Kevin,
Please re-check.
The pin numbers are not marked on the board or on the module.
According to the voltage chart, pin 1 is the output pin and pin 4 is
closest to U6.
If you have 13.6 volts on pin 3, you have a error somewhere - that pin
is fed from the output of the 5 volt regulator U3.

Hi Folks,
I have a XV 50 that has no output. Nothing is showing on my Bird meter but
the LEDS do light up across the front of the transverter when I whistle into
the mic. It appears to receive ok.
Measurements taken:
U7 Pin 2- 13.6v receive, Pin 3- 13.6v ( should be 3.5 - 4.5) transmit
U 3 Input - 0v receive( ok), 13.5v transmit( within limits?)
Output- 0v receive (ok), 9v transmit ( should be 5v)
U 6 Output- 0v receive(ok), 1.7v transmit ( to K2 relay) and (5v to Z3)
