Early Solid State Ham Project. These are relatively simple radios to build and they can receive any type of modulation, from AM to Single Sideband, to FM. So in a real, though attenuated sense the regen had survived World War Two. Most of the above description might apply directly to a regen using FETs. The volume control and onoff switch can be seen to the right (rear). But solid state made things small, and cheap. Solid state regenerative receiver. I think a time has come to have, perhaps, a similar organisation to the crystal set society, only for regens. It is certainly not "just another regenerative receiver" Unlike most solid state regenerative receivers, this one does not need a low impedance winding on the aerial coil to feed the first transistor. The set is .
