General License Book From HamRadioSchool.com

Posted on by — 1 Comment ↓

HRS General BookHamRadioSchool.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.)

Just like the Tech book, the General book has a companion iPhone app available on iTunes.

The Updated Incomplete List of Ham Radio iPhone Apps

Posted on by — 5 Comments ↓

iphonesIt is about time I updated one of my more popular posts, The Incomplete List of Ham Radio iPhone Apps from 2011. This was a challenging task back then and has gotten more difficult as the number of ham radio apps for the iPhone has greatly expanded. Still, I will give it a shot and appreciate your feedback to make the list better. I am only evaluating iPhone apps, not iPad apps, since I don’t use an iPad.

In general, I will focus on free or low cost (less than $5) apps that I am actively using.

From the Simple Utility Category:

 Maidenhead Converter (Author: Donald Hays, Cost: Free) Handy app that displays your grid locator, uses maps and does lat/lon to grid locator conversions.

Ham Radio Handbook (Author: Antonis Miliarakis Cost: Free) This app provides some basic ham radio info: Q Signals, Country Prefixes, Band Plans and RST signal reporting.

UTC Time (Author: Michael Wells, Cost: Free) A simple app that displays UTC time and local time.

Ham I Am (Author: Storke Brothers, Cost: Free) A handy app that covers some basic amateur radio reference material (Phonetic alphabet, Q Signals, Ham Jargon, Morse Code, RST System, etc.) Although I find the name to be silly, I like the app!

There are quite a few good apps for looking up amateur radio callsigns.

CallBook (Author: Dog Park Software, Cost: $1.99) Simple ham radio callbook lookup with map display.

Call Sign Lookup (Author: Technivations, Cost: $0.99) Another simple ham radio callsign lookup with map display.

CallSigns (Author: David Fleming W4SMT, Cost: $1.99) This is my favorite ham radio callsign lookup. The features are not much different than the others I have listed but the graphics are nicer and the user interface a little cleaner. I am sure this is mostly personal preference.

There are a few repeater directory apps out there:

iHAM Repeater Database (Author: Garry Gerossie, Cost: $4.99) Geolocation repeater directory. This seems to work well.

RepeaterBook (Author: ZBM2 Software, Cost: Free) I’ve only used this one a bit but it seems to work well and its free.

If you are an EchoLink user, then you’ll want this app:

EchoLink (Author: Synergenics, Cost: Free) The EchoLink app for the iPhone.

There are quite a few APRS apps out there. I tend to use these as my needs are pretty simple….just track me, baby!

iBCNU (Author: Luceon, Cost: $1.99) The first APRS app I was able to get running. It just turned on and worked. It integrates the aprs.fi mapping into the app, so it is easy to use. I recommend this one for most casual APRS users.

Ham Tracker (Author: Kram, Cost: $2.99) APRS app, works OK, uses external maps such as Google and aprs.fi. “Share” feature allows you to send an SMS or email with your location information.

Satellite tracking is another useful app for a smartphone:

ISS Lite (Author: Craig Vosburgh, Cost: Free) A free satellite tracking app for just the International Space Station. It has annoying ads but its free.

ProSat Satellite Tracker (Author: Craig Vosburgh, Cost: $9.99) This app is by the same author as ISS Lite, but is the full-featured “pro” version. Although it is a pricey compared to other apps, I recommend it.

For Summits On The Air (SOTA) activity, there are a few apps:

Pocket SOTA (Author: Pignology, Cost: Free) A free app for finding SOTA summits, checking spots and accessing other information.

SOTA Goat (Author: Rockwell Schrock, Cost: $4.99) This is a great app for SOTA activity. It works better when offline than Pocket SOTA (which often happens when you are activating a summit).

For Technician License training, I like the HamRadioSchool.com app. (OK, I am biased here as I contribute to that web site.)

HamRadioSchool (Author: Peak Programming, Cost: $2.99) There are a lot of Technician practice exams out there but this is the best one, especially if you use the HamRadioSchool license book. They also just released the General practice exam, too.

