This Sunday, between 1400 and 1759 it's one of the biggest domestic HF contests of the year; RSGB's Affiliated Societies Contest. If you're a member of a club, you should try and get a team together. Either way, try and get on 80m CW tomorrow afternoon and make as many contacts as you have time for.
The exchange is a simple format: RST and Serial Number. See the full rules here
I'll certainly try and get on for a few minutes at least.
