The 99 watts from 4 Times Square may be going over everyone's heads at ground level, and may actually be stronger in the upper floors of the skyscrapers of Manhattan. Or maybe it's not running full power yet. 106.3 is a really bad frequency with Thunder, WFAF, and all the pirates. It's going to be tough to get people to listen to it in their cars. I think 87.7 would be a more valuable frequency than 106.3 even with half the car radios unable to tune to 87.7.
As someone mentioned before, there's a 106.3 pirate in the Bronx that covered most of Manhattan till the 40s (it could be heard on the ground at 4 Times Square). That pirate must be fighting with the translator in uptown. Clear Channel might regret paying so much for the translator when they realize pirate stations have better coverage. The best low power signal in New York is the 94.5 pirate in the Bronx which blankets Manhattan, Brooklyn, and Queens and even spills over into Jersey.
