Hey everyone, I've done some searches and cannot find anything regarding the problem I'm having.

The radio works completely fine, until I turn on AM 1120. This station sounds fine for about 10 minutes when I first turn it on, then out of nowhere an ear piercing sound continuously comes out. It sort of sounds like a tornado warning, and amplifies whenever you have something overhead, I.E bridge/light pole. I have recorded a video(try to listen past the hockey game broadcast). As soon as I turn the volume to 0, the sound goes away. When its volume 1 or above, you can hear the sound and it gets louder as the volume gets louder. I switch AM stations to show that it doesn't do it for anything else besides this certain station (This station works fine in every other vehicle I own or have owned.)


Hopefully someone has ran into this problem, or knows the cause of it.

Thanks,
Cameron

Since AM radio runs through the chassis of your car rather than the antenna it's pretty common to get a whining in your radio since almost everything in your car grounds to the chassis as well. A lot of times, on AM radio, you'll hear the whining increase or decrease in pitch in direct correlation to your RPMs (the higher the RPMs the higher the pitch).

The only thing I can recommend is to check the ground connection to your radio or maybe relocate the ground wire to a different spot.

As far as it only happening on one channel, that's all that comes to mind is the frequency of the channel conflicting with the other electronics that are grounded to your chassis. This would also explain the fact that the channel works fine in other vehicles because each vehicle has different electronic components grounded to the chassis.

AM radio issues can be a pain! Good luck.
