[Elecraft] K3 - KRX3 Aux Ant Indicator

[Alan Sewell N5NA]

  I just installed my KRX3 a few days ago and am still figuring out how 
it all works.

I don't understand how to see which antenna the sub receiver is using 
without having to select BSET or press and hold the RX ANT to select 
MAIN or AUX.

The manual says "When MAIN is in effect, the 1-2 and RX icons show which 
antenna the sub is sharing with the main receiver. When AUX is in 
effect, these icons will all be off (if CONFIG:KRX3 is set for 
ANT=BNC)"  However, this is only true if BSET is activated.  When BSET 
is not activated I don't see any indication of the sub's antenna selection.

What am I missing?  Any help is appreciated.
