If i set up a digital business radio VHF / UHF network, and I set up a mesh of repeaters across a city...?

Question: Would each repeater away with and transmit on exactly the same channel, or would each repeater have its own 12.5Mhz convey, therefore requiring some sort of roaming setup to be programmed into the radio units?

I am very new to this technology and worrying to self


Answer: You'll have to set up the repeaters so they don't encumber with each other. If they're close together they will need to be on separate frequencies. If they're far enough apart they can use the same frequency. Far enough aside from can be up to 100 miles depending on terrain

County scores key FEMA grant for emergency radio equipment

The taxpayers of Carlton County received something of a stroke of good fortune this week.

At Monday’s adjourned session of the Carlton County Management, Sheriff Kelly Lake informed commissioners that the county has been awarded a Federal Danger Management Agency (FEMA) “Assistance to Firefighters” offer in the amount of $684,585. The grant will help fund the purchase of radio equipment required for the mandated upgrade to the ceremonial’s new Allied Radio Matrix for Emergency Response (ARMER) narrow-line operating system.

The move comes, in part, in the face of a rapidly increasing demand for radio frequencies due to the universality of cell phones and other personal communications devices. The narrower body width will accommodate more information while at the same time take up less radio spectrum.

ARMER is a digital trunked system operating at 800 MHz that would produce 99 percent coverage of the county via stationary and mobile communication devices and allocate users to communicate seamlessly with each other as well as agencies throughout the state and country.
