Sorry for too early sending of my previous message.  

I continue....

My FT-817 was modified this way on BNC output injecting +5V TX through a 4.7kR and a 1nF in order to prevent DC to enter receiver.

>>> 3) same question regarding BNC output as 28 or 50 MHz could be also used as IF for 70 / 23 cm transverters .
>> 
>> Sorry, there's no provision for DC at the BNC output of the KX3.

May be available in the future?
