High Performance Regenerative Receiver
very effective input attenuator that serves as an RF GAIN control. As be- fore, the RF stage is inductively coupled to the detector via Ll. This maximizes signal transfer to the de- tector without loading it down. JFET Q2 operates as a tickler feedback or Armstrong regenerative detector cir- cuit. This receiver uses a 2N4416
