[Elecraft] Mute Question

[Dave Hawes]

In our Multi-Op station, we use a lot of K3s, many times with two on the same 
band, and sometimes with two on the SAME FREQUENCY.

N1MM Logger provides for a very convenient "callsign stacking" feature 
allowing an assisting operator to listen to the running station's pileup and 
suggest callsigns.  However, it is very uncomfortable for the assist operator's 
ears when the run station transmits, since the assisting op's radio is not 
muted in any way.  We are hopeful that someone has tackled this problem, 
and has a solution.

Is there a way to reduce the audio on an separate K3 when the running K3 
goes into TX?  We wouldn't want the audio turned off completely.  An 
adjustable reduction in audio level would be preferred, so that the assisting 
operator can at least hear what the run station is sending (or saying).

Thanks.
