I hooked up the serial data port on my Paragon II to my computer for 
logging of the frequency. There is a buzzing noise in the 
speaker/headphones with every data string. The volume of the noise does 
not depend on the band in use, whether an antenna or a terminator is 
connected, the mode or band. The only controls on the rig that do affect 
the noise are the audio gain and the tone controls. Seems like the noise 
is getting into the audio stages, maybe through a power supply common to 
both the RS-232 board and the audio stages. Have any of you experienced 
anything like this with a Paragon or Paragon II? It never happened with 
my Omni VI.
