All N1MM logger needs to do is read the mic gain (MG;), store 
the value and issue an MG000; command to mute the mic.  When 
the message is over, issue MG##; with the stored value.  It's 
not brain surgery. 

However, routing the microphone into the soundcard and the 
soundcard output to the K3 mic input is far preferable as 
it allows N1MM Logger (or WriteLog, WinTest, etc.) to handle 
muting of the microphone while the wave file is running 
automatically without transceiver commands or contention 
over line vs. mic priority.  

It's not even difficult to configure mic PTT or footswitch 
to serve as a "dump" switch which cancels the wave file 
in midstream and reconnects the microphone.
