We are rapidly approaching the first anniversary of the strange disappearance of the Lost Island DX Society (LIDS) as first reported on this blog. The LIDS were last heard from via the Fi-Ni Report on September 18, 2012, reporting on the Talk Like A Pirate Contest.
Most people have given up the search for the LIDS, given the extended period of time they have been missing. One consistent rumor circulating in the DX community is that the LIDS were trying to join the Amsterdam Island DXpedition (FT5ZM) for a January 2014 activation of that island. Unfortunately, the LIDS did not realize that the island is in the middle of the Indian Ocean and not in Amsterdam. As the story goes, they had already bought nonrefundable airline tickets to Europe before they found this out. It seems that they may try to recover with a Summits On The Air (SOTA) activation, if they can find a hill high enough within walking distance of their Amsterdam hotel.
Fearing that the LIDS are simply lost somewhere in Europe, a group of hams is petitioning the White House to launch a surveillance drone to find them. As one ham said, “They’ve got them dang drones flying around spying on everyone, they might as well do some good.”
I agree completely. If nothing else, Do It For The Children.
Come join us on Saturday, September 14th, 2013 (9:00 AM to 2:00 PM) at the Prairie Winds Elementary School , 790 Kings Deer Point East, Monument, CO for Tech Day 2013. Tech Day is for beginner to intermediate hams who want to learn more and take that ‘next step’ in ham radio.
Everyone is welcome, no registration is required. Just show up with your bright smiley face, ready to learn something and have fun.
I’ve tried out a number of mapping apps on my iPhone but only recently found one that I really like for hiking. Most of these apps access maps on the network when needed so they are not stored on the smart phone. When you fall of the edge of the network in the backcountry they don’t work. This is a non starter for most of my backcountry hikes. Even if I am close to civilization, I’ll typically drop down into a valley at some point on the hike, losing my network connection.
The MotionX GPS app solves this problem by allowing you to download and storing maps on your iPhone. This requires you to do a bit of planning on what maps you need but it seems to work pretty well. The map quality is good and includes topographic information. (Click on the map image above to zoom in.) No, you probably don’t want to download maps to cover the entire US as you’ll consume all available storage!
Besides mapping, MotionX supports a ton of other features such as tracks, waypoints, compass headings, etc. It is quite flexible and I am still learning all of its tools.
Oh, did I mention this app only costs $1.99? Amazing!
At the Dayton Hamvention, I had picked up the Buddistick™ Deluxe Package portable HF antenna. This antenna is very popular with the Summits On The Air crowd and other QRP enthusiasts. Usually when I am doing SOTA activations, its all about VHF. But being a self-proclaimed HF Slacker, I might get on HF sometime from a summit, so having a Buddistick available seems like a good idea.
I decided I better check this thing out to see if I can make it work on our back deck.
The Buddistick Deluxe Package
After actually reading the instructions, I assembled the antenna and used the clamp mount to attach the antenna on our deck railing. I strung the single radial out on the deck to the recommended length and connected up the transceiver using a short length of RG-8X cable.
Then I used the “by ear” tuning technique to set the tap on the antenna coil. You basically just run the tap down the coil to find the spot that produces the highest noise level at the transceiver. I checked the match using the built-in SWR meter in the Yaesu FT-817 and verified that it was good.
The tapped tuning coil
At first, I tried 20 Meters and discovered an S6 noise level. Not good. Retuning the antenna, I moved up to 15 Meters and found the noise level to be much lower. I also heard a few strong stations working the North American QSO Party.
The mighty Yaesu FT-817 transceiver
I tuned around on the SSB portion of the band and found Bob N4BP calling CQ Contest so I gave him a quick call. He came back to me right away and I gave him the contest exchange of name and state. QSL and I was in his log, no problem! I heard N8II calling and repeated the same exchange, no sweat.
Hey, this QRP stuff really works!
So that was a great first experience with the Buddistick. Now I need to try it from a summit.
