[Elecraft] K3 Second receiver question

[Jerry Flanders]

Those of you who have the second receiver working:

Does the second receiver mute when you transmit on the K3, or is it 
still working so you might possibly copy signals on it while actually 
key-down?

I know this is a difficult engineering challenge, and, IIRC, other 
radios of the past with two receivers simply mute the second on transmit.
