I’m not much of a contester (not any kind, in fact) but this weekend is one of the biggest: the CQWW SSB Contest. Expect the bands to be completely awash with chatter from 0:00 UTC October 29th through 23:59UTC October 30th. I doubt I’ll do much, other than maybe hookup my SDR-IQ to scan around some of the higher bands like 17, 15 and 10m to see what’s up.
