Im sure at some point you will be told or will have an issue with a mot type 2 trunked system that has been re-banded..
I have a 93 and a 95 that are still running on re-banded sites with limitations...
Some scanners that could not be updated or flashed can still continue to track a re-banded system, but will not "hear" all the frequencies. The frequencies that cannot be received by legacy trunk-tracking scanners while in trunking mode are those frequencies that start with 851, 852, 853, and have a "0" (zero) in the fourth decimal place. If the re-banded system or site does not have any of these frequencies in the frequency pool, legacy scanners will be unaffected in their trunking ability.
In my case, the system I listen to has 22 freqs with 1 being a control channel. Out of those 22, 13 hold that "0" in the 4th decimal place. None of the 4 rotating control channels have a 0 in that 4th spot. So that leaves 8 voice channels that the scanner will use. Its not perfect, but it works for the most part.....
I use my 93 as a back up and the 95 to monitor my police trs as a back up while listening with my uniden.. It useful when trying to listen to more than one talk group...
