Homemade HAM Radio CW/SSB receiver for 20m - YouTube


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. :-) Update2: For all, who would like to receive the schematics and PCB, please send me a PM with your e-mail address. Update: Because there are lot of requests, there is the schematics of this receiver: https://twitter.com/BalageJ/status/216531997563174913/photo/1
