[Elecraft] K3S receive antenna

[Don Wilhelm]

Leroy,

The answer is "yes", but how to do it depends on your K3S physical 
configuration.

If you only have the main receiver (no subRX), you can transmit on ANT1 
or ANT2, and connect a receive only antenna to the ANT IN BNC connector 
in the rear (set of 5 BNC jacks).
Select RX ANT.

If you have the SubRX installed, things get a bit more complicated, and 
it depends partly on how you have the subRX AUX input connected and 
whether the subRX is set to share the antenna with the main or whether 
it is set to use its AUX input.

If the subRX AUX input TMP cable is connected to the TMP jack on the 
KAT3, then the AUX input for the subRX will be from the non-transmit 
antenna - in other words, if the main is set to transmit on ANT1, the 
SubRX will listen to ANT2 (assuming the subRX is set to use its AUX input).
OTOH, if the AUX input for the SubRX is connected to the BNC AUX input, 
then a receive antenna can be connected to the BNC AUX jack and the 
subRX will listen to that RX antenna when the subRX is set to use its 
AUX input.
