Simple regen RX


Quite often I get asked how simple can you make a receiver that gives useful results. 

Of course the simplest of all is a crystal set that does not even need a battery. 

The simplest circuit that really works well is probably the one shown. I even adapted this into a 1 FET 80m transceiver. The RX works well on AM, SSB and CW.  By changing the tuned circuit, it will work on different bands. As a transceiver my main issue was netting the RX onto the TX frequency.

There are plenty of similar circuits on the Internet.
