CPS will get patched to PACS if needed, they also have 3 interop channels on CDR as well as HAWCS has a VHF for working with the RCMP outside of the city. Catching them working together is hit & miss, never a set time for crime
I cannot say for sure. District 6 and 8 are on the same dispatch. If a major event is occuring in a District, patrol units not involved will be changed to another channel, but not patched. I'm not sure what is happening in North Calgary as their call signs have changed. If a District is following a stolen car for example, they will ask Dispatch to let other Districts know. Even though a District car is out of their District [in most cases as there is a lot of complaints of radios going digital], they still have radio coverage through out Calgary. As masonb states, the only true patch I have heard is when RCMP require a patch to a District in the City or vice versa.
The Calgary City Police will patch with the RCMP ...
But as for districts ... they will Simulcast and join 2 talk groups into one.
they usually do that in the quiet hours when things are slow ... that way they only need 1 dispatcher instead of two.
