upsman Posted August 26, 2012 Share Posted August 26, 2012 We got new Pinnacles at work and when you have the lights on there is a buzz in the am radio, very annoying. What is causing this and any cure? Quote Link to comment https://www.bigmacktrucks.com/topic/26999-radio-in-2013-pinnacle/ Share on other sites More sharing options...
convoyduel Posted August 26, 2012 Share Posted August 26, 2012 Having the lights on while listening to an AM station causes it. Our 2011's and 2012's have the exact same issue.

mike69mackman Posted August 31, 2012 Share Posted August 31, 2012 Unfortunate side effect of am radio picks up every electrical Impulse.

burnstransport Posted September 1, 2012 Share Posted September 1, 2012 Check the antenna connection on the back of the radio. The new shaker I drive daily picked up so much electrical interference on AM that you couldn't hear the programming half the time, I finally pulled out the radio, unplugged the antenna (which felt tight) plugged it back in and it was like night and day! It may have wiggled loose, preventing the antenna from getting a good ground which dissipates the stray noise interference. Easy fix and worth trying.
