I have “a friend” that could probably use this.
The Elecraft KX2 made a big splash with QRP enthusiasts at the Dayton Hamvention this year. HamRadio360 had some good coverage of the product introduction. Basically, the KX2 is a shrunken version of the KX3, covering the HF bands 80m through 10m.
There were rumors circulating that Yaesu would introduce a replacement for the FT-817ND, but that turned out to not be true. It is a good rumor because the original FT-817 was introduced way back in 2001 (according to Wikipedia). Also, Chris Wilson NØCSW was actively soliciting inputs for an 817 replacement at the Central States VHF Conference last summer.
A while back, I did a comparison of the FT-817 and the KX3 (big brother to the KX2). I evaluated the two radios from a VHF/UHF point of view. The FT-817 is the only portable single-radio solution for 50 MHz, 144 MHz and 432 MHz. The KX3 includes 50 MHz standard and 144 MHz is an option. The KX2 leaves out the VHF bands completely to achieve a smaller size.
What’s Next for the FT-817?
Its always fun to speculate on what might be coming in new gear. I expect Yaesu will maintain its position as the QRP transceiver that covers HF/VHF/UHF. It has a long history of delivering cost-effective “do everything” radios. We can look to recent product introductions from Yaesu to get a hint of what might be coming.
The FT-2DR, FT-400DR and FT-991 have all adopted larger touch-screen displays so we can probably expect that for the 817 replacement. However, this will challenge the existing form factor…you can’t just drop a larger display into the existing 817 design. The three newer radios include the System Fusion C4FM digital mode…at this point, I don’t think Yaesu would introduce a VHF/UHF radio without it.
Which raises another question: will the new radio also include a GPS receiver? This capability is a good complement to the C4FM mode in a portable radio. The FT-991 requires you to enter your location manually, which the FT-2DR and FT-400DR use a built-in GPS. But it adds circuitry and complexity so I am going to guess they will leave that out.
I am expecting (hoping?) Yaesu will improve the battery life of the transceiver. (Receive standby current is spec’d at 450 mA.) Even if they don’t improve the current drain, newer battery technology could be used to improve operating time. Also, depending on the form factor changes, it may be wise to dedicate more space for a physically larger battery.
Yaesu will probably improve the overall receiver performance, including advanced DSP features. Many 817 users have complained about the lack of coverage of 162 MHz weather radio in the US. On the transmit side, a little more output power would be nice…maybe match the KX3’s 10 watts on HF. Yaesu could really make the VHF crowd happy (in the US) if they included the 222 MHz band.
Take One Tablet
The radio will surely have a computer I/O port with USB being the most flexible choice. There is an opportunity to innovate a bit here by coupling the radio with Android and iOS tablets. I could see a really nice app that handles logging, CW, PSK31, RTTY, bandscope, and other advanced features. This could take the pressure off having a larger display and loading tons of features into the radio. The most convenient I/O would be wireless, most likely Bluetooth or maybe WiFi. Many of the SOTA and QRP operators already take along a smartphone or tablet for logging and other tasks, so it would be a good fit to that market. The key to this idea is careful human factors design and tight integration with the radio. Do I expect this from Yaesu? Not really. So surprise me and knock my socks off.
Those are my thoughts. Your turn.

Twitter is heating up with rumors and reports of new ham gear to be introduced at the Dayton Hamvention. Elecraft is introducing the KX2 QRP HF transceiver. I know this one is real because Steve WGØAT got a chance to try out a unit, shown here in this video. Also, see the short review by Frank KØJQZ.
VA3XPR broke the news about a VHF/UHF radio that does DMR, D-STAR and C4FM digital modes. This was followed by the announcement of another radio, the DV4mobile, that will handle DMR, D-STAR, C4FM, P25 and some other modes. This is exciting stuff but we’ve been here before and nothing materialized. It is definitely achievable…the technology exists. Someone just has to do the work of creating a product. I hope they do it.
The FCC is thinking about making amateur radio licenses last for a lifetime. See the KB6NU blog and comments on the topic.
The ARRL announced that the August UHF Contest is cancelled, thereby ticking off the hams that like to work that contest. It seems they also ticked off the many hams that have been contemplating participating in the contest for the last decade but just haven’t gotten around to it yet.
Not cancelled but expanded is the Colorado 14er Event, which will go the whole weekend (August 6-7). Check out the ham14er web site for the latest info. Its our 25th year and its going to be fun!
The Atlantic published a decent article on ham radio, focusing on the emergency communication aspect of the radio service. Yay!
Don’t forget to participate in the National Pizza Ovens On The Air (NPOOTA) event. Unfortunately, there’s been some partisan bickering about Obama’s recent activation. In related news, here’s a proposal to abolish the use of Q codes. To which I say, QSL!
After one of our Tech Licensees asked “just how many antennas do I need to cover all these bands?”, I wrote this article at HamRadioSchool.com: Antennas… How Many Do I Need?
Another important question is How Many Digits of Pi Do I Need? It turns out that JPL has figured this out using actual math and the answer is 16 digits. You don’t need anymore than that. Ever.
OK, that’s it for now. No, I am not going to be at Dayton. All of the Cool Kids went to Hamcon Colorado instead.

