  • Radio Chirp

    My 2005 Thunderbird radio on AM has a chirp in it and it gets worse when I go under a bridge. Any suggestions

    If its a bridge like this I would suggest staying on top the bridge..... (sorry, couldn't resist)bridge.JPG

      It is a signal loss for certain, & you say it doesn't happen at all when tuned to FM? Only AM?

        Mine does the same thing on a weak signal. Try a stronger station.

          That's normal for AM, especially if it's a weak station. My wife's 2008 Buick and my 2017 Chev pickup do the same thing.

            AM signals are much more susceptible to noise than FM signals. General noise is found across all frequencies and will add/subtract from the amplitude of a given signal and affects the sound you are hearing on AM (amplitude modulation). FM (frequency modulation) signals are not affected by changes in the amplitude. You hear more noise when you have signals bouncing around structures (like buildings and bridges).

              A chirp is to be expected. You are in a bird.

                  The chirp is to warn you that the AM airwaves are full of propaganda.

                    Love the answers. I have three retro's and only does this on the 05. AM only and the station is very strong. Thanks for the support.
