a simple matter to attach and hoist the undriven end of the antenna to the top of the tree. The antenna is longer than the height of the tree, so I sloped the antenna away from the tree.
A length of RG-8 style coax connected the antenna and the transceiver in the ham shack. I did not ground the antenna transformer or add a counterpoise, hoping that the length of coax would be sufficient to act as a counterpoise. This worked out OK and the FT-950 was able to drive the antenna using just the internal antenna tuner on all bands.
Station Setup
You don’t have to have a computer to log your contacts during the contest, but you really should. Even with 50 contacts written on paper, it becomes difficult to remember which stations you’ve already worked. Also, the logging program automatically generates the serial number mentioned above. Very helpful.
The N1MM entry window shows the serial number of the current QSO plus the contest exchange from the other station.
For most contests, I use the N1MM Logger+ software, which is arguably the standard in ham radio contest loggers. It is free to use and is available here. I probably use about 10% of the power of this software but it is relatively easy to use, once you get familiar with it. It has templates for all of the contests, so it keeps track of your score and warns you if you’ve already worked a station. It automatically generates the cabrillo format for submitting your log electronically.
Results
With a 100-watt-and-a-wire station, you have to compete with much more capable stations during a contest. These folks may be running 1kW and gain antennas. I used the “search and pounce” technique, tuning around to find strong stations calling CQ. I typed the callsign into the logging program to make sure we have not already worked and then I called them, just saying my callsign. If they hear me, they will call me back, providing their exchange information. I enter that into N1MM and give them my info. It is as simple as that.
I can usually judge how well my station is doing by how quickly I can contact another station. If they answer me on the first call, that’s great. If it takes a few calls, it usually means that someone else is beating me out in the pileup. I was happy with the performance of the station — I was making contacts at a decent rate.
I made 187 QSOs in about 7 hours of operating, which works out to one contact every 2.5 minutes or so. That rate is not going to win the contest but it was good enough to keep me having fun.
The scoring multiplier for the contest is ARRL and RAC sections, with a maximum number of 84 sections. I worked 66 of them, so not too bad but not a clean sweep. I worked 45 of the 50 US states, missing South Dakota, Oklahoma, New Mexico, Utah, and Alaska. Except for Alaska, the missing states are relatively close to Colorado, so a little more time on 40m (or 80m), for shorter skip distance, would probably have gotten them. The point is that you can achieve Worked All States (WAS) on a single Sweepstakes weekend.
This is a good example of how to get an HF station up and running and make some radio contacts. I often encounter hams that are new to HF and not quite sure how to get on the air. It does not have to be complicated…get a basic transceiver, power supply, coax and a wire antenna and give it a try. Doing this on a contest weekend means that you’ll have plenty of stations to contact.
Ham operators make radio contacts on a routine basis. We call another station or another station responds to our call, we exchange some information, maybe chat for a while and then finish the contact, clearing out with our callsigns. Most of the time we clearly know whether we had a valid radio contact, commonly referred to as a QSO.
Sometimes it is not so clear. I hear a DX station calling CQ…I call him (giving his callsign and my callsign) and I hear him say “your report is 5 and 9” so I say “QSL and 73” and put him in the log. Did I really work him? Maybe not. Did he hear my callsign correctly? Was he even talking to me? Not sure.
The question of what constitutes a valid radio contact has been asked for decades. Edward Tilton W1HDQ in the “The World Above 50 Mc” column, QST Magazine, March 1957 wrote this:
As amateurs we are presumed to be engaged in communication. This implies exchange of information, not just identification of one another. Thus, a reasonable definition of a QSO, for amateur purposes, would seem to be an exchange of useful information. Otherwise, why communicate at all?
Tilton goes on to say:
The minimum exchange for two-way work to be considered a contact has been fairly well standardized on a two-stage procedure: positive identification of calls at both ends, and the complete exchange of signal reports. The latter is about the shortest item of information that can be transmitted between two stations that will have any meaning at all. The form varies with various operating activities, but the basic idea of mutual exchange remains in all.
Actually, the exchange of signal reports may be replaced by some other “exchange of information.” For example, during VHF contests the standard exchange of information is usually the 4-character grid locator. Signal reports are not usually given.
A definition for a valid QSO is: A valid contact is one where both operators during the contact have 1. mutually identified each other 2. received a report, and 3. received a confirmation of the successful identification and the reception of the report. It is emphasized that the responsibility always lies with the operator for the integrity of the contact.
Let’s take a practical look at the IARU definition and what it means:
1. mutually identified each other
You exchange callsigns with the other station (making sure you have them correct). This tends to happen naturally as part of the calling process in amateur radio.
2. received a report
You exchange a signal report or some other information (grid locator, contest exchange, …)
3. received a confirmation of the successful identification and the reception of the report.