Summits On The Air -Colorado Style
The conference will be excellent. I hope to see you there!
73, Bob KØNR
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 25th annual event and see how many of the mountaintop stations you can contact. This year the event is expanded to include the entire weekend, August 6 & 7. However, many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.
See the very cool 25 Year Anniversary t-shirts available at http://www.cafepress.com/wg0at
The 14er event includes Summits On the Air (SOTA) peaks, which add over 1700 potential 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
Radio operators who plan to activate a summit should post their intent on the ham14er Yahoo Group. To subscribe to the “ham14er” email list, visit the Yahoo groups site at http://groups.yahoo.com/group/ham14er/ . Also, be sure to check out the event information at http://www.ham14er.org It is also a great idea to post an ALERT on the SOTAwatch.org website.
Frequencies used during the event
Activity can occur on any amateur band including HF and VHF. The 2m fm band plan uses a “primary frequency and move up” approach. The 2m fm primary frequency is 147.42 MHz. At the beginning of the event, operators should try calling on 147.42 MHz. As activity increases on that frequency, move on up the band using the 30 kHz steps. Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.45 MHz, followed by 147.48 and 147.51 MHz.
|Frequency (MHz)||Comments||Frequency (MHz)||Comments|
|147.42||Primary 2m FM Frequency, then up in 30 kHz steps||7.032||40m CW Frequency|
|147.45||Alternate 2m FM frequency||7.185||40m SSB Frequency|
|147.48||Alternate 2m FM frequency||10.110||30m CW Frequency|
|147.51||Alternate 2m FM frequency||14.060||20m CW Frequency|
|446.000||Primary 70 cm FM frequency||14.345||20m SSB Frequency|
|446.025||Alternate 70 cm FM frequency||18.092||17m CW Frequency|
|144.200||2m SSB calling frequency||18.158||17m SSB Frequency|
|50.125||6m SSB calling frequency||21.060||15m CW Frequency|
|21.330||15m SSB Frequency|
|Other Bands/Modes||Standard calling frequencies and/or band plans apply.||28.060||10m CW Frequency|
|28.350||10m SSB Frequency|
Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.

Here’s the event flyer in pdf format: Colorado 14er Event Flyer 2016
Economists see scarcity, supply and demand as fundamental forces in a market. Items that are scarce demand a higher price while items that are easy to obtain tend to have a lower price. A diamond is an example of something that is relatively scarce (and in demand) so it commands a high price. In contrast, wood is generally available and is much less expensive than diamonds.
Then there’s the concept of artificial scarcity. If some items can be made scarce (or even just appear scarce), the price will tend to increase. For example, if I own all of the banana trees on an isolated island, I could reduce the available supply of bananas and command a higher price from all of the banana eaters there. Or maybe I start screening bananas for quality and I put a special sticker on them to brand them as special.
We have a case of artificial scarcity in ham radio, called the DXCC list. This list defines what is considered a separate country when chasing DX. (Actually, the correct term is entity, not country.) For example, Hawaii (KH6) and Alaska (KL7) are considered separate entities even though they are part of the United States. (See Is Alaska a Country?) For someone chasing DXCC entities, because Alaska is on The List, a radio contact with Alaska becomes more desirable. It’s kind of like putting a “premium sticker” on a banana to indicate that it is special.
In my imagination, the DXCC list resulted from a bunch of hams sitting around drinking beer and bragging about how many countries they had worked. One guy, Larry says he just worked Hawaii, bringing his total to 125 countries. His buddy Leroy says, “You can’t count Hawaii because it’s part of the US of A.” To which Larry says, “You bet I can count Hawaii…and Texas too. It’s a whole ‘nuther country.” Clearly, we are going to need an official list to keep track of what counts as a country. A more credible version of how the list got established is captured in this article from the October 1935 QST.
Of course, the two main factors that drive scarcity of DXCC entities is the ham radio population and ease of access. Radio contacts are easy to make with entities that have an active ham population. If an entity doesn’t have many active hams but is easy to get to, someone will probably put that location on the air once in a while. On the other hand, some locations are unpopulated and really difficult to get to. These are not only on The List, they are on The Most Wanted List.
Kingman Reef (KH5) was just deleted from The List, instantly changing it from one of the most desired contacts in amateur radio to a big giant Why Bother. You see, there used to be 340 countries on the list but now there’s only 339. Kingman Reef will now be considered part of Palmyra/Jarvis, so it still has value for DXCC, just a lot less.
As I write this article, there is a major DXpedition (VKØEK) operating from Heard Island, an unpopulated island near Antartica. The only reason those guys are there is that Heard Island is on The List. Take a look at their web site and you’ll see how much time and energy has gone into activating this lonely island. Drop it from the list and suddenly a radio contact with this location is a lot less in demand.
So try to keep this all in perspective. There are lots of radio contacts out there to be made, some more interesting and desirable than others. It is appropriate and necessary that we have the DXCC list, to provide consistency in how we count countries, I mean entities. But really, it all traces back to Larry and Leroy arguing about who worked the most countries.
Thanks to the dedicated DXpeditioners that put these rare locations on the air.

