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?

The post Who Does VHF SOTA? appeared first on The KØNR Radio Site.

We have been having rain a lot out this way and today it was overcast and showers were not forecast. I decided it was time to go out for a walk and get some fresh air. The temperature was plus 2C with a brisk wind. As I was getting back home it started to snow but not enough for any to stay on the ground but the days of that are just around the corner. Once home I poured myself a cup of decaf coffee and headed to the radio room. 

I am not sure why but I thought it would be nice to check the POTA (parks on the air) website and look over the spots. I have done this in the past and was not able to hear any of the park activators. I am very glad I did as the POTA propagation gods were smiling on me. On 20m I tuned in to each mentioned spot on the POTA website and low and behold I was able to hear the park activator. Their signals varied from 229 to 599. I had a great time and it's only a short exchange of information for the contact as they are racking up contacts.
The contacts I made on 20m:
KQ4CW
KD8IE
N1QD
KD3D
KG8CO
K9ABR
One contact on 40m
KC1MXB
