Re: Trio TR2200GX RX Oscillator
It looks to me like a mistake, if C56, went to the C57 on the emitter, it would then be a normal Colpitts Osc. (The clue is the lowish values of those two caps) I wonder if the schematic diagram or whole design was wrong by mistake?
Without that connection I would hope to see a small capacitor (1-3 pF) from C to E to maintain the feedback loop.
