BC296D and FCC Channel Number Assignments

[wr7agt]

Hello all. I have a 296D coming monday for use on our new Montana APCO 25 system being turned on Feb 1. In looking at an on-line manual on the thing, there is a comment that auto programming wont work on VHF trunked systems. They ask for something called Base, Space, and offset frequency info for the system. I have the complete list of all the VHF channels going to be used in the system, not that many.

The Control Channels at each of the 5 sites are up and running now.

As best I can figure out, they want me to program in the lowest frequency used by the system base stations. They want the "space", which I believe to be 15Khz as the channels are all standard frequencies in the VHF Public Safety pool. But I read that offset is to be the actual "Channel Number" of the lowest freq, or the freq I use as the Base. Now, I am very familiar with 800 and 900 MHZ FCC channel number designators for each frequency, but, I have not been able to find such a designation list for VHF channels. Part 2 and 90 was searched, but couldn't find anything.

So, does anybody know where this info can be found? Or, am I all wrong in what the scanner is going to need to work on a VHF system?
154.340 is the lowest frequency of the base station assignments.

Thanks,

Tom

channel assigment

The Channel number they want is as follows
every trunk system consist of 380 Channels for Recieve and 380 Channel for Transmit
so he need to know what is the channel number for the Receive ...
read the following and you will Understand about it ....

The 380 channel receive and transmit limit is not applicable to APCO-25 systems. APCO-25 systems have a total of 65536 possible channel assignments which are RX/TX pairs. This leads to rather complicated VHF/UHF tables. See Alaska's ALMR for an example.
