I have an ORION UHF100 receiving interference from a HD DVR Dash Cam on Channels 9 & 10. All other channels work fine.

I also have a PIONEER FM MP3 player receiving interference from the dash cam as well on FM.

The UHF is directly connected to the car battery + Terminal, and grounded to the chassis. The Coax for the UHF runs inside the car door frame on the right, and the FM aerial is factory installed on the left.

When the DVR powers on and records, the interference is evident - and is the same issue whether the DVR is running on its own battery or plugged into the car's 12V cigarette lighter.

It's obviously radiation from the DVR, so I need advice in how to block the signals even partially to stop this nuisance.
