Here are a few from my neighborhood.
WVGR 104.1 Grand Rapids- 20 miles from downtown Grand Rapids
WOOD 105.7 Grand Rapids- 20 miles
WBCT 93.7 Grand Rapids- 23 miles
Of course, these stations are all grandfathered. So they probably all make it into Grand Rapids as well as some of the Class A in-town signals.

Distance isn't the issue, it's how much RF a station put's into a location that determines what the city of license is. I forget the law but I believe if station a who's transmitter is 50 miles from city B but covers that city with either a 5 Mv signal on AM or a 2.5 mv on FM and who's main studio is located near the city of license (WPHT has a studio in Bala Cynwood but is licensed to Philadelphia)can claim a specific city as the city of license.

First, Bob Marvin is correct... the FCC requires a minimum signal over the city of license.
But the City of License is not always the city served. KQMR in Globe, AZ is 80 miles from the center of the city it serves, Phoenix, and about 85 from its studio. That is a class C fM. One class A I know, KRCV, has studios over 40 miles from its transmitter (Glendale to san Dimas, CA.
Now deleted, the 540 AM in Costa Mesa Ca had transmitters in Hesperia, over 60 miles from the city of license. For a while, KAIM 870 in Honolulu doid not even have its transmitter on Oahu, but, rather, across the water on the island of Hawaii, about 45 miles distant.

Thats the first time Ive heard that. As far as I know..the only requirement is..at least for AM...there must be at least 25 mv/m of RF in the middle of downtown of the city of license.

That's basically what I said. It's the amount of RF and not the location. I asked a friend who used to work for WBZ and he's the one who gave me the numbers. Memory on exact figures might have failed becaue I thought at one time it was 50 MV on AM.
