[Elecraft] KRX3 antenna routing

[Chris G3SJJ]

Whilst I am waiting for shipping notification of my KRX3, I have a 
question on routing.

I have a specific contest application coming up where we will be using 
SR2O. The idea is for the 2nd op to be monitoring a band other than the 
Run band. We are only allowed one antenna and have designed it such that 
the KAT3 will handle all the impedance presented on the various bands. I 
had hoped that the K3/KAT3/KXV3/KR3X antenna routing would allow us to 
connect the 2nd rx directly to the antenna
 and not via the ATU. Studying the manual I can't see how that can be 
done. Can anyone confirm this?

If not, I can make up a small relay box which takes a feed off the 
antenna input to Ant 1 socket and feeds it to Aux RF on receive and 
grounds Aux RF on transmit and I can switch it via the PA PTT switch on 
my mHam Keyer. An internal switching solution would be more sophisticated!
