[AMRadio] series modulation...???

  Hi Mike: Well, I went back to the AM Window "tech" section again myself
  tonite and looked at the circuits (they added some when I was not looking).

  I didnt see anything there that was a single tube, modulated or not.
  Maybe I got lost somewhere or didnt see part of the post?? I agree that
  a single tube that is modulated is a modulated oscillator, HI. Only
  thing is most folks think of them as modulated oscillators such as were
  used in 5 (not 6) Meter rigs. Not suitable for HF but sure wouldnt
  crab about hearing one on 2 meters and up here!!

  73 es goodnight , Charlie K0NG.