A common topic in the QRP community is the Trail Friendly Radio (TFR) concept for backpack-style operating on the high-frequency bands. I’ve adapted the concept for the VHF/UHF bands, calling it the VHF Trail Friendly Radio (VTFR).
Strong candidates for the best VTFR include the Elecraft KX3 (with 2m option) and the Yaesu FT-817. Heck, both of these radios deliver all of the HF bands, 6m and 2m in one portable package. (The FT-817 also has 70cm.) See my blog post that compares the two rigs.
But the other set of strong contenders for the best VTFR is one of the many dualband HTs available on the market. It is hard to beat the compact, portable attributes of these great little radios for casual use on the trail. I’m not going to review them all but instead talk about my current favorite: the Yaesu FT-1DR. (Yaesu has recently replaced the FT-1DR with the newer model FT1XDR, which is the same design but with an improved GPS receiver and larger battery pack.)
My main usage of the radio is when hiking and doing Summits On The Air (SOTA) activations. This radio has a lot to offer in terms of capability and features, but the main things that stand out are 2m/70cm band coverage, two independent receivers and built-in GPS/APRS capability. Most SOTA VHF operating is on 2m fm so that band is critical, but I also make contacts on 70cm. More important is that together 2m and 70cm covers that vast majority of fm repeaters in my state, providing the best backcountry repeater coverage. The built-in APRS features allow the HT to be an effective tracking device as I move down the trail. SOTA chasers can see my position in real-time and anticipate when I’ll be on the summit. The radio has two separate receivers which turns out to be very useful when on the trail. With two receivers, I can monitor 146.52 MHz (2m fm calling frequency, often used for SOTA) while also keeping an ear on a local 2m or 70cm repeater. Another configuration is using one side of the radio to ping my location via APRS while the other side monitors 146.52 MHz.
The extended receive capability of the radio opens up lots of listening options: AM broadcast, FM broadcast, airband, shortwave and NOAA weather radio. I don’t use these very often but there are times that I want to tune to weather or news.
I am not a huge fan of Yaesu’s C4FM digital mode but do use it on occasion. The DN (digital narrow) mode supports voice and position information simultaneously, so Joyce KØJJW and have been using it to keep track of each other on the trail. The radio provides a basic indication of distance and direction to another C4FM radio.
A few other tips: if you buy an FT-1DR, I recommend upgrading the belt clip to the BC-102 clip from Batteries America. It is way better than the standard one from Yaesu. Michael KX6A created a very handy quick reference card for operating the FT-1D, so consider putting one in your pack.

