[Elecraft] K3 SUB-RX audio

[evert at pa2kw.com]

Setup was: 

*	K3 with SUB-RX and MicroHam MKII
*	ANT 1 = TX antenna, RX-ANT (BNC) = Receive antenna.

 

When using the SUB-RX (I think even in Diversity mode), with JTDX I was able to “listen” to the Left audio channel which was the SUB-RX (receive antenna)

 

A while ago I installed the KIO3B board. All seems to work fine but….

Whatever I try to change, I’m not able to “listen” to the SUB-RX with JTDX anymore.

I do hear both receivers in my headphone Main = Right ear, Sub = Left ear.

Is the Audio Codec signal a MONO channel or is it a setting in the K3 I didn’t think of?

 

Any help appreciated.
