Not excatly sure what it is, but if you give radio shack a call they should know. I took mine over there and told them what i wanted and they programmed it for me for free. Hope this helps.
Thank you both for the responses about the frequency book and radio shack, I do find it hard to believe nobody actually know the local frequency with all the scanner freaks in town. After an exhaustive search on the net, I think it is… 155.625, I’ll try that and see. Thanks all.