Today, Joyce KØJJW and I activated Kaufman Ridge North (W0C/SP-085) for Summits On The Air (SOTA). We’ve been on the summit before, including the first ever SOTA activation back in September of 2012. This summit is close to our cabin, so it made for a convenient hike. The mountain is not that difficult of a climb but we encountered quite a bit of snow in March, up to three feet in places, which we tromped across with snowshoes.
My blog posting about the next mountain to the south, Kaufman Ridge HP (W0C/SP-081), outlines a good way to access both summits during the summer. However, a seasonal gate closure (December to April) means we needed to find a different route. We approached the mountain from the north, parking our vehicle on Castle Court (a short side road off of Kaufman Road). We quickly crossed what appears to be private property (empty lot, no signs) to get to the US Forest Service boundary. Once we hopped the fence we were on public lands. We intentionally routed to the east to avoid some houses.
I don’t claim that this route is optimal. We had to break a lot of trail, pushing through the snow. We found a section of trail that had recent snowshoe traffic on it but it wasn’t of much use to us heading to the summit. We followed numerous game trails which appeared and disappeared on the side of the mountain. Mostly, we busted through the snow on our own. Surprisingly, the last quarter mile to the summit had little snow, so we removed our snowshoes at that point and just hiked in boots.
My Yaesu FT-1DR has become my favorite rig for SOTA activations. It covers both 2m and 70cm with dual-receiver capability. it has a built-in GPS receiver and APRS capability that facilitates easy APRS tracking. Joyce and I have a pair of these which we’ve been using to track each other’s positions on the few occasions we get separated on the trail.
After we made the summit, I made a few contacts on 146.52 MHz. Thanks to Jim KDØMRC, Dave KØHTX, Carl K5UK and Candy KEØDMT for giving me my four required SOTA contacts.
The weather turned out to be better than predicted…partly cloudy and temps around 50 degrees F. On the way back down, we retraced our ascent path so we had more of a snowshoe trail to follow. I have to admit that this trip was a good lesson in how off-trail snowshoeing can really be a challenge. This was many times more difficult than a summer trail hike of equal length and elevation gain. Trip stats: 2.6 total miles, 1300 vertical feet.
At least, that’s my story and I’m sticking to it.

Recently, I had another opportunity to take ham radio along on vacation to a Caribbean island, this time to Antigua. This was not a super-gonzo turbo-charged DXpedition. I just worked in some radio action in between snorkeling and beach walking. This is referred to as a “holiday style” DXpedition, or maybe it’s just the slacker approach.
The radio gear needed to fit easily into my luggage. After all, we’ve got snorkel gear to take along. I wanted to put out a healthy signal from the island, so I rejected the idea of running QRP, opting instead for a 100W transmitter. Ultimately, I chose to take a Yaesu FT-991 which is full-power and full-featured but still relatively compact. It easily fit into my carry-on bag along with some other items. Having a built-in antenna tuner was a real plus and it was also good to have the 2m and 70 cm bands.
Choosing an antenna was a critical item. My first thought was to take my Buddistick antenna which covers the HF bands I was interested in working: 20m, 17m, 15m and 10m. I used that antenna from the Virgin Islands and it was really handy for taking to the beach. This time I wanted something bigger under the theory that size does matter. On the other hand, I wasn’t going to take full size yagis for each of the bands. I finally settled in on using End-Fed Half Wave (EFHW) antennas for the 4 bands (from LNR Precision). This gave me a simple half-wave antenna on each band with no coils, no traps, nothing funny going on. These antennas radiate well and have decent bandwidth…any SWR degradation can be tweaked up quickly using the FT-991 antenna tuner.
Steve WGØAT suggested I use the SOTABEAMS 30-foot mast to support the EFHW antennas. It is an incredible mast that collapses to 26.5 inches, small enough to fit into my bag. This antenna set up is common with the SOTA activators: EFHW supported by some kind of lightweight pole. I also tossed in a 19-inch magmount antenna for 2m and 70cm. (I did find a good repeater on on 147.0 MHz but did not spend much time on it.)
Rounding out the kit was an Astron switching power supply, a 25-foot length of RG-8X coaxial cable, a Heil Traveler headset and a few patch cords. I found it tempting to keep throwing more stuff in the bag so I adopted the backpacker mentality of taking just what I needed and not much more. For computer logging, I chose N1MM Plus software, with the log type set to “DX”.
I have to confess that I did manage to break the 30-foot mast early in the trip. The house was on a hill and we always had a strong breeze coming through. One day it flexed the mast enough to break it. This was quickly repaired with duct tape. After that, I did not use the 3 top sections of the mast which reduced the amount of sway in the wind (and stress on the mast).
On The Air
My operating time was a bit sporadic and my operating strategy was simple: work the highest band (of 20m, 17m, 15m and 10m) that had some decent propagation to somewhere. Antigua is not extremely rare but it seemed to attract attention. Typically, I called CQ, worked a few stations and then a big pileup would develop. I made lots of QSOs with stations in North America, South America and Europe. I also made a few contacts into Africa but none with Asia. Signal reports were generally good (S9 +), so the antennas were doing the job.
All in all, I was pleased with the contacts I made, given the slacker effort. I especially enjoyed working 17m, a band I have not spent that much time on. The propagation is similar to 20m but noticeably less jammed with signals.

