TRF  RECEIVER.


trf 1

Been busy working on some  simple  shortwave receivers  over the past few month's  one fore for the 80 meter band , SSB  Coverage .

But here we have a  TRF  Receiver with gives  good results  for the 40 meter ham band SSB.

Varicap Tune

Here  one can use a Varicap  fore tuning witch is far cheaper than using a   Air spaced cap.

Also  one can change  the  100uh inductor  for a smaller  value down to say 3.3uh.