You acknowledge that you have the information from 1 and 2, by saying “QSL”, “Thank you” or something similar.
Some Scenarios
The rigor applied to making a contact does vary depending on the specific situation. Here are a few specific examples that will help explain this.
FT8
The WSJT-X software used for making FT8 contacts has IARU Steps 1, 2, and 3 embedded into its communication protocol. FT8 is intended to work well under weak-signal conditions, so the software implements a rigorous use of information exchange. Appropriate use of this software guarantees a valid QSO.
These are the FT8 messages for K0NR working W1AW.
The QSO starts with one station calling another (callsigns are exchanged). The standard FT8 messages (see figure) show that KØNR calls W1AW with grid locator included (TX1). Typically, W1AW would respond by calling KØNR and providing a signal report. (Signal reports are in decibels, just a number.) KØNR responds with TX3, which does two things: sends “R” to indicate that the signal report from W1AW was received AND sends the signal report of -15 dB to W1AW. When W1AW receives that transmission, it knows that callsigns and signal reports have been exchanged and sends RR73 to complete the QSO. KØNR may respond with a 73 message, but that is not required for a valid QSO.
I realize that if you haven’t worked FT8, this may be confusing. If so, just note that the design of the WSJT-X software leads the user through these specific messages to ensure that the three IARU steps happen.
VHF Contest QSO With Weak Signals
Radio contacts during VHF contests can be a bit casual: one operator calls another (callsigns exchanged) and they tell each other their grid locators. IARU Step 3 (the QSL or acknowledgment) may be assumed or perhaps one of the operators just says thanks or 73 to indicate the contact is complete and they are signing clear. But when the signals are weak, VHF operators tend to be more careful about making sure they made the contact.
Here’s a weak-signal CW QSO between KØNR and W9RM:
W9RM responds and sends his grid (DM58) W9RM: KØNR KØNR de W9RM DM58 DM58 DM58 BK
KØNR responds with multiple “R”s to indicate that the grid was received and sends his grid (DM78) KØNR: R R R DM78 DM78 DM78 BK
W9RM responds with multiple “QSL”s to acknowledge that the information is complete
W9RM: QSL QSL QSL de W9RM BK
KØNR would probably reply with “73 73 73” but that is not necessary for a valid QSO
HF Contests
HF contests are fast and furious, with a high value placed on quickly making contacts. Thus, they tend to use the bare minimum to complete a QSO. Let’s take the example of a Big Gun station making multiple contacts in succession, otherwise known as “running.” Here, ZF1A is working the CQ Worldwide DX Contest with a number of stations calling him. He initiates the radio contact with “QRZ?”
ZF1A calls QRZ?
ZF1A: ZF1A QRZ?
KØNR calls ZF1A by just saying his callsign KØNR: Kilo Zero November Romeo
ZF1A calls KØNR and gives the contest exchange: signal report (always 59 in a contest) and CQ Zone (08 in this example) ZF1A: KØNR 59 08
KØNR responds with a “Roger” to indicate the information was received and provides a signal report and CQ Zone 04 KØNR: Roger 59 04
ZF1A acknowledges the information and calls for the next station ZF1A: Thank you, ZF1A QRZ?
This is a fast and tight exchange. Note that to save time, KØNR did not say ZF1A’s callsign during the contact. It does have the potential of a broken QSO if the operators are not paying close attention. KØNR must be sure he is hearing ZF1A’s callsign correctly and that ZF1A sent KØNR’s callsign correctly. Similarly, ZF1A will make sure he has KØNR’s callsign and exchange before moving on. If ZF1A is not sure of KØNR’s callsign and exchange, he will ask for a repeat. Sometimes the running station just calls QRZ? to complete the contact so IARU step 3 is implied. (If ZF1A did not have confidence that the QSO was complete, he would have asked for a repeat.)
Parks On The Air (POTA)
From the POTA rules: “POTA does not require a formal exchange, though many activators will wish to receive real signal reports, names and locations.” My experience is that the park Activator usually sends a (real) signal report and the park number (e.g., K-4404). The Hunter usually sends a real signal report and state. Something like this:
KØNR calls CQ POTA
KØNR: CQ CQ Parks on the air Kilo Zero November Romeo
KØJJW answers him KØJJW: KØNR this is KØJJW Kilo Zero Juliet Juliet Whiskey
KØNR responds with the signal report and park number KØNR: KØJJW you are 57 in park K-4404
KØJJW acknowledges the information and provides a signal report and state. KØJJW: Roger. You are 5 6 into Colorado. Thanks for the activation.
KØNR confirms that the QSO is complete and moves on to the next station KØNR: QSL and thank you, this is Kilo Zero November Romeo, Parks On The Air
When conditions are marginal, a POTA QSO will naturally tend to have signal reports and QSL messages sent multiple times to make sure that the information gets through.