It’s been a while since I’ve done a January VHF contest from a mountaintop so I decided to give it a try from Mount Herman this year. The ARRL recently changed the contest rules to allow the use of the national 2m fm calling frequency for contests. See Coming Soon: 146.52 MHz in ARRL VHF Contests. I wanted to see how this change would play out in practice when doing a combination VHF Contest plus SOTA activation. In previous attempts, I had to vector the SOTA activity to another 2m fm frequency for it to be a legal contact for the contest. The SOTA + Contest operation is attractive because it has all the elements of a fun SOTA hike coupled with the increased activity of a VHF contest. The contest brings out the weak-signal folks with very capable stations, increasing the probability of making some good DX contacts.
Joyce KØJJW and I hit the trail at 10:30 AM local with the goal of being at the summit around noon (1900 UTC) for the start of the ARRL contest. The trail was icy, but manageable with the gripping devices on our boots. The weather was chilly but not bad for January. At the summit, I configured my FT-60 handheld radio for 146.52 MHz using a 2m half-wave vertical. My first call netted a QSO with Tim, KAØMWA in Castle Rock. I worked a few other stations on 2m fm and then set up the 2m ssb station (FT-817 plus Arrow II antenna). On 144.200 MHz SSB, I contacted two Wyoming stations in grid DN71, about 140 miles away. I also gave a call on 446.0 MHz fm and worked W3DHJ and KE0HBW mobile.

The wind was strong at the summit and kept blowing everything around, making it difficult to operate the radio and manage the antennas. After an hour of operating, I decided to QRT and head on down. I know I missed a bunch of potential contacts, especially having not gotten on 70 cm and 6m ssb.
Except for the short operating time, the operation played out as expected. I was able to work the SOTA folks and 2m fm enthusiasts on 146.52 MHz. I made it a point to not hog the calling frequency, as there are quite a few folks that monitor there. Switching over to 2m ssb, I worked the contest crowd, typically with more capable vhf stations. My score is a whopping 114 points, in the single-op portable category.
Thanks to everyone that got on the air to play radio that day!

Summits On The Air (SOTA) operating events are a great way to promote activity and create opportunities for summit-to-summit radio contacts. Here’s the 2016 calendar, an update of the 2015 list suggested by Guy N7UN. Many of these dates are aligned with VHF events but there will be HF activity as well.
- Jan 30-Feb 1: ARRL Jan VHF Contest + NA SOTA Winter Activity Weekend
Apr 16-17Apr 23-24: North America SOTA Spring Activity Weekend
- Jun 11-13: ARRL June VHF Contest + NA SOTA Summer Activity Weekend
- Jul 16-17: CQ WW VHF Contest + optional for SOTA
- Aug 6-7: Colorado 14er Event + NA SOTA Rocky Mtn Rendezvous + W7 SOTA Activity WeekendW7 SOTA Activity Weekend +
ARRL UHF Contest
- Sept 10-11: ARRL Sept VHF Contest + NA SOTA Fall Activity Weekend
Of course, any day is a good day for SOTA activity. The August 6-7 weekend looks to be the alignment of the planets with four events happening around that weekend. Early August usually offers excellent conditions for hiking the highest peaks in Colorado, so come on out and play.
For more info on VHF SOTA, see How To Do a VHF SOTA Activation.
Get off the couch, put on your hiking boots, grab your backpack, grab your radio but most important: get on the air!

