[edit] NATIONAL INCIDENT RADIO SUPPORT CACHE

This cache is maintained and used primarily for wildland fire, however, it may show up on any large incident such as floods, hurricanes, law enforcement (it was used for the Republican and Democratic National Conventions in 2004), and tornadoes. The cache is located and maintained by the National Interagency Incident Communications Division (NIICD) of the National Interagency Fire Center (NIFC) in Boise, Idaho. The use of these frequencies is coordinated by the NIICD Communications Duty Officer to avoid interference with nearby incidents.

NOTE: these frequencies can be used direct (simplex), but are most commonly used with repeaters. The repeater input frequencies are not shown. These repeaters fit in a small fiberglass case and are placed on the ground in a high place that provides coverage to all or most of the incident. Portable antennas and solar power are normally employed.
