Thanks Mike.Keep in mind that it's a 2 step process - you have to load new firmware to your BCT8 for Motorola rebanding -and- use software to put in the custom table to make it work.
We have the link for the firmware updates here...
Rebanding - The RadioReference Wiki
See section 7.1. Of course it would -help- if we knew what system you were trying to hear.... best regards..Mike
