To ask the question another way ... Can the K3's mic connector be configured in the same manner as the K2's to suit different schemes? I didn't see this dealt with in the FAQ list. I have several Icom-configured mics ... including a Heil HS ... and my K2's set up for them. Obviously, I'd like to configure the K3 to accept them. 73! Ken Kopp - K0PP k0pp at arrl.net
