I have a RS Pro-164 handheld scanner. When the truck is running im getting what kind of sounds like alternator whine coming through. You can rev the engine up and hear the interference sound like it. I dont have to have the power plugged in (is running on batteries) so I know its not coming in through the power wires so it has to be coming in through the antenna. I have tried another antenna and also another scanner and the same thing.
I am assuming its coming from the coil, wires, or cap or possibly the alternator via frequency. The ignition system is the HEI ignition. When i put the scanner on the CB band it does not do it at all. Clear as a bell.
Around 460 mhz, on FM mode with the squelch all the way down, when someone keys up the interference comes in but not if no one is talking. If I put it on AM on the same channel, the interference comes in whether someone is talking or not with the squelch all the way down.
Maybe someone has had this issue before and knows where the problem is or how to troubleshoot and isolate the problem. It is so bad that you can barely stand to listen to the scanner because it is so annoying and drowns out what is being said.