For a mobile logbook:

HamLog (Author: Pignology, Cost: $0.99) I am not too keen on the idea of keeping a log on an iPhone, but it does come in handy once in a while. More importantly, HamLog includes a bunch of handy tools including UTC Clock, Callsign Lookup, Prefix list, Band Plans, Grid Calculator, Solar Data, SOTA Watch, Q Signals and much more.

Well, that’s my list. Any other suggestions?

This list is out of date – see my updated list of iPhone apps here

SOTA Activation: Aspen Ridge (W0C/SP-084)

Posted on by — No Comments ↓

Spring is finally coming to the Colorado high country so it was time for a SOTA (Summits on the Air) activation. I don’t know which idea comes first: let’s go hiking or let’s play SOTA. I suppose it doesn’t really matter.

I’ve had my eyes on activating Aspen Ridge, which is near our family cabin but I wasn’t sure if the road was open. It turned out to be an easy Jeep ride down Forest Service Road 185 to get close to the summit. Then a half mile hike around and over the occasional snow patch got Joyce K0JJW and me to the summit.

K0NR on Aspen Ridge IMG_1553

My portable station was a Yaesu FT-60 handheld and a couple of antennas. Shown above is my dualband Arrow II antenna with only the 2 Meter elements installed, resulting in a 3-element Yagi antenna. My other antenna is an omni-directional MFJ-1714 1/2-wave whip antenna, which is a little easier to handle for general use. Often that is the only antenna I bring along but this time I decided to add a few more dB of signal by using the Yagi. I also take along a Yaesu VX-8GR that pings my location on APRS (www.aprs.fi/k0nr-7).

After a few calls on 146.52 MHz FM, I worked KC8I in Woodland Park. A few minutes later, I caught Steve WG0AT operating from another SOTA peak (Mt Herman, W0C/FR-063) for the QRP To The Field contest. A little later, I worked Ted N0ZPX who was fishing at Antero Reservoir, then N0VXE mobile near Salida and Ron N0MQJ in Ranch of the Rockies.

This photo shows the beautiful Collegiate Peaks in the background, with plenty of snow still showing. Needless to say, it is a gorgeous view from Aspen Ridge!

Checking Out A Baofeng UV-5RA

Posted on by — No Comments ↓

baofeng uv-5raIn the Winter 2013 issue of CQ VHF magazine, I wrote about some of the VHF/UHF handheld radios available from China. In that article, I reported on the measured performance of a few of the Wouxun and Baofeng transceivers. One of the Baofeng UV-5R radios that I tested showed harmonic distortion that was a bit high on the 2 Meter band, around -40 dBc.

I recently got my hands on a Baofeng UV-5RA, which is a newer version of the same radio (firmware BFB297), so I wanted to check its performance. Like the two UV-5R models I checked, the power output, transmit frequency and receiver sensitivity were all quite solid on both bands. I was more interested in the harmonic distortion present in the transmit signal.

AutoSave1

On the 2 Meter band, the 2nd harmonic measured -48.4 dB relative to the fundamental which is pretty good. Similar to the other radios I measured, the performance in the 70 cm band is a lot better (-56.1 dB).

AutoSave4

This radio has significantly better harmonic distortion than the older UV-5R radio. Of course, this is just a single sample, so performance of other radios may be different.

HF Slacker Works the CQ WPX Contest

Posted on by — No Comments ↓

cq_logoThis past weekend, I had a great time working the CQ WPX (SSB) Contest. I am pretty much an HF Slacker but I do like getting on the air once in a while for these contests. The attraction seems to be the opportunity to make lots of contacts in a short time and picking up a few new countries. The format for this contest is really fun…multipliers are based on the callsign prefix, so “everyone is DX”…sort of. CQ has an awards program (CQ WPX Award) that is also based on prefixes worked, so the contest is a good way to pursue that award. The ARRL recently added CQ WPX Award support to Logbook of the World, which will help with confirming contacts. Us HF Slackers don’t like messing around with actually sending QSL cards when transferring a few bytes electronically is sufficient.

