[TenTec] Jupiter on CW

[Steve N4LQ]

The raspy sound you hear is phase noise transmitted by the Jupiter and it is 
present in the sidebands. The noise is much weaker than the carrier and 
other stations will not hear it unless the signal is rather strong.
Selective fading will cause the noise to appear to come and go. Selective 
fading can null out the carrier and allow the sidebands to pass making you 
think the noise is coming and going while actually it's there all the time.
