[Elecraft] K3 - macro needed for RX mute

[Bill W2BLC]

I need a toggle style macro to mute/unmute the RX audio on my K3.

When I get a phone call or someone comes in the radio room it is often 
necessary that I turn the audio down on the K3. Currently I use a button 
for setting AG000 - which effectively kills the RX audio - however, I 
must manually reset the audio with the AF gain pot.

It would be much easier to push a toggle for mute and another to push to 
return to the original AF gain setting.

I use a Pigknob with programmable buttons for rig control - including VFO.

Note: I feed my speakers from the rear of the K3 and never use phones.

Thanks,
