[Elecraft] Diversity / aux RX problem

[Don Wilhelm]

Tony,

Where is your subRX antenna AUX input connected?  To the BNC jack below 
the 2 SO-239s or to the non-transmit antenna?

Once you know that, use BSET to changel the subRX input to AUX

If you do not know which antenna connector is connected to the SubRX AUX 
input, you can find out physically by removing the top cover and 
following the TMP cable.  If it is connected to the KAT3 then it is the 
non-transmit antenna, but if connected to the BNC jack, then that is the 
jack that is connected.
You might be able to determine it without removing the top cover - just 
set the subRX to use the AUX input and plug the antenna into each jack 
one at a time.  When you hear band noise or signals, that is the one 
connected.
