Karl the answer is very simple from my point of view and I explained it just over 2 years ago…
We’re on the way to the next Solar Maximum and having missed some in the past when I was less HF oriented then I don’t want to miss any more. So for some time I have been concentrating on 28/24/21MHz first. It’s Winter up here and is noticeably colder and darker than down in Kernow. That means there is less time for activations. I want the higher HF bands and so the lower HF bands get missed out. It bugs me because I cannot work my long time chasers on the lower bands.
I was very pleased that Paul MM0SNA did 20 and 40m last Sunday when we were out as it meant “locals” could work the summit whilst I went to the dizzying heights of 28.062, 24.906 and 21.062 I’ve not seen Simon GM4JXP out for a while, I think he has injured his knee, Fraser has been in foreign parts and Gavin GM0GAV has not been out much (I guess he’s work busy). There are some newer GM activators in recent times, 2M0PVP and MM7MOX to name 2 local to me. They too may be playing on the higher bands however.
