The licenses are for one channel block pair. I don't know if the FCC allows the use of frequency pairs spanning multiple blocks if the licensee has more than one block.
This is interesting as I think I've seen inputs to 152.xxx channels that don't always seem to be the mobile pair.
I could be wrong though with this being a trunked system that usually changes frequency with each repeater drop. If I don't notice the output has changed, I may be watching the wrong input.
I'll have to plug in all the inputs and do some studying of what I hear.
I know P25 systems make use of custom tables. I don't know if a custom table can be made for non standard inputs away from the listed mobile frequencies as they call them in the Wiki table.
Where did the "mobile" frequencies come from anyway? Is this just a carryover from the really old mobile phone days?
AFAIK, paging was just a one way service back in the day and did not need inputs.
I don't think 2-way paging existed back when this chart was probably made and then I don't really know if 2-way paging actually used frequency pairs. I really can't see how pagers transmitted a signal back anyway! Using a single AA battery must have been a challenge and greatly reduced battery life in a 2-way pager. Never owned one though so I'm just guessing how they worked here. I just can't see a pager getting a signal back to a paging system that may have sent the page out from a tower with an ERP of 1KW or more.
I'll stop here as I'm getting off topic but thanks for the info posted. It gives me something to do!
