I have an SDS 100 and am trying to use Sentinel software to program the MRC Tier 3 system as a favourite from Waterloo Region. It shows up in the Waterloo trunked systems list in the RR database, but even with the database updated in Sentinel, I cannot find this system.
If it's under Waterloo Region Countywide systems, I am clearly blind. I thought the Sentinel/SDS100 database was data exctracted from the RadioReference Database. Where can I find the the MRC System in Sentinel's database?
