What is this?


This dates from 2011 and I have not a clue what this is. There is an SBL mixer and it looks like some sort of direct conversion RX, but I have no idea what it is! I obviously was breadboarding something. I guess I could trace the circuit.

    Looking at the picture and making a quick circuit in my head, it does look like a direct conversion receiver.

    Can't quite read the crystal frequency, that would give a clue what band it was used for.
