So, my Z130BT's radio with the HD radio works fine EXCEPT for one AM channel, 810, and when it's on that channel, I get a high pitched whine, or whistle, that's in addition to the channel data, and it's very annoying. It gets worse under concrete underpasses or in a blocked area like a garage.
Has anyone else ever experienced this?
Note: this high pitched sound ONLY occurs on one radio channel, not on any other AM channel, not on any of the FM channels, and not anywhere else on the Pioneer head unit.
Any help or ideas would be greatly appreciated. Thanks!
