how old is your car? sounds like electrical noise that's more pronounced when the engine is cold i.e. mornings

What you are experiencing is "skywave" propagation. The CRTC and FCC ( U.S. ) requires radio stations to reset their power at dusk and at dawn. Sometimes you will catch radio stations excusing themselves for about 10 to 15 seconds to reset power. The reason for this is that AM radio waves travel much more efficiently at night because the layers of the ionosphere above the earth changes drastically from daytime to nighttime. Radio stations are licensed by the CRTC to broadcast at a certain wattage and to cover a general radius area. To maintain that general area of coverage they will increase and reduce their broadcasting wattage. If they did not reduce their power at dusk and power up at dawn they would possibly cover hundreds of miles more and overlap other radio stations far away.
You have noticed this recently because your commute time has coincided with sunrise, as the days go by you will notice this interference later in the day and disappear when the radio station resets power at dawn. You notice the interference on some stations and not others because you are on the fringes of some stations and close by to others.
Why not be a smart lil' cookie and take the fucking car to a AUDIO store and ask them instead of insisting to a bunch of dudes on a hooker forum to know the exact reason your specific car is having issue without even looking at it, knowing the make/model/year etc? And if they don't have the answer you want, you bitch at them like a woman on PMS.
LIKE WTF????
LIKE WTF????
Tell us how you know this is "… only in my vehile[sic]", and only during sunrise. How many other cars have you checked during sunrise and how often at other hours have you positioned your vehicle just as it was during sunrise? It's verges on impolite to chide someone trying add some appropriate sort of technical precision to your imprecise description in your request for help. And without you supplying an embarrassing amount of personal detail—what car, what location, what hours, what direction and speed,—all answers will have to be general.
AM signals aren't just subject to atmospheric noise, they're also notorious for bounce due to electro-magnetic conditions in the atmsphere, which vary as the the weather and the amount of sunlight. As a kid I could tune in Radio Moscow's AM signal in Ottawa, but only after midnight, and every teen in my circle knew where to find WWVA from Wheeeling, West Virginia on the car radio, if only to avoid the voice of the Grand Ol' Opry when snuggling in to watch the submarine races. It could be coming from anywhere. Apart from getting a better radio (and car radios have long had the best AM tuners available) all you're gonna be able to do is tune to something else.
I was trying to warn her about the pending alien invasion, and this is the thanks I get from her?!!

Maybe she doesn't like cats???? Personally I love me some pussy. But hey, to each their own, right?
You guys should get satellite radio anyways. Ever since I got Sirius I've been in 7th heaven and I never looked back

Oh do please enlighten us with this vast knowledge so that others will not have to go down the same road as you of not knowing why they have AM radio issues in the AM.
Wait now.... How silly of me and convenient for you. PM's are not allowed to be shared in public.
Never mind then. As you say, case closed .
WOW. Didn't know that option was available. Bought my car in November and ended up with a regular one.
