Radio Censorship Conspiracy?

I have found it odd and frustrating that when I drive one of my vehicles to work, the two conservative leaning talk radio stations go to static when I hit a certain point. I have about a 30 mile drive to work and when I am within 10 miles of work these two stations simply cannot be listened to. The two stations are WLS 890AM and WIND560AM.

Now this is not in any of the other 5 vehicles I have ever driven to work over the years, so I know it does not affect every radio. I simply find it odd that it does affect this radio. I did note that I am close to the WGN booster for some of this 10 mile stretch, but it does not seem to have an effect on any other AM stations. WGN is fine of course. The two news stations 780 and 670 are fine. The Catholic station is fine. The Hispanic station is fine. The sports station is fine. Even the liberal talk radio station is fine.

It is so frustrating to be deprived of what I want to listen to the last 10 miles of my trip. What is even more frustrating is that when I return after work, the static stays longer than the point it begins on my morning trip. I have to drive 15 miles back before I can turn it on and sometimes 560 takes 20 miles before I can hear that.

I don't know if this is some kind of conspiracy that targets a small enough number of radio types to stay under the radar, but large enough to keep some people from listening. It is simply amazing that all the other stations work just fine, but the conservative stations have a problem.
