I hope Clear Channel doesn't lose any advertising revenue with this move. Me and a friend drove down to Trenton, NJ on Saturday to see an afternoon game with the Trenton Thunder (AA-level New York Yankees). He tuned his car's radio to 97.9, near the tunnel on CT Route 15 at the Hamden/New Haven town line. He was already getting a decent signal of 97.9 FM from New York City. There was no trace of WUCS-FM at that time.
As for the audio of the game, it's still in mono, just that the audio fidelity is a bit better, since they're on FM.
Meanwhile, the New Britain Rock Cats are on WPOP-AM 1410 of Hartford. Too bad that only a handful of those games are airing on the station. I'm fairly certain that WMRD-AM 1150 of Middletown isn't airing any of the games anymore.
On a side note, I was at the chilly season opener on Thursday evening at New Britain Stadium. Gone were any of the advertisements related to CBS Radio. Besides the ad on the outfield wall for WPOP-AM, there were ads near the concessions for WKSS-FM 95.7 and WHCN-FM 105.9. Both had the prominent I-Heart Radio logo either on the top or side of the ad.