Lately, I have been focusing on activating the SOTA (Summits On The Air) peaks near our cabin in the mountains. The basic idea is to identify a SOTA summit, hike to the top and make a few contacts on VHF. On Friday, my spousal unit (Joyce, K0JJW) and I decided to head out to an unnamed peak (W0C/SP-099), southeast of Buena Vista, CO. By no coincidence, this summit had not been activated yet, so we’d get the esteemed honor and glory of being the first.
For lesser known summits, a bit of research is required to figure out the route. My first stop is to check the SOTA database for basic information on the summit. I’ll usually have to dig further using ListsOfJohn and SummitPost. ListsOfJohn is an incredible database of topographical information, listing every summit along with information such as elevation, lat/lon, rise, etc. (The Colorado SOTA information was gleaned from ListsOfJohn.) SummitPost will usually have more detailed information on a summit but only for the more popular ones. The SOTA Mapping Project is another excellent resource with very useful interactive topo maps. And, of course, I also dig out the US Forest Service map for the area, which often gives the best view of access roads.
We drove the Jeep to within a mile of the summit and started hiking up. I posted our route information on ListsOfJohn, so take a look there for that information. The summit is unnamed, so it is referred to by its elevation: 10123. I had my Yaesu VX-8GR burping out APRS packets which were plotted on aprs.fi when we reached the summit.
When we reached the summit, I spotted myself on the SOTAWatch web site using the SOTA Goat app on my smartphone. More importantly, the night before the hike, I sent an email to some of the radio amateurs that were likely to be within VHF range. That paid off and I worked Jim KD0MRC, Walt WZ0N and John K3NOQ on 146.52 MHz FM. Jim was hiking to Harvard Lakes above 10,000 feet, so it was special to be able to contact him on the trail. A little later, I caught KV4AL who was mobile near the top of Mount Evans. While only one contact is required to “activate” a summit, four contacts are needed to earn SOTA points, so I was happy to make these four QSOs. My gear was a Yaesu FT-60 driving a 3-element Arrow yagi antenna.
In addition, Joyce and I generally work each other on the SOTA the summit. The SOTA rules say that “QSOs with others within the same Activation Zone do not count towards the QSO total” which means that one of us needs to hike down a bit to get outside of the activation zone (75 feet vertical feet from the summit). We take turns doing this so that each of us activates the summit and makes a contact with the summit.
We took a round about path back to the Jeep and headed for Bald Mountain. At this point, we were both very tired and the thunderstorms were moving in. We decided to at least check out the access to Bald Mountain (WoC/SP-115) even if we didn’t climb it that day. It turns out that there is a 4WD road that goes to the top of the mountain, so we drove to the summit. The road is very rough in a few spots but the Jeep handled it nicely. At the top, we hiked back down a bit to meet the non-motorized ascent requirement for SOTA. We also did our “work each other” technique while on the mountain so that we each had a contact. I was not able to raise anyone on 146.52 MHz but I did catch Carl K5UK on the 146.745 MHz repeater and worked him on simplex. By this time, it was raining with lightning getting closer, so we abandoned the summit and headed back to the cabin.
Thanks to the guys that took the time to contact us on the two summits.
While digging through the archives, I came across some previously unseen video from the 2012 Colorado 14er Event. Joyce KØJJW and I operated from Mount Sneffels (SOTA W0/UR-001) and this video shows a radio contact with Mark KTØAM on Mount Shavano.
The 2013 event will be held August 4th, see www.14er.org.
There is a very jagged peak just east of Buena Vista, CO called Castle Rock (not to be confused with the city by the same name). I knew this was a SOTA summit (W0C/SP-112) and I had my eye on it for a while now. It is extremely rocky and jagged near its summit, so I was not sure if it could be ascended without a technical climb. A little research revealed that it was climbable but quite steep near the top. SummitPost.org has a good description of how to ascend this peak.
June 2018 Update: since this posting, we have discovered a better route from the south. See discussion on the SOTA page: https://www.sota.org.uk/Summit/W0C/SP-112
Castle Rock
My hiking partner and wife, Joyce K0JJW, joined me on the climb. We managed to get off the preferred route and got into some very steep rock scrambling. Good judgment prevailed and we regrouped and found a more reasonable path but probably cost us an extra hour of hiking. As advertised, it did get very steep at the top. (Study the SummitPost information more carefully than I did.)
