More of that jamming action from William Crowell (ex-W6WBJ) or his friends ("Billy's Children") on the WARFA (Western Amateur Radio Friendship Association) relay frequency at 3890 kHz. This crap ran from 8:02 to 8:13pm last Tuesday (6-15-21). The main frequency was also being jammed at the same time. Recorded off the KFS WebSDR.
