Simple Three Bands Regenerative Receiver

 

 

L3 should have 15- micro Henry. This one contains 14- turns of the enamel wire in diameter 0.8- mm (20- AWG). Winding is turn to turn. L2 should have 15- micro Henry. The inductor contains 40- turns of the enamel wire in diameter 0.3- mm (29- AWG). Winding spread in 1-1/2 layer. L1 has 160- micro Henry of inductance. It was used ready- made surplus inductor. As I have noticed the schematic works with practically any inductors. At first I would like to make the inductors on one form but later I gave up the idea because I cannot trim the inductance.

 

It is used a variable capacitor (unknown made) with build- in vernier. Loudspeaker is used from an old phone base SENAO. Switches S1 and S2 is a three- positions toggle switch. VT1, VT2, VT3 are small power transistors. Gain is not less the 100. F is not less the 100- MHz.
