KRX3 always uses antenna from main RX

[Ignacy]

I tried diversity today and something is wrong. KRX3 input (BNC) is not working and KRX3 receives always receives signals from the main RX.

In KRX3 menu, Ant=bnc

Definitely the diversity was working a couple of month ago. I upgraded to the newest beta, and no change.  

Any idea what might have happened?

Please ignore. After a few turning of and on, reloading N1MM, etc., KRX3 is working well again. Have no idea why BNC input was not working.

N1MM has the capability to turn the KRX3 on and off depending on spots, and
can undo what you last did on the front panel. Doing a hold on RX ANT on
the front panel will toggle the KRX3 between MAIN and whatever is connected
to the AUX input. The latter could either be the BNC or the SO239 not in
use by the TX, depending on where the KRX3 aux input was connected at
assembly.

Ignacy,

Which TMP connector is plugged into your subRX AUX input.
Is it the BNC connector or the TMP cable from the KAT3?
If it is the BNC connector, then the BNC jack should work - that is the
plugging used for the K3 (K3S) factory build units.
If however, you have the TMP cable from the KAT3 plugged in, the subRX
will use the non-transmit SO-239 jack when the subRX is set to AUX input.

It makes no difference what the menu says, you must set the menu
according to how the K3 is physically connected, so if you do not have
the BNC connector plugged to the subRX AUX input, you will not have any
input from the BNC connector.  The "magic" is all in the physical setup,
and the menu must be set according to that.

This must have been N1MM+ or I pressed RX ANT too long. I forgot that RX hold has a functionality with SUB on, switching between AUX and MAIN. It is easy to be fooled.
Good that this group exists.