I operated from our mountain cabin, with just 100W to a trap dipole up in the trees. Not a Big Gun station, especially not in this contest. There were quite a few stations on the Caribbean, many of them contest DXpeditions. Conditions were pretty good on 20M and 15M, with 10M also quite usable during portions of the day.

        Band    QSOs     Pts  WPX
           7      39      69   30 
          14      71     142   59
          21      81     163   54
          28       9      24    6
       Total     200     398  149
       Score : 59,302

The last time I submitted a log for CQ WPX was in 2011 with roughly the same station. That year, I made 98 QSOs for a score of 18,920. So this year’s score is an improvement over that effort.

But the most important thing is to have fun messing around with radios.

FCC Grants Waiver on TDMA

Posted on by — 1 Comment ↓

fcc-1From the That Took A Long Time department, the FCC granted a waiver requested by the ARRL that clarifies the rules concerning the use of TDMA (i.e., MOTOTRBO or DMR) on the ham bands. I posted on this topic way back in March 2011, so refer to that article for the background. Update: ARRL article posted here.

I was surprised to find that the FCC quoted my comments that I filed on this proceeding:

Some commenters state the proposed rule change “removes an ambiguity in Part 97 concerning the use of single slot TDMA technology” and it “enable[s] and encourage[s] the adoption of spectrally efficient narrowband technology.”  Comments of Robert Witte at 1.

OK, fine, it was buried in the footnotes but I appreciate the mention. I can now die in peace knowing that my name is in the FCC record and not associated with a rules violation 🙂

Thanks to Jeff K0RM, for pointing this out.

This Spewed Out of the Internet #24

Posted on by — 1 Comment ↓

0511-0701-3118-0930Here’s another update of interesting important stuff spewing forth from the internet.

The Noise Blankers continue to run amuck on these interwebz, with cutting edge reporting like this: Amateur Radio Club Indicted on Ferritte Trafficking Charges, Special Event Station to Mark Departure of Mother-In-Law, and Man Claims CQ Contest Victory Despite No Contacts. In a related matter, still no word on the status of the Lost Island DX Society (LIDS).

The FISTS CW Club has a web page that measures your callsign weight. The basic idea is that shorter is better, so plug your callsign in and the ham with the lowest score wins! Mine weighs 52, what’s yours?

The ARRL Field Day information is available for download. The logo looks pretty good this year! field day 2013

Plain Old Telephone Service (POTS) is on the way out.

Lots of new content on HamRadioSchool.com.  Stu W0STU has been discussing the Technician License Question of the Week and I contributed some Shack Talk articles.

And remember, everything on the internet is true because the government is watching it.

How to Get a $10,000 FCC Fine

Posted on by — No Comments ↓

fcc-1The ARRL web site reported on this Notice of Apparent Liability for Forfeiture from the FCC. That’s government talk for “we are fining you.”

In case you are wondering how you can get fined by the FCC, here’s the sequence of events that resulted in a $10,000 fine for this person:

  • Get a Technician License and then let it expire.
  • Repeatedly transmit on 14.312 MHz, interfering with licensed radio amateurs.
  • Have FCC agents track the signal to your house
  • When the FCC agents enter your house to inspect your radio station, leave the transmitter sitting on 14.311 MHz.
  • Tell the FCC agents that you will remove the microphone from the transmitter and only use it as a receiver.

Hmmm, why does 14.312 MHz sound like a familiar frequency? 🙂

This Interference Seems to Follow Me Everywhere

Posted on by — No Comments ↓

USB chargerA few weeks ago, I was at my day job working diligently on something. I popped up the SotaWatch web site to see of anyone was out activating SOTA summits. Sure enough, Steve (AKA Goathiker, AKA WG0AT) was headed up Mt Herman for the day. (I have recently declared Mt Herman to be the Most Radioactive Summit in Colorado…at least for amateur radio.)

