Radio Interference At Idle

[Fr8Dog]

I apologize if this topic has been addressed somewhere else--I searched the forums and couldn't find it.....

The problem in my 2013 2500 6.7l is whenever I come to a halt, engine running (like at a stop light), there is a steady "electronic whine" that comes over the AM radio. Obviously, doesn't occur on Satellite or FM. It doesn't ever vary pitch like it's following rpm. Once I get moving again--about 10 MPH, it disappears/stops.

Anyone with similar problem? Suggestions? Thanks.

Must not be alternator induced since it does not vary in pitch. Have you added any aftermarket electrical accessories?

 

[Fr8Dog]

Nope, totally stock.

Although this is focused on new installs, it may give you some ideas and fruit for thought:

In my quick search on this issue, the common thread of the returns keep saying check grounds and antenna.

Best of luck on finding the Gremlin.

"comes over the AM radio" AM has always had a lot more issues with noise interference! SNOKING

I've not listened to AM since I had 8-track tapes---and a mullet.

Whats an 8 track tape? LOL

Back in those days, you'd simply go to Radio Shack and buy an in-line noise suppressor for the power feed wire.
