I just don't get why anyone with half a brain would file a co-channel inside the 60dBu of a class B!! 102.7 and 101.9 are both class B's in NYC, with 6kW ERP from the top of the Empire State Building.
You've put your finger on it. A lot of these were, indeed, filed by people with half a brain. But I guess they were hoping for some kind of a miracle at the FCC.
And let's face it, every so often, usually with the help of a senator, somebody with half a brain gets a free pony from the FCC.