Assembling the Arrow 2-Meter antenna
Recently, I picked up an Arrow 3-element Yagi antenna for 2 Meters (Model 146-3). This antenna can be dismantled and carried inside a reasonable size daypack (or strapped on externally). The boom has two threaded holes for mounting the antenna on a camera tripod. I used a MountainSmith trekking pole that can double as a camera monopod and mounted the antenna on it.
Operating with the Arrow antenna mounted on the trekking pole
For this SOTA activation, I kept it simple and just used my Yaesu FT-60 to work 2 Meter FM. Accordingly, I configured the Yagi antenna for vertical polarization. (There are two mounting holes on the boom, so you can choose vertical or horizontal orientation.)
The trekking pole is not self-supporting and does not provide much additional antenna height but it makes the antenna a lot easier to point for extended periods of time. I like to use a trekking pole for hiking, so this is a good way to get a little extra utility out of it. I am pleased with how this antenna system performed and will use it again.
The Noise Blankers continue to publish their Ham Hijinks. Remember: Do Not Take These Guys Seriously. Seriously. Do not do this. Seriously.
There’s lots of great ham radio events coming up this summer. This weekend is the CQ Worldwide VHF Contest, the only “true VHF contest” out there since only the 50 MHz and 144 MHz bands are used. Then there’s the Colorado 14er Event, which includes Summits On The Air (SOTA) activations, on August 4th. (Don’t forget to check out the great new Colorado 14er Shirts!) The Colorado QSO Party is another great operating event, on August 31st.
Remember: There is no such thing as ground.
Think about it: an infinitely large electrical node with zero impedance able to sink an infinite current. Not likely.
The NA-SOTA Group on Yahoo is a great place to meet fellow Chasers/Activators, announce activations and share experiences. You have to submit a ‘join’ request before getting access
Guy/N7UN’s helpful 4-page summary of the steps involved from planning, posting an activation Alert, conducting the activation itself and post-activation activities.
Thanks to Steve WG0AT, we now have a new design for the Colorado 14er Event Shirt. Steve gen’d up a new logo that has the Colorado 14er Event blended with Summits On The Air (SOTA), that is available on a variety of t-shirts, a coffee mug and maybe a few other items. The logo, shown to the left, is a fantastic graphic featuring Ham Radio at Altitude.
Go to Cafepress to view and purchase the items that are available.
Just when things were terminally boring on the amateur radio regulatory front, the ARRL reports that “The FCC is inviting public comments on a proposal from a Massachusetts ham to amend the Part 97 Amateur Service rules to permit the encryption of certain amateur communications during emergency operations or related training exercises.” The FCC is seeking comments on the Petition for Rulemaking RM-11699, submitted by Don Rolph (AB1PH). My email and twitter feed started filling up with passionate pleas to either support this petition or to kill it.
This idea has been around for a while but I don’t recall the FCC considering action on it. The issue is that “messages encoded for the purpose of obscuring their meaning” are prohibited by Part 97 rules for the Amateur Radio Service. (Actually, that is not completely true since an exception exists for control of stations in space and radio-controlled models.) This rule has a very important role in enabling the “self policing nature” of the amateur radio service. That is, everyone can listen to the content of all radio communications, allowing improper use of the spectrum to be exposed. (Note to self: file a petition to require encryption when using 14.313 MHz.)
This rule can be a barrier when ham radio Emcomm organizations are providing communications for served agencies (e.g., the Red Cross, fire departments, medical response, law enforcement, etc.) These served agencies do not want sensitive information passed over the radio “in the clear.” Sensitive information includes items such as medical/patient information, location of emergency responders and supplies, damage assessments, door or gate access codes, etc.
A few weeks ago, I volunteered my time to help with communications for the Black Forest wildfire here in Colorado. So count me as someone that sees emergency communications as a key part of amateur radio. (Gosh, I think Part 97 even mentions this. See Part 97.1a) I also see that the prohibition against encryption is a does get in the way during some incidents.
