[Elecraft] K3 Monitor

[Don Wilhelm]

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.

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?