Summits On The Air (SOTA)
The general SOTA rules state “QSOs must comprise an exchange of callsigns and signal reports, it is strongly recommended that the summit identifier be given during each contact.” SOTA contacts are similar to POTA contacts in terms of format, except the summit number (e.g., W0C/FR-004 ) is exchanged instead of the park number.
Time Constraints
Meteor scatter (MS) is an interesting case, mostly because it can take a long time to complete the QSO. The two stations are transmitting to each other on alternating time windows hoping that a meteor will streak by and leave an ionizing trail so that a radio contact can be made. It is common for an MS QSO to take 30 minutes or longer.
The message sequence is similar to the FT8 example, so I won’t repeat it here. Imagine sitting in front of your computer patiently waiting for the right meteor burst to occur so that 1) callsigns are exchanged 2) signal reports are exchanged and 3) a final acknowledgment occurs. This raises the question of how long is too long to count as a valid QSO? I don’t know of a specific standard but most people would agree that if the three steps occur over several days, it is probably not a valid QSO. It seems like most hams working MS complete their contacts within a few hours, typically less.
One more question: what information do you need to record concerning the QSO? This will also vary depending on the circumstances, but most hams log callsign, signal reports, time (UTC), frequency or band, and mode. Note that Logbook of The World does not store signal reports but does require and store the time of the QSO, along with the band and mode. Another example: when submitting a contest log, the context exchange from both stations must be included (and these are checked against other submitted logs). The point is you need to be thinking about how the QSO information is going to be used and recorded. [Thanks, Bob/WØBV]
Summary
The three steps in the IARU definition of a valid QSO can be summarized as: 1) exchange callsigns 2) exchange signal report or other information and 3) confirm that #1 and #2 happened. This still leaves some gray area when it comes to deciding whether a QSO was valid or not. Most of us have had that funny feeling at the end of a marginal contact: should I put this in the log or not? This is where the final IARU advice applies: The responsibility always lies with the operator for the integrity of the contact.
Visiting Yellowstone and Grand Teton National Parks is a favorite trip for us. It is a 9-hour drive to get there from Colorado, so we can make it in a day. In September, we visited these two parks with a blend of activities in mind: RV camping, hiking, viewing wildlife and ham radio. The ham radio part means Summits On The Air (SOTA) and Parks On The Air (POTA).
The Teton mountains tower above the Snake River.
Our trip started from Monument, CO, followed by a stop at our cabin near Trout Creek Pass. Heading north, we spent one night at Steamboat Lake State Park (Colorado), which broke up the road trip into smaller sections.

Grand Teton NP
Grand Teton NP listed 27 activations for POTA (POTA K-0031) which is really not that many activations for such a well-known national park. The park and the surrounding national forests have many SOTA summits available, some quite difficult to climb (such as 13,770 foot Grand Teton). We camped two nights at Colter Bay RV Park, inside the park. This is a decent RV-style campground with full hookups and campsites packed in a bit tight.
Joyce/K0JJW campsite operating POTA from the Grand Teton campsite.
Our usual POTA station is the Yaesu FT-991 driving a single-band end-fed halfwave (usually 40m, 20m or 17m) supported by a fishing pole and powered by a 20 Ah Bioenno battery. Joyce/K0JJW likes to use a paper log but I usually log my contacts with HAMRS, either on my notebook PC or an iPad. HAMRS is a relatively new logging program that runs on most operating systems (Windows, Mac, Linux, iOS, Android, etc.) It is tuned for portable operating, with templates for SOTA and POTA. Check it out, if you haven’t tried it.
One unfortunate surprise while operating from the campsite was a ton of RFI coming from the electronic devices in use by the herd of RVs. The noise floor on 20m was S5— not so good. It seems that today’s RV enthusiast brings along complete wireless network support with internet access points, WiFi routers, and their associated Part 15 emissions. Oh, well.
After setting up on 20m SSB, K0JJW and I both completed 10 QSOs with some difficulty. We were clearly being heard but we had trouble digging signals out of the noise.
Next up was a VHF SOTA activation on Signal Mountain (W7Y/TT-161). This is an easy-to-access drive-up summit with a great view, highly recommended with or without a SOTA activation. We debated on whether to use HF for SOTA on this trip. Normally, we’ve stuck to VHF/UHF on SOTA summits, as part of the Height-Above-Average-Terrain experience. However, knowing that Northwest Wyoming is a bit sparse for VHF activity, we could easily get skunked on a SOTA activation (less than 4 QSOs). Despite that, we opted to stick with VHF for SOTA and focus on a successful activation (1 QSO or more), with or without the SOTA points. On Signal Mountain, we worked two stations on 2m FM, including Steven/KB7ITU in Rexburg, ID, about 60 miles away. (Hey, we worked another state on VHF!)
