DNRC radio communications personnel work directly for the Fire and Aviation Management Bureau in Missoula however, we repair and maintain a statewide radio system used by the Field Operations Division for the detection and suppression of wildland fires.


Lookout Tower

The radio system consists of 29 mountain top repeaters and 20 office base station sites, from Libby to Dillon east to Billings and Ekalaka north to Zortman and west to Lewistown, Helena, Missoula and Kalispell.

Included in this radio system are more than 1000 handheld, mobile and base station radios which are used by wildland firefighters, foresters and administrative personnel.

All FCC licensing for the Field Operations Division is performed and maintained in Missoula along with the repair and maintenance of the radio equipment. New equipment is ordered and processed here as well.

Tactical Radio Cache
Portable Solar Repeater
During the fire season "commo" personnel establish radio communications for wildland fire incidents using a variety of specialized equipment. This includes tactical radio caches, portable solar and battery powered fireline repeaters, temporary base stations, aircraft radios, satellite telephones and a mobile command trailer.

This 24 foot trailer has been modified by DNRC to serve as both a communications center and command post. Power can be supplied by an outside AC line or from the onboard generator. The communications equipment can also operate on DC power supplied by the self-contained battery.
