nec911, is template talk groups set up in a grid? JOCO and City Fire/EMS have talk groups set up in a grid. They dispatch calls on ECC Dispatch and also on 302xx through 30299. I've been looking online for a map of the grid and haven't found it yet. It seems Miami County, KS has been on 31190 FIRE/EMS OSAWATAMIE. Since, they are not signed up for MARRS (that I know of) I guess they have a talk group because half of Spring Hill is in Miami CO. Or they are contracted for calls in the Southern part of Spring Hill according to their Fire District map.
