Discrete devices minimize distortion and eliminate fuzziness while listening to low-level CW signals in communication receiver covering 1.8-2 MHz. RC active bandpass filter peaked at 800 Hz improves S/N ratio for weak signals. Adiust BFO of receiver to 800 Hz.Two-part article gives all other circuits of recelver,－D.DeMaw,His Eminence-the Receivel,OST, Part 2-July 1976,p 14－17(Part 1-June 1976,p 27－30),
