[BC] Noisy Audio Chain

[Tom Dimeo]

Quite often WWII 720 leaves their carrier on all night. There 
is so much high frequency noise on the signal that I can hear 
it eight to ten kHz on either side of center. It sounds like 
there is a blank tape playing. There is also some sixty and I 
think one hundred twenty Hz hum on the signal.

Is it normal for an audio chain to be so noisy? I realize 
that the audio processing will bring up the noise but it is 
much louder than I'd think it should be.

My experience goes back to the sixties and I know what noise 
modulation like this would do to the modulator tubes of the 
transmitter, is it as hard on a solid state transmitter?


Just curious.

I've given up calling the station and telling them about the 
transmitter being left on. Shortly after the last time I 
called them one of the owners died.