But I am also worried about opening the door to significant use of encryption on the ham bands. The problem with encrypted messages is that…wait for it…you can’t decode the messages. So how do we maintain that self-policing thing? The fear seems to be that if we open the door at all to encryption, it will enable virtually anyone (amateur license or not) to transmit encrypted messages for unknown and inappropriate purposes.
The challenge is to figure out what limits could be put on encrypted operation to retain the self-policing nature of ham radio while enabling more effective emergency communications. Here are some ideas:
Limit the use of encryption to actual emergencies and training exercises. (This is already in RM-11699.)
Require that radio transmissions are properly identified “in the clear”, with no encryption. That way if encryption is used on a regular basis, steps can be taken to investigate further. (This may already be assumed by RM-11699 but I did not see an explicit statement.)
Require additional information to be sent in the clear with the station ID when sending encrypted messages. For example, the name of the served agency, the nature of the emergency or drill, or anything else that would help a random listener to judge whether it is an appropriate use of encryption.
Require archiving of encrypted messages (in unencrypted form) for some period time, available for FCC inspection.
[Added 28 June]: Avoid international regulation issues by limiting encrypted messages to US stations only.
<insert your idea here>
Still pondering this issue…what do you think?

Update 1 July 2013: See the article by Bruce Perens K6BP Update 8 July 2013: See comments by N5FDL
The ARRL says “no”.
Attention all radio amateurs, this weekend is ARRL Field Day! Don’t forget to get on the air.
Field Day is a flexible event, so it can be anything you want it to be: camping weekend, stay at home, participate with your club, go mobile, whatever you desire. Remember to season to taste.
One more thing: Field Day is not a contest. But you can still keep score.
Oh, remember that the national simplex FM calling frequency of 146.52 MHz should not be used for making Field Day contacts. Like all contests…wait Field Day is not a contest. Whatever.
The results are in from the 2013 ARRL January VHF Contest, which includes the new Single Operator 3 Band and Single Operator FM Only entry categories.
There were 77 entries in the SO3B category, with Rich KV2R having the high score: 6368 pts. Breaking his contacts out by band reveals 50MHz:92 QSOs/18 Grids; 144MHz:83 QSOs/12 Grids; 432MHz:12 QSOs/2 Grids. I operated in the same category but with a lower score: 1311, broken out by band this way: 50MHz:27/12; 144MHz:24/8; 432MHz:3/3. As I recall, 50 MHz propagation was not really that great, which is going to be the major swing factor for scores in the SO3B category. Scanning through the top SO3B entries reveals a relatively consistent pattern of 50 MHz having the highest number of QSOs, with 144 MHz in the same ballpark and 432 MHz significantly lower in count.
There were only 23 entries in the SOFM category, which is probably not a big surprise. While there are pockets of FM activity during VHF contests, historically the fun mode has not been used that much for contesting. The whole idea behind SOFM is to open up contesting to the FM operator. It remains to be seen how effective this will be but if it does catch on, it will take some time to build momentum. Ev W2EV had the high score of 1080 in the FM category, broken out by band here: 50MHz:19 QSOs/4 Grids; 144MHz:27 QSOs/4 Grids; 222MHz:5 QSOs/4 Grids; 432MHz:8 QSOs/3 Grids. W2EV’s score shows just a few grids per band, indicating shorter distance contacts overall. With only 4 grids on 50 MHz, he probably did not benefit from sporadic-e propagation on that band. The second place entry was from Erich KC9CUK who only worked the 2 Meter band, producing a score of 441 with 63 QSOs and 7 grids. The remaining entries had less than 30 QSOs. Almost everyone had contacts on 144 MHz but the usage of the other bands varied significantly.
I have always been most interested in operating 50 MHz and 144 MHz, sometimes adding in 222 MHz and 432 MHz, so I find SO3B a nice addition to the contest. In this category, I get to operate my favorite bands but my score does not get compared with the guys that have built stations that do 50 MHz through light. I suspect there are plenty of other VHF contesters in this same boat.
