I put my two presentations from HamCon Colorado out on the web: Practical Amateur Radio Measurements and Mountaintop VHF in the Colorado High Country . Also, check out Kelly N0VD’s blog posting on the event.
KB5WIA provides some good tips on EME operating.
Hans PD0AC addresses the question: What’s the Best Chinese Dual-band HT? For best price/performance, he selected Baofeng UV-B5/UV-B6 (and I agree).
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.

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 18 Sept 2013: The FCC dismisses the petition.
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.
Best DX was XE2WK in EL03 on 50 MHz.

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.

Note: This is a repost of an older article with minor edits.
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.
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.
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.
How was your Hamvention?

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

It 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?
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.
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, W0/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!

In 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.
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).
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.

This past weekend, I had to 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.

From 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.

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!
Plain Old Telephone Service (POTS) is on the way out.
And remember, everything on the internet is true because the government is watching it.

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?
