Do you have transformers on both the audio going from rig->computer AND computer->rig?
Is there a ground connection between your radio and the computer? There shouldn't be. Do you have a communication cable going between the rig and the computer? You might try dialing in a 'noisy' frequency by hand and then disconnecting the com cable to see if that makes a difference. What kind of rig interface are you using?
