I hope that CORN, doctree2, and motoapco25 can provide that information and how to re-program these into the scanners, RS, GRE, and Uniden.
To start off, Metro has already completed the reband process. The RR database has the rebanded freqs listed as well as several new talk groups available.
As for programming, my radio is a Gre PSR-500/600 and i had to set a custom table for system B but wasn't required to do anything to system A (just plug in the control channels and your good to go).
System B: Put in the control channels then set your custom table. There are 6 sets of parameters for the Gre radios to trunk properly. The RS scanners also require a custom table identical to the one below.
Custom table:
1st set of parameters: Lo Ch: 440
Hi Ch: 559
Offset: 440
Base: 851.025
Step: 25
2nd set of parameters: Lo Ch: 0
Hi Ch: 719
Offset: 0
Base: 851.0125
Step: 25
3rd set of parameters: Lo Ch: 720
Hi Ch: 759
Offset: 0
Base: 848.0
Step: 25
4th set of parameters: Lo Ch: 815
Hi Ch: 831
Offset: 0
Base: 846.625
Step: 25
5th set of parameters: Lo Ch: 958
Hi Ch: 958
Offset: 958
Base: 868.975
Step: 25
6th set of parameters: Lo Ch: 961
Hi Ch: 1022
Offset: 0
Base: 843.4
Step: 25
The end. And like i said, thankgoodness, you don't have to do anything special for System A (the main pub safety system). Programming can also be done via the computer but if you want to do it that way don't ask me cause i'm old school and program things by hand. Good luck and may the force be with you.
