This may be a "long shot" but rather easy to try.
When I first got my O2 about a year ago, I was anxious to
quickly set it up and listen, to check it out. Upon power up,
it exhibited some odd glitches and noises, but otherwise worked
fine. After reading the caution in the manual about careful
grounding, I added a grounding strap between the power supply,
radio and the rest of the station. The "gremlins" quickly
disappeared..