I recently had the opportunity to try out a new ISO-TIP 7700 soldering iron. This is a rechargeable soldering iron without a lot of extra features but it is plenty capable for small soldering tasks. Here’s a few specs from the ISO-TIP web site:
– Fully recharges in 3.5 to 4.0 hours
– Partially charged battery to full capacity in one to two hours
– Up to 125 soldering joints per charge during continuous use
– Withstands high-rate charging without damage
Here’s a short video of the circuit blinking away, proving that I can solder together a simple circuit: Video of circuit blinking Yes, the circuit did work the first time.
I’ve often said that Mount Herman (W0C/FR-063) is the most (ham) radio active mountain in Colorado. Many of us have operated from that summit for VHF contests, QRP events and Summits On The Air (SOTA). Of course, I didn’t have any data to back that claim…until now. A review of the cumulative SOTA activations in Colorado through Jan 1, 2016 shows these four summits as the most-activated SOTA peaks.
|Summit||SOTA Designator||Number of Activations|
All of these summits are relatively close to the large population centers in the state. Also, they not that difficult to get to and some of them have roads that go to the top. Pikes and Evans are both 14ers but can be accessed via 2WD vehicles.
But what makes Mount Herman so special? It does not have a road to the summit — you definitely have to hike it, a little bit more than a mile one way with elevation gain of ~1000 feet. What makes the difference for Herman is that it is in the backyard of the well-known radio ham, goat hiker and SOTA enthusiast, Steve WGØAT. Steve has personally activated the summit more than 30 times AND he
drags along mentors encourages other radio hams to join him. Frank KØJQZ did 22 activations, some with Steve and many on his own. (Frank just achieved SOTA Mountain Goat status, activating enough summits to earn 1000 SOTA points.) Fortunately for me, Mt Herman is about 4 miles as the GPS flies from my house, so I have worked that summit 31 times (usually Steve or Frank and always on 2 meters). I’ve also activated Mt Herman for SOTA three times, as described here: A Soggy Mount Herman SOTA Activation, Mt Herman: SOTA plus VHF Contest and Winter Assault on Mt Herman.
Here’s one of Steve’s fun videos that captures the first SOTA activation of Mt Herman, with his goat crew Peanut and Rooster (SK).
Frank and Steve, thanks for all of the Q’s from Mt Herman over the past years! See you on the air and on the trail.

On the last day of the year, it seemed like a good idea to get in one more SOTA activation. It turns out that I had not been up Mt Herman (W0C/FR-063) all year, even though it’s close by. See this page for the trail description. Joyce KØJJW and I decided to hike up in the morning, reaching the summit around 11 AM local time. This was my third SOTA activation of Mt Herman, but I’ve operated from there many more times in various VHF contests (back before SOTA was a thing in Colorado).
The road to the trailhead (Mt Herman Road, FS 320) was in very good condition but snowpacked and icy. This road is not plowed during the winter but it is often passable with a decent 4WD vehicle. Today, you could make it to the trailhead with 2WD and some careful driving. The trail conditions were typical for winter time: almost completely covered in snow with a few bare spots showing here and there. The trail was packed powder and not particularly icy. Still, we appreciated having traction devices on our boots. This trail can be downright treacherous when it ices up, so traction devices (Yaktrax, Microspikes, etc.) are highly recommended. Trekking poles can be helpful, too.
Once at the summit, I used my Yaesu FT-60 handheld radio and a half-wave vertical antenna to work people on 146.52 MHz. Having notified a number of people that I would be on the air, I actually had a bit of a pile up on 2m fm. In short order, I worked KE5QNG, WA6MM, KH7AL, WG0AT, W7AWH, K9MAP, K0JQZ, K9DBX, W0STU, KD0MFO, WB0ROK, KD0VHD and KL7IZW. Best DX was about 50 miles with W7AWH in Pueblo West. Thanks to everyone that got on the air to work me.
The weather was cold, about 15 deg F, so we didn’t stay too long on the summit and headed back down the trail. OK, maybe “winter assault” is a bit of an exaggeration. Let’s call it a fun hike in cold weather.

The most read post on k0nr.com concerns the use of amateur gear outside the ham bands: Can I Use My Ham Radio on Public Safety Frequencies? Actually, I have two blog postings that cover the same topic but one of them is a bit out of date. They both get lots of hits, but I’ve linked to the one that is updated. This is a hot topic as many people still believe strongly that no ham gear is legal on Part 90 frequencies (read through the comments on that post). This is why I took the time to write about it, attempting to explain it and educate the ham community.
The second hottest post was quite controversial: Are Kids the Future of Ham Radio? I got a ton of feedback on this one. People either resonated with its message or just thought it was crazy. I wanted to start a discussion on the topic so I guess it met that objective. Although it is hard to have a discussion when someone says your post is ridiculous. (Disclosure: the original title of the posting was Kids Are Not the Future of Ham Radio, which I later toned down.)
It’s a bit sad that this next post is still so popular: Solving the Baofeng Cable Problem. There is a really frustrating problem with how the Windows driver works with certain USB interface chips. Many folks who went out and bought low cost Baofeng (and other) radios got totally hosed up by this. Hence, the need for and the popularity of this blog posting.
Mobile radio installations are always a bit of an exploration, so I try to share what I learn when doing one. People seem to appreciate this kind of article and often ask followup questions via email. For whatever reason, my 2012 Jeep Wrangler Radio Install post continues to be a popular post on my blog.
One of my classic articles is the FM/VHF Operating Guide, just some basic information to help people get started with FM and repeater operating. I update it from time to time and it gets quite a few hits.
Hey, thanks for stopping by k0nr.com. Best of luck to you in the New Year.

