From the press release (via David Lennon):
WFAN will produce exclusive Mets programming with players and coaches, daily highlights packages, and pre-game and post-game reports both on-air on WFAN-AM 660 and on the station’s online audio stream at www.wfan.com. For the first time, all of the station’s Mets content, including game broadcasts, will be available on FM radio at 92.3 HD3.The agreement keeps the Mets on WFAN (and HD3) for 2009 "and beyond."
Well how about that! First of all, I'm excited for Feb. 2009 because baseball will be starting again, but now I can listen on 92.3 for non-whining and screeching broadcast of the team. Thank goodness.
Update from commenter Adam:
You can only listen on 92.3 if you have a HD radio- that's what the HD3 means - they'll be on an HD substation. You won't get any Mets on your "regular" FM radio
Well, shucks. There goes that.
