Interesting article in May Electric Radio regarding the adding of an audio
discharge resistor in postwar receiver detector circuits to allow for what
they term "full audio recovery" during both portions of the audio cycle, and
as a result, up to 50% reduction in harmonic distortion.
The example given is adding a 91K resisor across C24C in the Halli S-38.
I wonder if it'd be of any value in my SX28A: looks like C37 is the diode
load bypass cap, but I see R25 in there bridging the cap already. Any
opinions?
Thanks, Joe W1GFH/6
