[Elecraft] K3 RX Ant - first try - nothing

[Jim Miller]

I have not tried to use Rx ant previously.  

K3 (sn 1442) Manual Rev D pf 43 - I have KXV3 and KAT3.  

Antenna connected to BNC on KXV3 and Rx ant selected on main receiver.  

No receive.  

If I connect same antenna to Ant 1 or Ant 2 - it works very well.

Is there a configuration setting to enable the receive antenna?

What am I missing?

 

It seems there was a decision to make when I assembled it that had to do
with antenna configuration and I cannot find it in the manual. Also it may
have been in a configuration I had before all the add in components were
available.  Which assembly component manual would that have been a part of?
Would that have anything to do with this problem?  Where can I find the
explanation?
