I'm 99% sure that the base frequency is correct as it jives with everything else I've seen/heard.
I'm thinking that I might be picking up an alternate tower with the same ID but on a different frequency -- possibly to increase its range.
OK, a quick reply, as I am supposed to be somewhere else.
The Base Frequency concept only works if the system uses contiguous Channels / Frequencies.
In Victoria, Australia, there is a Statewide system that basically goes from Channel 161 (164.0625) to Channel 251 (165.1875) in 12.5 kHz Steps,
You would expect 165.2000 to be Channel 252, but it is Channel 301, and the Channels go on from there up to Channel 364 (165.9875).
In TrunkView, you have to create a Custom Band Plan for this type of system,
Post some of the "wrong" Channel / Frequency pairs, and I might be able to come up with the required plan.
