Hi, Jamie: First, troubleshooting, voltage tables, etc., are in the Owner's Manual. Their location is called out in the assembly manual on page 53: Final Test and Alignment, in case you run into a problem like this.
Be sure you incorporated Errata C-4 into the Owner's Manual. It includes an updated schematic diagram for the XV50 that shows R39 and new voltage tables for troubleshooting. My first guess would be that you left jumper W1 out. That would open the bias circuit to the RF power amplifier module. It should have been installed as the second step on page 39 (in the assembly manual) of the building procedure.

Before keying, I get 7 mV; after keying, no matter what position R39 is in, I get only 12 mV. There is no troubleshooting section in the manual. Could someone point me in the right direction ?