I find the FM category very interesting, as I have always tried to encourage FM operating during the contests.Clearly, FM is less effective than SSB and CW, particularly when the signals are weak. I don’t know whether this category will attract new operators or not to VHF contests. FM operation needs to hit critical mass because activity generates activity. That is, if you are the only FM contester in your area, its going to be frustrating. Of course, it will help if the established SSB stations make it a point to also work FM.
Oh, one more thing… we still need to get rid of the rule that says no contacts on 146.52 MHz. This rule is counterproductive. Every time I talk with an FM op about “getting on during the contest” they say “OK, so I should just call on five two, right?” I have to explain that calling on the calling frequency is not allowed during the contest (uh, that’s only for FM, you see) and their minds start to wander to topics that make more logical sense.
My June VHF Contest operation was at the cabin DM78av, operating in the new 3-band single-op category this year. Usually, I have been a two-band guy just focusing on 2M and 6M. I drug along my 432 MHz antenna and drove it with 50W from my FT-847, picking up a few more QSOs that way.
My score is down from the previous two years, which I think relates to the 50 MHz propagation. I subscribe to the theory that any June contest that has any sporadic-e is a success, so I am not going to complain. However, it did seem like I spend more time digging weak signals out of the noise on 6 Meters this year. It was often just barely open and the QSO rate was slow.
This certificate for the CQ Worldwide VHF Contest arrived in the mail today, 1st Place Single Operator All Band for Colorado. Most of these contest awards take so long to arrive, I have usually forgotten all about the contest by the time they show up in the mail.
Last year, I had a pretty good run at it with an excellent 50 MHz sporadic-e opening on Saturday that ran up the QSO and grid totals. See my previous report on the contest here.
“The Wilderness Protocol” (ref. June 1996 QST, page 85), recommends that stations (fixed, portable or mobile) monitor the primary (and secondary if possible) frequency(s) every three hours starting at 7 AM local time, for five minutes (7:00-7:05 AM, 10:00-10:05 AM, etc.) Additionally, stations that have sufficient power resources should monitor for five minutes starting at the top of every hour, or even continuously.” The primary frequency is the National Simplex Calling Frequency…146.52 MHz. The secondary frequencies are 446.0, 223.5, 52.525 and 1294.5 MHz.
Here in Colorado, the summer months mean that many people head for the mountains. Mobile phone coverage has improved in many parts of the high country but is still not reliable in all areas. Amateur radio VHF/UHF repeater coverage is extensive but also does not cover the entire state.
The Wilderness Protocol is a good idea but is overly complex for practical use. Here’s my proposal to make it much simpler for practical backcountry use:
Principle #1: Don’t ever rely on a radio or mobile phone to get you out of trouble in the backcountry. Your primary strategy must be self-sufficiency. Avoid trouble. Be prepared for the unexpected.
Principle #2: Know what repeaters are available in your area. We have many wide coverage repeaters available but you need to know the frequency, offset and CTCSS tone (if any). The Colorado Connection is a linked repeater system that covers many remote parts of the state.
Principle #3: In remote areas, monitor 146.52 MHz as much as possible. This applies to backcountry travelers, mobile stations and fixed stations.
I’ve been making it a habit to monitor 146.52 MHz in the backcountry. I often come across hikers, campers, fisherman, 4WD enthusiasts, SOTA stations, mobile operators and others monitoring that frequency. It is fun to chat with other radio amateurs having fun in the mountains.
Just my opinion.

I made it to the Dayton Hamvention this year, after a multi-year absence. Due to that four-letter word known as work, I was not able to arrive until really late Friday night. That left all day Saturday and the half day on Sunday to partake of the event.
Bob K0NR discovers the cover photo for the spring CQ VHF
I’ll start with the obligatory dig at Hara Arena, repeating my tweet:
Hara Arena continues to be everything that I wish it wasn’t.
Check out the posts by Jeff KE9V and Steve K9ZW about their impressions of Hamvention.
