[Elecraft] Remoterig - Control K3 makes audio?

[David F. Reed]

Hopefully someone out there is running Remoterig with their K3s that has 
already been down this road...

I am in the process of debugging my setup, and have succeeded in getting 
the radios to communicate with each other properly.

I am stuck at the following problem (I am sure there will be others 
along the way as well):  when I am connected to the remote station, my 
controlling K3 produces background audio.  Naturally, I cannot use the 
volume control to do away with it, since that is controlling the volume 
to the speakers (from the remote K3).

Is there a more elegant solution than just plugging an unconnected plug 
into the headphone jack?

Thanks in advance & 73 de Dave, W5SV
