My homebrew CW/SSB receiver for 20m band based on NE612 chip.The crystals in the ladder filter are not perfectly matched. The tuning potentiometer is recycled and has mechanical flaws so I shoud hold it with my thumb while tuning. :-)Update:The schematic of this radio is not public at the moment, because it is not finished yet. But it is quite typical NE612 construction, so you can find several very similar (or even better) receivers on the net with this chip.
