This flips me out. I have a late model American made auto. I used to get perfect AM and FM reception in the same areas I now (and for the past 8 or more months receive abysmal AM reception. This does not happen in another family vehicle (German). I kept wondering if it was a faulty AM module in my radio, interference (purposeful or otherwise in the area) or a bad connection with the AM antenna. The problem is intermittent. But sometimes (most of the time in the past six months) it's been really, really bad. So I got a NEW radio in my car. The problem still exists. Again, I never had a problem with my radio before.
"Again, I never had a problem with my radio before."
Makes ya wonder doesn't it. Who me?! cynical?!....nahhhhhh LOL
It began about 6-10 months ago, and even though I'm at the top of a 7300 foot hill, above the transmitter, reception there is terrible. So is cell phone reception, and that used to be perfect also.
The DOT put in an electronic scale that weighs trucks as they pass over a plate in the road. I'm guessing they messed with all frequencies as they did so.