When I had a few minutes break, I went out to my amateur-radio equipped SUV in the parking lot to call Steve on 146.52 MHz. Steve came back to my call and we made a quick contact and he was in the log. Even though he was an easy line-of-sight path away, I had trouble copying him. Opening the squelch revealed that I had a large noisy signal sitting on 146.52 MHz. I didn’t think too much of it and assumed it was coming from the vast array of electronic equipment inside the building.

As I left work that day, I tuned to 146.52 MHz to see how quickly the interference disappeared as I drove away. I was surprised to find that the interference did not go away, it was covering a wide area. On my commute home, the noise was remarkably constant. This interference seems to follow me everywhere! Eventually, it sunk in that the interference was coming from my own vehicle. Huh, I didn’t have that problem before.

When I arrived home, I turned off the ignition and the noise was still there. I started disconnecting everything in sight, trying to make the noise disappear. Finally, I unplugged the cute little USB charger/adapter that was inserted into the cigarette lighter socket. Bingo, the interference disappeared. It seems that this little adapter has a switching circuit in it that is generating a large amount of hash. I have not investigated it fully, but it trashes out a substantial portion of the 2 Meter ham band.

It used to be my favorite adapter. Buyer beware.

The Noise Blankers: Running Loose on the Interwebz

Posted on by — No Comments ↓

noiseblankersI am always on the lookout for great ham radio information on the internet. I haven’t found any lately but I did come across The Noise Blankers radio group web site. It was difficult to tell if these guys are really serious or not but they do have an Official FCC Club Callsign (KF5TQF) so they must be legit. Who I am to disagree with this endorsement from the Federal Government?

The mission statement of the club is:

  1. Do radio stuff.
  2. Have fun doing it.
  3. Show people just how fun it is.

This mission statement is very much in harmony with The Universal Purpose of Amateur Radio, so that is a good sign!

I see that the club has posted cutting-edge reports about a West Virginia ham who bought his wife an Alpha amp for Valentines Day,  a Michigan man that declared himself to be a new DXCC entity and the problem causing the Logbook of The World backup. Check their website frequently for more exciting ham radio news.

I have been unable to confirm the rumor that this group is a renegade element of the Lost Island DX Society (LIDS), still presumed to be missing somewhere in the Chihuahuan Desert.

Bdale KB0G Makes Stuff!

Posted on by

Last week, I had lunch with an old friend, Bdale Garbee (KB0G). Bdale and I had both worked at HP for a number of years and we have been involved in some common ham radio clubs and activities. I followed the test and measurement path with Agilent Technologies when that company was formed, while Bdale stayed with the HP computer business. He is a recognized industry expert in Unix, Linux and all things open source. It is always cool to catch up with him and find out what he has been doing. He recently took early retirement from HP…I am not sure what “retirement” means for Bdale but its not playing shuffleboard at the retirement home!

Coincidentally, a few days later, I came across this video from HamRadioNow of Bdale talking at the ARRL/TAPR Digital Communications Conference. In this talk, Bdale discusses the general theme of making stuff and the satisfaction that is derived from that activity. It is about an hour long so grab a cup of your favorite beverage and take a seat.

 

By the way, check out the other HamRadioNow videos, especially the videos of the DCC technical talks. Good stuff!

What’s All This SOTA Stuff?

Posted on by

w0sotaThe Summits On The Air (SOTA) program is seeing increased activity in the US. SOTA represents another one of those crossover activities that combines amateur radio with another activity, in this case hiking. The whole idea is to operate ham radio from a designated list of summits or to work those radio operators on the summits.

I’ve always had this fascination with Height Above Average Terrain (HAAT) and how that can really make a difference for radio operating, especially on VHF and higher. This means that on most hikes of any altitude, I’ve got some kind of radio gear with me.

