I am programming my scanner to hear the Upper Maryland Eastern Shore Consortium. I have programmed the control channel and the alternates. The control channel is 868.98750. I was informed that to listen to certain channels (ie. Qfire-Tac 2) I can use the decimal 24688. I am assuming that I would program this channel as 868.24688. Am I correct or if I am not, how does it work? I am working with a Radio Shack Pro-197. Thank you for any and all help.
