When the transmitter is turned on, one of the internal generators in the 
aircraft immediately turns off.
   The generator is a 3 phase 115 VAC 400 Hz model that uses an internal 
permanant magnetic generator at
40 volts AC 800 Hz, that is in turn regulated to control the field of 
the generator.  This is controlled
by a Supervisory Control Panel that controls the field and also monitors 
for over/under voltage and frequency.

Clearly the Supervisory Control Panel is being impacted by RFI thus 
shutting the generator down.

   Test the situation with an appropriate test load in place of the 
antenna.  Possibly with an appropriate test load in place of the antenna 
and feedline.