Speaking of VHF, we used our dualband mobile (IC-2730A) to listen to the national park repeaters while we travelled through the park. Our dual-receive radio always has 146.52 MHz on one side and “something else” on the other side. When inside large national parks, we’ll set the second receiver to a national park frequency. These are generally conventional FM in the 162 to 173 MHz range. I won’t list the Teton and Yellowstone frequencies here but you can find them with a little searching on the interwebz. For example, see wiki.radioreference.com for Yellowstone NP frequencies.
Yellowstone National Park
Yellowstone ( POTA K-0070 ) had only 22 POTA activations, not that many considering it is the nation’s first national park. It also has quite a number of SOTA summits of varying difficulty.
We camped two nights at Grant Village campground, a basic national park campground. The campground had no hookups but the campsites are well spaced with many trees and flush toilets. (The only problem we had was when the park service booked another group of campers onto our campsite one night.)
Joyce and our RV (Rocky Victoria) at the Grant Village campsite.
During a previous visit to Yellowstone, we activated Lake Butte (W7Y/PA-219). On this trip, we had our eye on Mount Washburn (W7Y/PA-163), a well-known 10k summit and popular hike, but the road that provides access to it was closed for the summer due to construction. (OK, maybe next time.)
Bob/K0NR operates 2m FM from the unnamed summit W7Y/TT-139.
Instead, we decided to try an unnamed summit 8770 (W7Y/TT-139) that was relatively easy to access but had not been activated for SOTA. We found some trip reports that said there is a nice trail to the summit and the only complaint was that the summit does not have a view due to the many trees. We parked at the Divide Trailhead, about 12 miles west of Grant Village. The trail is 1.8 miles in length (one way) with 700 feet of elevation gain. So not too difficult but a real hike. The summit is broad and sure enough with lots of trees, so no view. Practice normal bear precautions on this trail.
Practice standard bear precautions in this area.
Again, we opted for VHF SOTA, knowing that we might not get enough radio contacts for points…but we only needed one contact to qualify as the first activation. We worked two mobile stations passing through the park on 146.52 MHz. Yes, it is good to always be monitoring the calling frequency. You never know who is going to show up.
For POTA, we noted that the Continental Divide Trail National Scenic Trail (K-4558) passes through Yellowstone NP, which would allow for a double activation. The CDT has always been special to me as it passes through Colorado and provides some of the most scenic hiking in the state. It only had 15 activations listed at that time, two of those were ours from when we activated it a month earlier, in Colorado. We choose the Old Faithful area as a good place to activate Yellowstone NP ( K-0070) and the CDT. We set up near the edge of the parking lot, away from the crowds. Again it was the FT-991 driving the endfed halfwave on 20m SSB. It was midday, so we expected good 20m propagation (and a nice pileup for Yellowstone) but the band was not cooperating. We both made at least 10 QSOs for a successful activation, so we count that as a win, but the pileup never happened.
Besides the radio operating, we had a good time touring through the park and looking for wildlife. We saw tons of buffalo, not quite so many elk and deer, but no bears or wolves. We have had better wildlife viewing on previous trips but it was still fun.
Heading South
Then it was time to start home, heading south out of Yellowstone back through Grand Teton. Of course, we were monitoring 146.52 MHz, when we heard Lorene/KG6MWQ on unnamed summit 7586 (W7Y/TT-164). She was on the summit with AE6NH, operating both HF and VHF. It was great to catch a VHF activator in Yellowstone. This was the first activation for TT-164, so congratulations to both of them.
Two POTA activators smiling for the camera (Joyce/K0JJW, Bob/K0NR).
We decided to make a stop at the Colter Village area on the way through Grand Teton NP. Our first priority was to use the shower facilities there. Our second priority was doing another POTA activation.
Yaesu FT-991 set up on small camp table, with microphone and two sets of headphones.
This time we set up in a large parking lot, away from anything that might produce RFI. Again, it was 20m SSB using the halfwave antenna supported by a fishing pole. We sat near the RV on our camp chairs and table. Our typical configuration is to have two sets of headphones so both of us can copy well. We just use the standard handheld microphone which is easily passed between us when we change operators.
Typical antenna setup with fishing pole inserted into a plastic pipe attached to the RV ladder. A wire antenna is hung from the end of the pole.
Later in the day, we exited the park and headed south through Jackson, WY. We stayed overnight at a farm near Afton, WY which is surrounded by Bridger-Teton National Forest (K-4535). Of course, we needed to do one more POTA activation. We searched around for a usable spot to park and then fired up on 20m SSB. Propagation was OK but not great but we got it done.
The next day, we were up and going early, driving the rest of the way home to Monument. It was a wonderful road trip that blended sightseeing, hiking, camping, and ham radio. Let’s go do it again!
