How will my scanner work after rebanding?
Today if a non-rebanded scanner is told to go to channel 448 in a rebanded Motorola system, it calculates the frequency as (862.0125 + (8 x 25 kHz)) and jumps to 862.2125 MHz. The problem is that channel numbers 440-559 have been “borrowed” to cover the new channels at 851-854 MHz. The correct frequency for channel 448 in a public safety system is 851.2250 MHz, but the scanner doesn’t know this. Even if all of the new frequencies for the system are programmed in, the scanner still relies on the above calculation during trunking and will always tune to the wrong frequency. If a public safety site or system uses ONLY the general category or 1-120 channels described above and/or channels between 854-862 MHz, a non-rebanded scanner should still track that system correctly, because it knows how to find those channels. However, most Public Safety systems are using a mix of existing (1-120) and “new” channels (440-559), and they will miss any communications which are assigned to the new chann
