Nov 22, 2011

EMRFD said that  A SA  is just a special receiver, with auto scan it's band. I have one Regen Receiver, Aamazing Regen Receiver,  and a ramp generator Versatile ramp generator. when i replace Receiver's tune Cap, plus a diode to audio output,  i get a Demo SA.

What's on the Oscillascope? look at this Video: (sweep the 4Mhz crystal, strange, but it's "like" a SA anyway.)
