Recently changed to the Elecraft MH2 mic on my K3 (SN 4052). When I tried to set-up the mic for SSB transmit, I noted no indication in the ALC graphic when I keyed the mic. Tried it at a mic setting of 20 and again at 40. Mic is hooked to K3 with front panel mic input. Any ideas? 73s de Dave KJ6CBS
