  Where is the C3 of 2880? Which document should I see?

  If you are seeing this image of G3PHO's stite,

  I do not know the value of C3. I have no equipments to measure it.
But I think it will be 1,000pF or more. Its purpose might be just a
DC-blocking of RF output.
  I checked some documents of preamp that I have, ans most of them
said that the output DC-blocking cap should bw 1,000-2,200pF.

  73 de Yoshi.
