Terry,
I believe Lyle answered that already.
I do not believe that muting the mic when PTT is asserted from the
RS-232 input is a good idea. Many logging programs use the RS-232
signals to activate transmit.
Some mics (mostly handhelds) are muted until their PTT switch is
depressed, but desk mics are usually wired with live AF signals.

Ed raises a good question, with the built in isolation transformers in the K3, computer audio into the Line in now sounds great. With the mic+line enabled to allow the computer to call CQ's and a live mic connected to either the FPL or RPL, is there a way to mute the "live" mic while audio comes in the LINE in? Or does the noise gate only affect the mic amp stages?
I guess the only way to do this would be if the rig is keyed via RTS or DTR,
only the line in is active, but if keyed via vox or PTT, the mic is active???
Thanks,
