I run a website webpages.charter.net/radiosite/MidmichiganScanner.html
and would like to add to the Saginaw list I have as well as you can add to the database located on this site.
I will have to listen closer. My son is a summer worker and said they just got new radios, Seems like the numbers are 12223-12231 or something like that. Each garage has there own radios.
Heck what ya could do is well, "visit him" at work and have him just if he can just key the mic on each channel, no voice and you could record what it is on the radio and id on yours.
I've done it before when it could be done
