I disconnected the scanner from the computer and shut the computer down to see if the interference was coming from the pc, but still no luck. I have the scanner turned down pretty low, so I know it doesnt have anything to do with the scanner volume. Im assume its outside interference. Ground/Tower controllers come in clear, aswell as south App(119.9), but theres tons of static on 126.6. They make filters for these kind of things right?
