[Elecraft] [K3] quick diversity set up question

[David F. Reed]

Sometimes I manage to confuse myself with simple things; this seems to 
be such a case...

I am practicing setting up for the 160 M. Contest (and of course doing 
some DXing meanwhile).

I want to be using diversity reception, with a dipole on one antenna, 
and a vertical on the other.  I want to be able to (single button push) 
select which antenna I am transmitting on, either split or not, all the 
while keeping diversity reception going on those two antennas.

I would prefer using ANT1 and ANT2 as opposed to other (AUX) RX antenna 
inputs, solely for convenience of the UHF connectors.

My confusion?

I cannot figure out how to do it, or if I have succeeded in doing it 
correctly (like, which antenna is on the sub).  I think after that, it 
is just a question of engaging diversity reception mode, and split, with 
the additional button press while tuning VFO B for the transmit 
frequency and press again?

Thanks & 73 de Dave, W5SV
