Is it pretty quiet? I have a sound effect that might be described as static that I only notice when radio is low. Sounds like it’s coming from somewhere near the main screen. It sounds sort of like the sound effects our old IBM PC would make when making heavy calculations. I’ve assumed it was some sort of electronic related noise. It doesn’t seem to be coming from the where I believe the AP computer board to be (near glove compartment, you can sometimes hear a little fan there).
