My standard SOTA setup is a Yaesu FT-90 compact VHF/UHF transceiver stuffed into a fanny pack with its Bioenno battery pack. The fanny pack is a pretty nice flyfishing pack that I position on the front side of me so I can easily see and operate the radio. I am usually holding the 2m or 70 cm Yagi antenna and talking on the microphone.

I’ve been looking for a way to clip the microphone onto the pack. Typically, what happens now is I drop the microphone and it gets banged up when it hits the rocky ground. I needed a way to easily hang it on the side of the pack. I recalled having an old cellphone belt clip that accepts the standard button on the back of a mobile microphone, but I couldn’t locate it. However, I did find one on Amazon.

I clipped it onto my fanny pack and the Yaesu microphone hangs quite nicely on it. This clip can be used for other applications…anywhere you want to hang a microphone onto a backpack, belt, or whatever. Depending on your station configuration, this may be useful for all kinds of portable operating: SOTA, POTA, and satellites.

The areas I worked in the contest

In this contest, I operated CW only, low power (100 watts) and no spotting assistance. I always avoid using spotting assistance as it hinders my goal of improving my CW. I found in the mornings I had a good path into the EU and as that closed down in the early afternoon the U.S. opened up.  By late afternoon South America was open to me. One of the highlight contacts was getting into Hawaii and I was also able to make numerous contacts into South America. 

Once it started to get dark the band for me closed down. In this contest, I did try running (calling CQ contest) but I found I was able to get better numbers with search and pounce. In most contests for me holding a frequency and calling CQ contest would always give me a good return but not in this contest. The 10m propagation for me had deep QSB and one moment a station was calling CQ and all of a sudden gone!

The final score

 Merry Christmas to all my blog readers

Hello and welcome to Episode #492 of Linux in the Ham Shack. In this short-topics episode, the hosts discuss Youth on the Air Camp for 2023, ham radio in local media, Open Source Hub, Hack Club, Asahi Linux, CatRadio and much more. Thank you for listening and have a wonderful week.

Who really uses the VHF and higher bands (>50 MHz) for Summits On The Air? Last year, I pulled some data from the SOTA database and provided some analysis.

Looking at VHF/UHF SOTA Data

Here is the short story:

Roughly 20% of the SOTA contacts worldwide are on VHF/UHF frequencies and about 90% of these are on 2m FM.

So that’s the information that is in the official SOTA database. For SOTA, I pretty much operate on the VHF/UHF bands so over time I’ve noticed that four types of operators use VHF/UHF for SOTA. Of course, this is based on my own observations, mostly in Colorado but also in other states.

Beginners

Many newer hams or new-to-SOTA hams just grab their handheld radio and go do a SOTA activation. This makes a lot of sense, assuming there is reasonable 2m FM simplex activity around. Summits that are within VHF range of large population areas usually work quite well. A Technician license is sufficient to have fun with this mode (both activating and chasing). If you are new to ham radio, like the outdoors, and have SOTA summits in your area, this is a fun activity to pursue!

HF+VHF Ops

Many SOTA activators are after longer distance contacts so they naturally gravitate to the HF bands. Some leave VHF behind, as they focus on HF operating. However, many SOTA activators and chasers keep a VHF radio in their toolkit, often treating it as an add-on to their HF activity. Sometimes the VHF radio becomes the fail-safe mode if things are not working well on the HF bands. Sometimes, I hear activators say something like “the HF gear was just not working for me today, so I had to use my HT to log four contacts.”

Non-SOTA Ops

There are quite a few hams out there on 2m FM that are not really focused on SOTA. They like to hang out on 2m FM simplex, especially 146.52 MHz, to chat with whoever comes along. In the backcountry, this may include hikers, snowshoers, skiers, 4WD enthusiasts, campers, etc. It also includes hams just hanging around the shack with a radio or scanner monitoring 2m FM. Announce that you are on top of a summit and these folks are happy to contact you.

VHF Enthusiasts

Finally, there are VHF/UHF enthusiasts that like the combination of higher frequencies and mountaintop operating. The effect of Height Above Average Terrain (HAAT) has a huge impact at these frequencies. A 5-watt handheld (HT) might be limited to a few miles on flat terrain, but from the top of a summit, the range extends dramatically (50 to 100 miles). Improve your station and 200-to-300-mile contacts are achievable. Most of this action is still on 2m FM but adding in additional bands (70 cm, 23 cm) and modes (CW, SSB) provides another challenge. Chasers are included in this category as well…there are VHF/UHF enthusiasts that are challenged by working distant summits from home.

Summary

These are the four categories of folks I usually encounter on the VHF/UHF bands when doing SOTA. Do these match your experience? What did I miss?
