System Notes

This is the new University of Michigan, Project 25 TRS. This new simulcast system has replaced the older Type-II legacy that had been in use form many years.

Channel Bandplan seems to indicates this system will be a "Dynamically Mode Switching" P25 system.  Meaning it will be able to switch between Phase 1 and 2 operation based on radio affiliation on specific talkgroups.  Also, there may also be some 900 MHz integration as well.  Channel table listed below:

Bandplan 0: Base=851.00625 Offset=-45 Spacing=6.25 BW=12.5
Bandplan 1: Base=762.00625 Offset=+30 Spacing=6.25 BW=12.5
Bandplan 2: Base=851.01250 Offset=-45 Spacing=12.5 BW 12.5 Slots=2
Bandplan 3: Base=762.00625 Offset=+30 Spacing=12.5 BW=12.5 Slots=2
Bandplan 4: Base=935.01250 Offset=-39 Spacing=12.5 BW=12.5
Bandplan 5: Base=935.01250 Offset=-39 Spacing=12.5 BW=12.5 Slots=2