In November 2005, I took a look at some statistics on FCC amateur radio licenses. At that time, I compared the number of ham licenses to such things as the US population, number of cell phones in use and the number of birdwatchers in the US. Interesting stuff.
Ten years later, we can take a look at the how the composition of FCC licenses has changed. The total number of licenses has grown to over 733k, increasing 11% over 10 years. This is a small growth rate, only 1% Compound Annual Growth Rate (CAGR).
No surprise that the number of Advanced and Novice licenses has decreased because the FCC stopped issuing those licenses. Technicians represent about half of the licenses, a proportion that has remained steady over the decade, increasing 1 point. The percent of Generals increased by 3 points, to 23%. Similarly, Extra Class licenses increased by 3 points to 19%.
I reported the ARRL membership as approximately 152k in 2005. The 2014 ARRL Annual Report shows 165,663 members resulting in a growth rate of about 9% over 9 years (not ten). I’ll go ahead and “spot them” another point of growth in the tenth year and call it 10% over ten years. So it seems that ARRL membership is roughly keeping pace with the growth in amateur radio licenses, put probably not gaining on it.
Another question is how are amateur radio licenses keeping pace with US population growth? During the period of 2005 to 2015, the US population grew about 9%, which means that the number of FCC licenses is actually growing slightly faster than the overall population.

At this point, many of us will ask how many of those FCC license holders are actually active in ham radio. Hard to say…perhaps a topic for another post.

This recycled post from 2008 is still accurate, but I do have my HF antenna up and recently used it for the CQ WW SSB Contest.
I was looking out the window the other day and noticed that my wire HF antenna is laying on the ground. Hmmm, probably doesn’t radiate very well that way. But if I put a long, lossy coaxial cable in line, the SWR will still be good at the transmitter. And I can tell my buddies that it works just fine because “I can work everyone that I hear.” (What a dumb thing to say.)
This made me realize that most of my ham radio activity lately has been on 2m FM. Actually it has been on 2m and 70cm FM, as I tend to lump these two activities together. These days, my VHF/UHF FM rigs have at least 146 MHz and 440 MHz in them (FT-7800, FT-8900, etc.). I cruise down the road and flip on the rig, talk to the locals, talk to the XYL, etc. It is just too easy and too convenient. It fits the mobile lifestyle, whether it means operating a mobile rig in the car or grabbing an HT to take along on a business trip. (I used to run HF and SSB VHF mobile but found that the rigs were rarely used, so I removed the gear from my vehicle.)
Of course, I need to apologize to the rest of the ham community for this failure to act according to accepted social norms. You know how it is…Real Hams operate HF, weak-signal VHF, microwaves, etc……almost anything that is not 2m FM. Every so often I hear that comment about “well, those techs just hang out on 2m FM,” implying that those guys are permanently stuck in ham radio middle school, unable to graduate to the next level. Or sometimes the FM operators are referred to as having “shacks on the belt” which are dependent on the “box on the hill.” The main message is that 2m FM is just too easy, too plug-n-play, too much like an appliance….too convenient. We certainly can’t have that!
Don’t get me wrong…I enjoy HF, DXing, contesting, digital modes, almost anything to do with amateur radio. That’s the cool thing about the hobby…so many bands, so many modes. One of my favorite activities is operating the major VHF contests. (I’ve even been known to make a few CW contacts.) But on a day-to-day basis 2m FM just seems to fit in better.
Some people call 2m FM the Utility Mode, because it is the mode that gets the job done. Last week, we had a weather net activated to track thunderstorms and a few tornadoes. Did this happen on 40m? I don’t think so. Two meters carried the load. Where do most of the ARES and RACES nets meet? Two meters. How is most public service communications handled? Two meter FM. Even some hard core HF DX enthusiasts are known to flip over to 2m FM to tell their buddies that the DXpedition to a rare country is on the air. It is the Utility Mode.
Over the weekend, I was driving through the mountains and heard an aeronautical mobile working stations simplex on 146.52 MHz…lots of fun. Another time, I heard a station calling about 80 miles away (I was in a high spot) and I had the pleasure of making that contact….again, on 2m FM. A few weeks ago, I operated in the Colorado 14er Event from the summit of Pikes Peak. Since many of the mountaintop stations had hiked up, the most popular mode of the day was (you guessed it) 2m FM.
So sorry, I have been hanging out on 2m FM. I’ll try to get that HF antenna back in the air one of these days.

