[Amps] caps across rectifier diodes

[ToddRoberts2001 at aol.com]

Back when I first started building some low power transmitters
I always seemed to notice a slight hum or buzz superimposed on the
carrier until I bypassed the power supply diodes with .01 caps across
each diode. I also seemed to notice RF getting into the AC house
wiring that was also cured by adding .01 caps across each rectifier.
 
Likewise I have run across some solid state and tube receivers that had a  
buzz
superimposed on reception especially at lower frequencies. The buzz  was
cured when .01 caps were added across the power supply diodes.
