Not that it helps you with the issue of not hearing anything, but just a heads up. The database entry for Niagara EMS can be a bit confusing. There are channels listed as "Hamilton Niagara North" and "Hamilton Niagara South". These are NOT used in Niagara anymore. Niagara got back it's own CACC after the Fleetnet radios were configured. You'll want to be sure you program the ones under Niagara ACS (Niagara North, Niagara South, etc...)
