RF Amp

A project log for PolyMorph Receiver

A minimalist direct conversion radio receiver. 4 general purpose transistors and a Polyakov 2 diode mixer.

Added another common emitter amp, this time for incoming RF.

The performance boost is immense, small signals are much easier to hear and large ones boom (CW and SSB).

Unwanted outward RF leakage seems to have been greatly reduced.

I use an atennuator pot to better hear stations, diminish AM breakthrough and generally control audio volume.

Updated schematic and pictures coming soon!
