When you look back on the peaks of solar cycles, I find that some of the memories usually feature 28MHz. Last cycle I spent loads of time on 28MHz CW working across the US and beyond from a tiny garden in Windsor, with a stealth wire antenna! The cycle before that, I remember listening to mobiles driving around Tokyo on 29MHz FM on my converted CB set with a small antenna in the loft.
I wonder what this cycle's memories will be? Maybe some of the low power WSPR and JT65A. But this evening, driving home would be a contender. The KQ2H repeater was end stop on the Anytone and absolutely jammed with people trying to access it. After a couple of abortive attempts to put a call through, I sat back and listened.
6Y5SJ was working into the UK and Germany. A mobile in London was working a fixed station in Essex- over a path of 7000 miles or so! But what was brilliant was listening to (I think - this is from memory) K2SLJ/P using a UHF portable working another portable in New York through a UHF link. One of them was using 1W from a Baofeng UV-3R. How cool that their signals are crossing the Atlantic and beyond.
