Shortwave Regenerative Receiver

regen2regen1This project is a great way for beginning builders to hone their skills at circuit construction. The receiver plans were originally printed in a September 2000 article in QST. I built mine from scratch, not on a printed circuit board, with no ill effects due to strange parts placement. The author provides very good advice about the audio/volume and regeneration controls placement and hookup (by being careful, no shielded audio cables are necessary). Since I used a large value tuning capacitor from my junk box, I added the optional fine tuning control to add better selectivity to my receiver, which is very helpful when tuning. By following the author’s recommendations about how to assemble the receiver the average builder should have no problems with this project. When in doubt, the provided voltages on the schematic are a handy way to test your completed project.
