Nothing says "ACTION PACKED!" like the Commisionaires!
Quite a few, also depends on the location. Some sites are also encrypted so well, it makes the new RCMP system in Ontario look like a FRS radio..
It would help if you tell us what your wanting to listen to (actual site/location)
Thanks for your assistance!
I use a Radio Shack PRO 92 and I'm familiar with trunked systems.
