Used with a series of 150w airborne jammers - AN/ART-6 through -11 - 
that covered German tank communication frequencies from 20-75MHz.  The 
design was essentially a square wave power oscillator (pair of 35TG's) 
modulated by a fan driven split stator tank capacitor.  Needless to say 
it was rather rich in harmonics that provided a compatibility problem 
for other avionics, thus the low pass filter...  I made some 
measurements on one a long while back - will try to dig them out.

Best 73,
Mike
