Okay - the problem is twofold:
*Lower Frequencies
*New Channel Plan
The lower frequencies being used requires the radio to have a new set of code put into the radio to allow the radio to go that low, as well as change some of the other operating parameters related to the receiver and transmitter.
There will be a new NPSPAC channel plan released, which must be flashed into the radio so that the radio changes to the correct new NPSPAC frequency.
If the radio can't be flashed, it can't perform these updates and therefore will be useless after rebanding. MTX-8000s are *not* FlashPort radios. It doesn't matter what you can do in lab, unless you can change the channel plan, you're SOL. Period.
I would also be willing to bet a lot of money that Motorola won't do a rebanding flash for anyone other than a PS agency......
Of course, this is all a moot point if your system does not require rebanding.
