A couple of months ago I built a Steve Weber 'Slop Bucket' 20 meter Transceiver that is SSB/CW. It uses a 74HC4053, a triple DPDT analog switch driving some transistors for T/R switching. It is sweet, no clicking at all, just nice and quiet. That radio is a pleasure to use except for the hissy LM386. I guess I can't have it all my way.
