This little regenerative rcvr was built with parts from the junk box. The sound quality is absolutely amazing, but my construction needs a little refining. With the coil I made, and the capacitors I used, it sits in the 49m band. The antenna is a 36" piece of wire, and considering the parts count, the signals this rcvr sucks in is incredible. The big capacitor makes tuning difficult, so I went back to a smaller one, which gives much better selectivity. I plan to build a more elaborate regen in the future.

This rcvr was built from an article (pdf) by Charles Kitchen, in QST.
