[Elecraft] KRX3 + RX antenna

[Franki ON5ZO]

Group, forgive me if this has come up before (which it has has) but contest 
fever kicks in.
It seems that for the first time I have a "kinda" RX-antenna (solder still 
hot!).

If I want to listen to both the 80m vertical and the RX loop at the same 
time, is this all I need to do:
- set both receivers to the same frequency
- connect RX antenna to "AUX RF BNC"
- set KRX3 to "Ant = BNC" in the config menu

Is that all there is to it?
