As I think out loud, here are the thoughts that some to my mind…
My personal experience of activating the LD region is that there seem to be plenty of chasers on 2m FM.
Personally I’ve never tried activating 70cm but I suspect that this would be close to impossible as I don’t know many people that scan the 70cm simplex channels or monitor the calling channel. Then again, it might happen if you spotted yourself on the SOTA website and enough locals happened to see the spot.
Virtually all of my Lake District activations have been completed using 2m FM. Sometimes I take a small mast with me, but most of the time have been just a handheld with the stock rubber antenna. It’s rare that I fail to get the required 4 contacts to qualify the summit in the Lake District, especially at busy times (like weekends).
As for CW, which is specifically what your question was about:-
I make the assumption that many of the regular chasers that come up on 2m FM or SSB would also be able to run CW on 2m if they saw your spot on the SOTA website.
This assumes of course that they know CW. There are plenty of people like me that both chase & activate on FM & SSB only, and cannot do CW. Please don’t forget us when activating!!!
My presumption would therefore be that it might be viable if you self spot (and maybe alert in advance to give people some pre-warning).I have done activations (on both HF & 2m) where i haven’t spotted or alerted and somebody has heard me and put a spot on the website for me. However I wouldn’t bank on that if using 2m CW.
Unfortunately I’m not proficient enough in CW to try it. I only just started the extremely long and frustrating process of learning CW about a week ago, so have a very long way to go before I’m proficient enough to actually test this theory.
Would be very interested to know how you get on when you do move to the Lake District?
