Use K3 receiver with separate Transmitter?

[Bill K4BX]

Would it be possible to use the K3 for a receiver only when using a
separate transmitter? Would like to use the K3 to receiver with a
separate AM transmitter.

thanks,
K4BX

Yes.  

There is no direct way to mute the K3. The workaround is to place the K3 transmitter in TEST.  Use contacts on the T/R relay to close the PTT line, which will mute the K3 receiver. It will actually be in transmit, but won't since it's in TEST.

Of course, you also need to provide antenna switching external to the K3, as you would with any other BA receiver.

Bill,

Yes, that should be quite possible, but you will have to arrange for
external T/R switching.
To mute the K3 during transmit, I would suggest putting the K3 into TX
test and applying the external T/R switching "mute" signal to the K3 PTT
input.  You should be able to use either the normal K3 antenna input or
the RX Ant input for receive.
