If a radio looses reception completly it does a search over the whole frequency band. I had the same thing happening and to several sites in a system but I think it was just some error from the system managers as it was corrected after a few weeks.How real radios find this 'odd one out' control channel when needed is a mystery if a common base frequency is used.
Would that not cause confusion to the subscriber unit if it was operating in a RF dense area? All it would take is another TIII system using the same colour code and site numbers and it could end up on an entirely different network by mistake.If a radio looses reception completly it does a search over the whole frequency band.
With some help from a few people on a local facebook group, they have explained why this occurs and how it works.I have a CapMax network with many sites which all the CC and VC are calculated from the same base frequency with the exception of one CC.
If all possible CCs are programmed into radios with the frequency, then I would understand how radios find the neighbor CC.
I don't think this happens.

I know the odd CC belongs to the network because it shares the same neighbor list (common CCs).
I have no way of knowing when this would be used in a network and therefore cannot program calculator for it.

The base frequency is an unknown until a correct Ref. Frequency/Ref. LxN/RF spacing is entered.Perhaps support for these four different base frequencies could be added in the future? As you discover the up to four different bases you could enter them into the software. Then when you enter a new target, it displays the result in each of the four band plans as a new column on the table on the right. You could then test each result and identify the correct one.
