Chinese Kit Invasion
March 9th, 2016 | 
Author: I suppose that I might be a little late to the game, so to speak, but I was browsing through the variety of QRP kits on Ebay the other day and was shocked at what I saw. Many may already be familiar with this phenomena in the QRP kit world, however it was news to me. A new Pixie 2 kit for $3.54 plus a whopping $1.80 for shipping. Now that's a QRP price. The kits were from China. As I considered this, I rationalized that at that price, something was askew, surely the quality was suspect, the parts incomplete and the instructions resembled some graffiti on an inner city wall. I passed it off as maybe a joke and went about my EBay browsing.
A few days later I stumbled upon an entry on the SOTA reflector entitled "QRPp Activation with a $3.56 Chinese Pixie..." by Manuel HB9DQM. Manuel had seen the radio on EBAy and couldn't pass up the opportunity to give it a shot. He not only built the radio, which takes the better part of an hour, but he decided to put it to the test in the field.
Using the configuration above, running 300 milliwatts, he made 16 QSO's from a summit top bench. Pretty cool. 300 mw, wire antenna, battery power and a straight key, ah the magic of Ham Radio.
Of course the radio has limitations, it's crystal controlled, the radio comes with a 7.023 crystal (HB9DQM used a 7.030 crystal) and the bandwidth on receive is very wide, but as Manuel demonstrated, you can have some good, cheap fun with this little radio. He said he was listening to the world news, in English (courtesy of a BC station), while he worked the callers. An interesting diversion.
I did some further research on YouTube and found many happy campers who had purchased and assembled the kit. So I took the big plunge. I even went overboard and bought a couple of extra's as projects for my teenage grandsons who are hams.
There is one thing a little troublesome about this kit invasion however, at these prices, the other QRP kit providers can't compete. What will happen to them? Such is the world these days.
The inexpensive kits aren't limited to Pixie's, there are also '49ers, RockMites, etc.. Some even come assembled. I saw and assembled Rockmite, with a case for $35.00.

Mountain Goat Summit Revisited
A little less than a year ago I summited a mountain, known in SOTA terms as 9431 (it's elevation ASL) with a designator of W5N/PW-019, which put me over 1,000 Activator points and thus qualified me for the Mountain Goat award. This award is one of the most satisfying awards I've achieved in ham radio, including #1 Honor Roll. I did the summit that day with a couple of friends of mine, Fred KT5X (aka WS0TA) and John, K1JD. Both are also mentors to me as I learned the SOTA trade so to speak.
So, nearly a year later, the three of us returned to the same summit. Like the previous ascent we would need snowshoes to get to the top. The hike is a little more than 3 miles round trip and climbs 1,100 vertical feet. The hike starts in Black Canyon with a steady ascent to the shoulder, and then two different steep pitches to the top. The drifts on the summit were significant with our snowshoes sinking 1-2 feet into the snow. There were patches facing the south were the snow had completely melted, however most of the final ascent is on the north side of the mountain.
Below is a brief video of my set-up on the summit. I have configured my 3 band MTR (17m, 20m and 30m) so that I can hold it in my hand. As you will see in the video, the battery and paddle are attached to the radio and I use the back of the radio to hold my log. Very compact and very efficient. I certainly can't claim this as an original design since I coped it from Fred, KT5X. My antenna is a linked EFHW into an 81:1 transformer. The actual link connection design was inspired from Frank, K0JQZ.

January VHF Contest Plus SOTA
A view of Pikes Peak from Mt Herman.
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.
Bob K0NR using an HT to make contacts on 446.0 MHz FM.
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.
Freq Mode UTC Call Grid 146.52 FM 1900 KA0MWA DM79 146.52 FM 1902 N0AXK DM79 146.52 FM 1905 N0LP DM79 146.52 FM 1905 K0GPA DM79 146.52 FM 1905 WG0AT DM79 146.52 FM 1920 N0ISB DM78 146.52 FM 1923 N0LEA DN70 144.2 SSB 1932 WY7KY DN71 144.2 SSB 1935 K0ALE DM79 144.2 SSB 1938 AB0YM/R DM79 144.2 SSB 1939 KG0RP DN70 144.2 SSB 1940 WA7KYM DN71 144.2 SSB 1942 KC4YLV DM79 446.0 FM 1948 W3DHJ DM78 144.2 SSB 1949 WE7L DM79 144.2 SSB 1951 N0SP DM79 446.0 FM 2000 KE0HBW DM79
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!
73, Bob KØNR

SOTA Rig Reconfiguration
Activating SOTA's, if you do it regularly, is an iterative process. Of course the primary focus is to get to the top of whatever summit you might be tackling on a given day, but another part of the game is how you get there. Of course the right clothing to be comfortable in whatever conditions you face, the right pack to carry your gear and of course the right radio. But then, some of the fun begins. Not only the right radio, but how will I configure the radio to maximize my signal, be as light as possible and how to I package of this so I don't have radio gear all over the ground or digging in my pack to find the battery, paddle, etc.. I have activated 150+ summits and this is a continuous process.
Since I've retired, I've now have the opportunity to have continuous thoughts about things like this without the interference of work or schedule related thoughts, it's great. Consequently, I've had some time to give my rig configuration some thought. What I have done is not totally unique as I have gotten ideas from others and mixed them into my own concoction. I have the 3 Band MTR, with 17m, 20m and 30m. I chose these particular bands so that I would have flexibility on contest weekends. So below is my latest, not my last configuration.
As you can see I am using a backpacking cutting board as the foundation of the setup. I used a product called Scotch Extreme fastener to attache the LIPO battery and the Pico Paddle, it's sort of like Velcro but it snaps into place and is 10x stronger than velcro. I simply drilled holes (this board has seen several iterations as you can see the many holes), and used rubber bands to hold the radio in place. I may decide to use the fastener instead. The "Rite in the Rain" card is for logging. A nice neat package to pull out of the pack, hook up the antenna, plug in the power and off I go.
There are however a couple of further improvements.
You can see I've added a tethered pencil for logging and an optional Elecraft T1 tuner, if you have a non-resonant wire. I can fasten it to the board with either rubber bands or the Scotch fastener.
I've also added a protective cover for the MTR. It's made from sleeping pad foam and protects the face and switches on the MTR when getting jostled in your pack. On the backside of the cover I've cut out recesses where the switches are and added little magnets that are attracted to the four screws on the case. Thanks to Fred, KT5X for this idea.
So there you have it, a light, three band, package that is compact, light and ready to go. So until I reconfigure again.
