Still not sure what you are trying to do by sticking two trunk systems in the same bank.
Waterloo Region is an edacs system and Peel is a Motorola Type II. You will be able to select trunking for all 800Mhz frequencies now but you will only be able to listen to one system at a time.
If you get within range of Waterloo, you will need to change the system type over to 800Mhz edacs and make sure you have the frequencies in the right lcn order.
