[Elecraft] [K3, k3S] for the Sub Receiver

Leroy,

The subRX will normally use the transmit antenna, be that ANT1 or ANT2 - 
there is a 3 dB splitter inserted to feed both the main and the subRX.

Now --- *if* (and only if) you select the AUX antenna for the subRX, 
then the antenna connection that you have plugged into the rear of the 
subRX will be used - whether that be the BNC connector or the 
non-transmit antenna.

So decide on which TMP cable you want to connect to the subRX AUX ANT input.
If you want it to be a receiving antenna, then I think it is best to 
connect the BNC jack.
If instead you have two antennas, both of which are transmit capable, 
then you may want to connect the subRX AUX ANT to the KAT3.  When the 
subRX AUX antenna is selected, receive for the subRX will be from the 
non-transmit antenna - in other words, if you select ANT1, the subRX 
will use ANT2 - and vice-versa.

73,
