Winter SOTA Activation of Kaufman Ridge North
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.

Chinese Kit Invasion
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.

January VHF Contest Plus SOTA
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.
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!

SOTA Rig Reconfiguration
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.
