Philmore regenerative receiver

WebbThe 3 Transistor Short Wave Radio illustrated in this article is a regenerative receiver design. The Superheterodyne receiver uses many of the same components as the TRF and Regenerative receivers but adds special oscillator and amplifier circuits that make tuning into the desired station very easy. Webbdebugging of homebrew regenerative receivers (ER No. 134, June, 2000). After reading this, one wonders how 1930s constructors were able to get the darned things working at all! Another excellent source of information is author Bob Dennison, W2HBE (for example, see ER No. 137, October, 2000) who has written extensively on the

Webb18 sep. 2012 · For CW (Morse code) reception, set the regeneration level just into oscillation. This will give you the highest sensitivity and selectivity. Tune the receiver to either side of the carrier to get the desired beat note. The CW beat note should be very stable, if it varies at all, simply increase the regeneration level.
