Excellent! Thanks to Dave, Joe and Don for the useful information. The
K3 is now on the bench and I'll start work soon. It most likely is D5 on
the KXV3.
Thank y'all for the quick response.

Randy,
I suggest you contact K3support - they can likely give you a small
number of probable failure points. That will allow you to choose
field repair or send it to Watsonville.

Randy,
Is the main RX dead all the time (when using only Main RX - Sub RX
off)?
Two quick things to check ...
1) if the Main RX is dead all the time and you have KXV3/A/B boards
in each rig, swap them. If the problem moves with the KXV3, the
problem is most likely D5.
2) If the Main RX works if the Sub RX is off and you have KRX3 in
in each rig, swap the SUB IN boards. This eliminates an issue
with T1 (the splitter) and D1/D2 T/R switch PIN Diodes.
The first thing to check is the KXV3 ... If you don't have a second
KXV3, check the schematics for bypassing the potentially defective
one (J66, pins 13 & 15 and pins 8 & 10).

If you have the KXV3 installed, it is probably D5. I checked the
Mouser part number for the heavy-duty replacement, and it's still good.
