The March 1989 _RF Design_ has an article called "A Microwave Oven
to Amateur TV Transmitter Conversion". No, he's not kidding.
It's a microwave oven with the magnetron cathode current modulated
by a pair of 6JE6s, a power FET and an opamp, producing 250 watts of
FM video in the amateur 2.39-2.45 GHz band. A modified MDS TV
downconverter (like terrestrial HBO receivers) or modified TVRO unit
is used to receive. The modulator sits where the food used to go.
Obviously not one to fool around with if you don't know what you're
doing, plus a microwave spectrum analyzer appears to be necessary,
but it is the most original project I've seen in awhile.
