I have a 95 Dodge ram 1500, with a tyt-9800 Tri-Band radio. The power lead comes directly from the battery with a in-line fuse directly at the terminal. At the radio end, I have a noise filter that connects to the radio power, and ground. The antenna in mounted on the roof, with a 3/4" hole drilled, and routed through the headliner and down the backside of the truck away from any powered lines. I have no issues with the vehicle being off, but one I start the vehicle can hear wine in the radio, on mainly on the VHF range, but I get some noise on the UHF range. Would like some help to eliminate the noise, or where to start on tracing down were its coming from.