To get an idea of how the SOTA program operates, check out these web sites:

The SOTA program provides some structure for this activity and a method to keep score. I’ve noticed throughout my ham radio experience, having a specific goal (usually in the form of an award such as WAS, WAC, DXCC, etc.) has been a good motivator for me. In some ways, I don’t like the notion of “keeping score” entering into a fun hobby, but I have to admit that sometimes it helps. The SOTA database is a robust system that keeps track of summit activations and contacts made. I don’t have a specific goal yet, other than to activate summits when I have the opportunity and to work as many of summits on VHF. (Yes, my VHF/UHF bias comes through again.)

To get a feel for the action, take a look at the Activator Scores, click the Filter selection to W0-USA (or other call area of interest), click on Show!. You’ll see the list of hams that have been activating summits, such as K0MOS, WG0AT, N6UHB and KD0PNK. You will find my callsign a ways down the list. Similarly, you can look at the Chaser Scores,  also selecting the call area of interest and clicking on Show!

But wait, there’s more! The SOTAwatch web site provides a way to spot active summits and to alert people of future activations. Clicking on Summits, leads you to a useful set of data about each summit. For example, Devils Head (designated as W0c/FR-051) is a summit that I activated on 15 Jul 2012, with SOTA info available here.

So check out SOTA…you might find it fun to activate summits or you may just decide to be a chaser. Or maybe both. Anyway it works out, it will be fun!

What Frequency Do I Use on 2 Meters?

Posted on by

HRS LogoOne of the more popular articles on my web site is Choose Your 2M Frequency Wisely, which explains the 2 Meter (144 MHz) band plan. VHF and UHF band plans are mostly local in nature and there is no one band plan that works across the US or North America. So that article is written specifically for the band plan in my own state of Colorado.

I recently wrote a new Shack Talk article for HamRadioSchool.com that covers the same topic in a more general way for North America. I called this article What Frequency Do I Use on 2 Meters? Please check it out!

Need A Logging Program for VHF Contests?

Posted on by

 

vhf logAs I prepare for the ARRL January VHF Contest, I loaded the latest version of VHF LOG, a software program by Dave W3KM. I have used this free program for many years and it just rolled over to version 4.0 to support Windows 8.

VHF LOG is easy to use while covering the basic contest logging requirements for the usual VHF contests (ARRL January/June/September, CQ Worldwide VHF, etc.). It includes a “Post Contest” mode, which is handy for entering a paper log into your computer for electronic submission.

VHF LOG runs on Windows operating systems, 98SE thru Win8. Check it out.

Lost Island DX Society Assumed to Be Lost

Posted on by

LIDSThe rumors have been circulating for some time now, that something terrible has happened to the Lost Island DX Society (LIDS). The Fi-Ni report was last heard from on Sept 18th of last year, reporting on the 3rd Annual Talk Like a Pirate Contest. Previous to that, their comprehensive Field Day report was a bit confused, openly questioning whether Field Day is actually a contest. This has fueled speculation that the LIDS are suffering from some type of psychological breakdown. Others have suggested that this group is perpetually confused and no inference can be drawn from strange behavior.

A reliable source has reported that the LIDS team was actively working on a DXpedition to New Mexico. These plans were alledgedly scrapped after a well-known Big Gun DXer told them that New Mexico is actually part of the United States and is not a separate DXCC entity. This same source has suggested that the LIDS have gone into hiding and plan to resurface just in time for a surprise multi-multi-multi-25-radio entry in the 2013 Poisson d’Avril Contest. However, most radio hams close to the LIDS believe that the team got lost on the way to New Mexico and died of heat exhaustion in the Chihuahuan Desert.

Anyone that has any information on the status of LIDS or that might have heard them on the ham bands, is encouraged to contact this blog as soon as possible. We all hope and pray for their quick, safe return.

50 MHz VUCC Via Logbook of the World

Posted on by

VUCCSome time ago, I qualified for 50 MHz VUCC from another location (rare grid DM67, operating portable). Lately, I have been racking up grids on 6 Meters from my cabin in DM78. Since a VUCC award is good for a set of locations that are within 200 km of each other, these new contacts count as a separate VUCC award entry.

