RC,
I assume you pulled the KXAT1 out - did you remember to install the jumper?
There is little that you could have done by transmitting that should harm
the receiver, the paths are separate except through the LPF.
For your KXAT1 problem, the usual answer when you have trouble nulling the
bridge is to first look at the wattmeter bifilar transformer, and check the
orientation of the diodes. Also check the soldering for the inductors and
capacitors, and check for solder bridges across the relay pins and
unsoldered relay pins.
