I've come across a new fire buff network at www.tspsr.org, the Tri State Public Safety Radio Association. Says they operate in the Bucks Co (PA) and Mercer/Hunterdon Co area with expanding coverage coming. Has anybody heard of them and know what freqs they're on? FYI, East Coast 911 repeater 451.900 is no longer operational, and haven't heard Philly Metro Radio, 464.25 in quite a while.