After the ARRL Logbook of the World (LoTW) added VUCC to the list of supported awards, I started watching my grid count climb. When the grid count hit 200, I decided it was time to apply for VUCC from the new location.

There are a lot of things about LoTW that are a pain but getting this award was easy. A few clicks on the LoTW web page and I submitted an application for 50 MHz VUCC using 203 grids. The fees were significant: $46.45. This breaks out as $12 for the award fee, $1 for endorsement sticker (indicates 200 contacts), $3 for an LoTW application fee and $30.45 for confirming the 203 grids (15 cents per grid). This might seem steep until you compare it to the mailing and other costs of getting 200 confirmed QSL cards. Assuming a 100% response rate and an SASE for each confirmation, it costs more than $1 per confirmed grid or >$200. With a lower response rate, the costs are even higher. And this ignores the time it takes to organize and send out the cards.

I happily paid the fee using my VISA Credit Card and the VUCC certificate arrived in my mailbox a week or so later. This is awesome!

Yet Another HT From China (Baofeng UV-B5)

Posted on by

I happened upon this posting from Hans PD0AC about the Baofeng UV-B5 handheld transceiver. Hans has written a number of useful reviews on the El Cheapo Radios from China, so when he wrote “The Baofeng UV-B5 is close to perfect”, it caught my attention. I have a couple of the other radios from China that I blogged about here and here.

I ordered one of the radios from 409shop for $53 including shipping from Hong Kong, and it arrived a few days ago. After playing with it a bit, I downloaded the free programming software and loaded up a few frequencies. The software was a huge improvement over the crapware that came with the UV-5R…it installed easily and seems to work just fine.

I did an initial performance check with my HP 8920A RF Test Set and found the performance to be quite good:

 VHF - transmit frequency error ~50 Hz
       transmit power 4.4W
       fm deviation ~4.5 to 5 kHz
       receive sensitivity ~0.2 uV

  UHF - transmit frequency error ~170 Hz
        transmit power 4.4 W
        fm deviation ~4.5 to 5 kHz
        receive sensitivity ~0.2 uV

I’ve noticed poor harmonic distortion on a few Baofeng radios, so I checked that out. On VHF, the harmonics are about -55 dBc, which is good. I did not check UHF but typically these radios have had better harmonic performance on the UHF band. Hans PD0AC reported similar measured results.

On the air testing resulted in excellent signal reports in terms of audio quality. The received audio is also loud and clear. The user manual is acceptable….mostly clear English but it does have some difficult-to-understand sentences here and there. Like the other radios from China, you’re really going to want to use the programming software to set things up. After that, the controls are quite usable.

Note that, unlike some of the other radios from China, the UV-B5 is not certified for Part 90 use. At least not yet.

A Yahoo group has sprung up to discuss this radio and share information, so check that out.

My overall assessment is that Baofeng has cleaned up the issues with the UV-5R (and don’t forget, I really like that radio!). The UV-B5 is a sweet little radio that will make a splash when it hits the US market.

Proper Kerchunking

Posted on by

Recently, on one of the email reflectors associated with repeater owners, someone asked how to deal with kerchunkers on the repeater. The term kerchunk means to key up the repeater to see if it is there. It just takes a quick push of the Push-to-Talk (PTT) button on the transceiver to bring up most repeaters, resulting in a kerchunk sound.

It seems that this repeater owner had someone that was kerchunking his repeater on a regular basis and it was making him looney. This led to the usual discussion of whether kerchunking is acceptable, legal or  moral and whether it should or should not be considered a capital offense.

Clearly, some radio amateurs have not been schooled in the proper way to kerchunk a repeater. The proper method for kerchunking is to key the transmitter and say your callsign, followed by the word “kerchunking”. This simultaneously identifies your station and indicates the purpose of your transmission.

To make the practice of repeater kerchunking even more efficient, I am proposing the adoption of these new Q signals:

QKC: I am kerchunking the repeater

QKC?: Are you kerchunking the repeater?

Thank you for your attention to this important topic concerning good amateur practice.
