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.

73,