On Sunday, I noticed that Brad WA6MM posted that he planned to activate Dakota Hill (W0C/SR-051) for Summits On The Air (SOTA). Dakota is not a good VHF shot from my house but I was planning to be mobile out east towards Black Forest that morning, so it was worth a try. I texted Brad to let him know I’d be looking for him on 2m fm.
Heading south on Highway 83, the road was gaining elevation when Brad let me know he would soon be on the air. Dakota Hill is 10,929 feet and set back into the mountains, so I wasn’t sure if I could make the RF trip over Palmer Divide to work him. I pulled over at the crest of the hill and made a call. Brad had moved off 146.52 MHz due to some intermod interference and was on 146.55 MHz. Brad was using his trusty handheld radio running 5 watts into a half-wave antenna while I had a 50 watt mobile with a 1/4-wave antenna on the roof of the SUV. We made the contact without too much trouble…his signal was half scale on my meter. I listened to Brad work another station as I drove on, losing elevation and losing Brad’s signal on the other side of the hill. That was apparently THE SPOT to make the contact. Height Above Average Terrain (HAAT) is a key factor for VHF SOTA.
I put WA6MM into the log, scoring 6 SOTA chaser points for the 70 mile QSO. No, this wasn’t a rare DX station, no new record set, nothing that exceptional to report, actually. But it was a fun contact, with Brad hiking to a summit in December and me trying to find a location to work him.
This is why I like VHF on SOTA. Just another example of having fun messing around with radios.

Earlier this year, I was talking ham radio stuff with Brian Hutchison, AI6GH. Brian mentioned that his father was a Prisoner of War (POW) in World War II and built a radio while in a Japanese prison camp. I’ve read articles about vintage and spy radios from WWII, but I’ve never been that interested in the topic. When Brian told me about his father, I thought “Holy Grid Current! He built a radio as a POW? Now that’s interesting.” The more I learned about the story, the more I became fascinated by it.
Brian pointed me to some great resources that tell the story. I started with the March 2013 Newsletter of the Palo Alto Amateur Radio Association. Hiro Kato AH6CY has an interesting article describing two different clandestine radios, one of them built by Captain Russell J. Hutchison, Brian’s father. It was a one-tube shortwave receiver intended to keep the prisoners informed about the progress of the war. Mostly, they wanted to know when the invasion of Japan would occur. The radio was built into and disguised as an ordinary water canteen, obtaining its power from an electric light socket.
The book Prisoners of the Japanese: POWs of World War II in the Pacific by Gavan Daws provides some insight into Hutchison’s parts procurement:
At Davao the Japanese camp commandant put out a call for a prisoner who could fix radios. Hutchison got the job, plus a commission from the senior POW officer to build a secret shortwave set. The camp machine shop was a happy hunting ground for him. He fixed the commandant’s personal radio, an American Zenith. The other Japanese brought in their looted sets, Sears, Roebuck and Montgomery Ward brands, also a 35-millimeter Simplex movie projector with a sound amplifier that needed work. Every chance Hutchison got, he liberated parts. From a broken-down car radio he lifted a couple of tube sockets. He scrounged capacitors and condensers and resistors and a voltage meter, a headset that had survived a fire, everything up to four new tubes still in their packages.
My next stop was the website of Tim Sammons N6CC, who built a replica of the shortwave canteen receiver. This single-tube regenerative receiver has a regeneration control, a main tuning capacitor, bandspread tuning capacitor and an antenna tuning capacitor. See N6CC’s webpage for a schematic and other interesting technical details.
This book is available online: The Signal Corps: The Outcome by Thompson and Harris that provided further background (and the figure at the top of this article). Another valuable resource is First Into Nagasaki: The Censored Eyewitness Dispatches on Post-Atomic Japan and Its Prisoners of War.
This is a intrigung story of technological innovation under the most extreme circumstances. Most of us have never experienced such adversity that these POWs endured. Some of them managed to also built clandestine radios. A truly amazing story to consider as we enjoy the Thanksgiving holiday.