I spent some time helping out at the HamRadioSchool.com booth in the north hall. Wow, what a positive response we got from that effort. Stu W0STU’s Technician and General Class books have really hit their mark, finding a good balance between covering the material to pass the FCC exams while also helping students to really get it. We heard quite a few instructors stop by and say “This is what I have been looking for!” If you are teaching a ham radio licensing class, you need to check out the HamRadioSchool.com books….and the companion web site and iOS apps.
One of the high points of the weekend was discovering the poster-size front cover of Spring 2013 CQ VHF with my mountaintop photo on it. Joyce K0JJW took a great shot of me operating from Mt Sneffels last August (Colorado 14er Event and SOTA), so it was an excellent complement to my article: “A Little Mountaintop Operation”.
So I leave Dayton, thinking about the highs and lows for the weekend. There was not much new that really caught my attention. (Disclaimer: I am sure I didn’t see everything there.) I am still looking for an FT-950 with 2 Meters, an Android HT and a D-STAR radio from Kenwood, Yaesu or even Alinco. Also, there is a real trend of vaporware instead of products. I’ve gotten really jaded about this. If a company can’t quote price and delivery, then it doesn’t exist in my world.
As K9ZW pointed out, much of the fun of Dayton is being with great people: some old friends (like my bud Denny KB9DPF) and some new ones, too.
When I purchased my 2003 Ford Escape, I decided to install multiple ham radios and a bunch of antennas. Mostly I use a Yaesu FT-8900 FM transceiver for operating on the 2-Meter and 70-cm ham bands. A while back, I started getting reports that I had alternator whine on my transmit audio. I was perplexed because I thought I had done a pretty darn good job of installing the radio, including connecting heavy 12V power cables directly to the battery. (See K0BG’s web page for more information on battery connections.) I really wasn’t sure if this was a day one problem (and no one ever told me about the crummy audio) or something that had just started. My first course of action was to ignore it and see if it goes away. This strategy failed miserably as my FCC-licensed spouse continued to report that I was “whining”. Finally, I decided to put my alleged knowledge of electricity to work. I got out my trusty oscilloscope and took a look at the voltage near the transceiver. There was about 800 mV of ripple on the DC voltage, as shown below.
The frequency of the ripple was in the audio range, consistent with alternator whine. The frequency of the ripple increased when I rev’d the car engine, so it was clearly coming from the alternator. I was surprised to find that the size of the ripple did not depend much on whether I was transmitting or not. The transmit current is much higher than the receive current, so I expected the ripple to be worse on transmit.
Then I decided to measure the ripple voltage right at the battery, which is shown below. The peak-to-peak ripple is smaller (about 400 mV) than at the radio but still present. I expected the the voltage to be mostly clean right at the battery.
I pondered what to do next. One approach would be to install a filter to eliminate the ripple. However, filtering out a few hundred Hz signal while maintaining a low voltage drop on the 12V power feed is not trivial. More importantly, I had the sense that the Escape’s electrical system was just not operating properly. I decided to take it to my local mechanic, who tested the alternator and determined that a diode had failed. He replaced the alternator for me and the whine is now gone.
I did measure the 12 volt supply with the new alternator installed and the radio transmitting. I was surprised to find that there is still some ripple, a bit less than 200 mV (shown below). Apparently, this is not enough to disturb the FT-8900 signal.
So that’s the story about my alternator whine.
My spouse says “I still whine sometimes” but it has nothing to do with my ham transceiver.
HamRadioSchool.com is off to a great start with a learning system that includes a web site, iPhone app and a great Technician License Course book. The Technician book, written by my fellow instructor Stu Turner W0STU, has turned out to be very popular. Stu did a great job of balancing “teaching the right material” with “focusing on the exam questions.” We’ve used the book in our two-day Tech license class with great success.
Many people have been asking Stu when he’s going to write a book for the FCC General Class License. So, by popular demand, here it is: HamRadioSchool.com General License Course. Using the same creative style that worked well with the Technician book, Stu has delivered an easy-t0-grok book for getting your General Class License.
I was happy to provide technical assistance to Stu for this book and earned the esteemed title of Technical Editor. It even says so on the front cover! (It says Technical Editor because I can’t be held responsible for proper grammar or spelling.)
