2n2222 Regenerative Receiver. Its easy to build and offers excellent performance. A three transistor receiver the fet as a regenerative detector by walter f.
The renerative receiver is extremely sensitive to weak signals but it is more complicated than a trf receiver. 2n2222 regenerative receiver the radio works great. Here is a preliminary schematic.
Lange wiyds vex in this age of crowded hands and sophis ticated communications systems there is room for the lowly regenerative receiver.
Most of the current is drawn by the audio power amplifier about 5ma when idle and a max of about 8ma in operation. Raycharlesring rf this design uses junk box 2n2222a or 2n3904 transistors. Regenerative receivers provide a surprising level of performance with only a handful of components. All coils are designed using an inch diameter pvc pipe using 20 gauge insulated hookup wire l1 require 6 turns and l2 require 14 turns.
