[TenTec] CW note

[WA3FIY]

Since not all signals have this characteristic, it is possible that you 
are hearing phase noise on the transmitted signal.   Some transceivers 
are noiser than others and narrow bandwidth filters tend to 
emphasize phase noise, especially if they have sharp skirts.

Listen to a crystal controlled rig or one of the non-synthesized rigs 
like a Corsair, or Omni D or Delta or Triton or ............well, you get the 
picture.   If you do not notice the fuzziness on those signals, you can 
be pretty sure your rig is OK.   Of course, if you rig is a Paragon 
Pegasus or Jupiter, you will have a certain amount of phase noise in 
your receiver.   But since you say "...not all received signals
> display the condition...", that would tend to rule out noise on your 
end.
