Apologies, as I'm sure this has been addressed before. I'm new to CW, just finishing CWOPS Beginner, and am looking to set up my K3S/P3 for best use on CW. Might there be a guide that I can start with? My K3S has filters down to 500Hz. Thanks for the help! Bret/N4SRN -- Sent from: http://elecraft.365791.n2.nabble.com/
