I'm enjoying listening to an AM roundtable on 3885 tonight. With syncAM I don't miss a single word! I leave the CWT on and the K3 automatically corrects frequency as each OP takes his turn. Thanks Elecraft! Can you explain the blinking S? I assume it blinks until the PLL locks with the carrier. I see it go off/on at times. Maybe the station is drifting or there's QRN? What should we be looking for?
