Brian,
Yes, you can separate the two halves and use only the Control Board.
Before you separate them, make certain ANT1 is selected - then power off
and separate them. Put a long jumper between J4 pin 2 and J6 pin 15
(that is next to the last pins on both ends).
If you still cannot balance the wattmeter in that configuration, you
most likely problem is with T1 - it must be EXACTLY like shown in the
manual diagram including the winding direction, and the leads must be in
the correct holes.
If the tests go OK without the L-C section, suspect an unsoldered relay
pin on the L-C board.
You will have the repeat the bridge null adjustment once the L-C section
is back in place to account for any residual reactance.

Built a KAT2 and all went well but no response at the first test. Question:
can I separate the two halves and remove the L-C board and still power the KAT2
for trouble shooting? Should the processor board still respond? Any tips?
