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.
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.
