High Performance Regenerative Receiver

resistor R5 to the audio filters. R5 isolates Cll and C 12 from R4 and C8 in the detector's source; otherwise, the detector may break into superregen- eration. This can occur with high lev- els of RF feedback when a long RC time constant is used in the detector circuit. A large increase in either R3 or C5 Ir_ would produce the same effect. I sus-
