National Incident Radio Support Cache
The NIFC Radio Cache is the largest in the world consisting of 8,000 handheld radios, 200 repeaters, and 15 portable satellite systems, containing about 10,000 pieces of equipment worth $26 million. This equipment can support about 32,000 firefighters or 53 major disasters at one time. This cache is maintained and used primarily for wildland fire, however, it may show up on any federally supported large incident or disaster such as floods, hurricanes, tornadoes, law enforcement and large special events (it was used in 2004 for both the Republican and Democratic National Conventions). It is located and maintained by the National Interagency Incident Communications Division (NIICD) of the National Interagency Fire Center (NIFC) in Boise, Idaho. The NIICD Communications Duty Officer (CDO) is the nationwide incident frequency coordinator for this cache and issues authorizations based on potential interference with nearby incidents and other agencies. The CDO coordinates aviation (VHF AM) frequency use with the FAA, the sole agency responsible for the use of aviation frequencies.
Each Geographic Area Coordination Center (GACC) can order 4 basic "Starter Systems" for preposition during their established fire season. A Starter System consists of 10 boxes of assorted equipment including 1 VHF Repeater/Link and 1 UHF Repeater. Generally the frequency assignments for these repeaters will be one of the standard VHF Command assignments (C1 through C6) and one of the standard UHF assignments (L1 through L7). Any UHF frequency listed on the "Logistics" table below can be used to link command repeaters and VHF AM "Victor" remote bases to the Incident Command Post and other locations such as a heliports, portable retardant plants, etc. Repeaters are installed in fiberglass cases for shipping and placement. Antennas, batteries and installation/maintenance tools are included as communications unit staff may arrive via aircraft with weight restrictions that prevent carrying tools. All command repeaters are shipped with UHF link radios installed.
If an incident grows in size and complexity communication needs will change. Incidents have different characteristics such as the type of incident (fire, earthquake, hurricane, special event, etc.) topography, size, number and types of resources assigned, type of incident management team(s) assigned, fuel type(s) burning, existence and proximity of wildland urban interface areas, distance from towns, distance from air tanker bases, the number and type of aircraft used, location of shipment receiving facilities, number of VHF handheld radios brought by arriving resources, cell phone coverage, availability and type of Internet connection, and availability of commercial electricity. Mobile radios installed (25 watts and up) in fire apparatus are not cloned and systems are designed to provide handheld radio (normally 5 watt maximum) coverage. Communication systems need to be designed that take these factors into consideration. Communication system components are available in 25 prepackaged kits. These kits are then used to build a system that meets all the incident's needs.
If one command repeater cannot provide coverage of an entire incident an additional command repeater(s) is placed in locations that collectively provide full coverage of the incident. These repeaters are linked together with UHF repeaters in an integrated system that allows each repeater to carry the traffic of all the other command repeaters. Each handheld radio is programmed with the frequencies of all the command repeaters used on the incident. This enables each handheld access to this integrated system from all locations. If remote bases are installed that a scanner cannot receive, topography and location may allow reception of link frequencies. Entering each of the frequencies on the "Logistics" table below in a scanner is a good start when searching for UHF linking frequencies.
The frequencies shown in the tables below are permanently assigned. For reasons that are not always clear, perhaps due to interference or leaving frequencies available for potential new incidents, temporary frequency authorizations may be issued on an incident by incident basis. Frequencies are selected by the communications unit leader of each incident using a database list of frequencies assigned to all federal agencies in the area of the incident. The communications unit leader selects currently unused frequencies and requests CDO authorization for their use. The CDO considers the needs of other incidents and may authorize the requested frequencies or authorize others. These authorizations cover the limited area of incidents and only for its duration. Subsequent incidents in the same area in the same year may have different frequencies assigned to it. It is not entirely clear if authorizations are carried over to the next year. Conversations with communications unit leaders at incident scenes indicate they are not. Several Radio Reference members have reported the use of some command frequency pairs for more than one year, with the name of the frequency (Command 37, etc.) staying the same.
- Frequencies listed here are subject to change at any time and are not verified to be 100% accurate, complete or current in all areas.
- All frequencies listed are narrowband FM (FMN). It is possible that P25 digital mode may be used in some areas. According to Interagency Aviation Tech Bulletin dated February, 2008 all aviation FM radios are required to be P25 capable.
- A partial list of pre-assigned national frequencies is contained in Chapter 15 - Communications of the publicly available document Interagency Standards for Fire and Fire Aviation Operations (Redbook).
- Starting in 2014 per the National Incident Radio Support Cache User’s Guide "New for 2014" on page 2, incidents are advised to program CTCSS tones in all VHF repeaters (command) and all tactical frequencies. The communications duty officer (CDO) assigns the tones on an incident by incident basis.
- Handheld radios are cloned per the Incident Radio Communications Plan (ICS 205). Mobile radios are not cloned.
Tactical
These frequencies are authorized for use in handhelds and mobiles only. Installation in base stations is not authorized.

- The authorization for Tac 4 was terminated several years ago. A replacement frequency has not been authorized.
- Some U.S. Forest Service regions and BLM state offices now have unique tactical frequencies assigned for day to day work, initial attack and locally managed (Type III, IV & V) extended attack incidents. The objective is to use the NIFC tactical frequencies on nationally managed (Type I & II) extended attack incidents only. It is unknown if other Forest Service regions and BLM state offices will be assigned unique frequencies to meet this objective nationwide.

- (1) The authorization for Command 7 was withdrawn in 2011. Authorization has not been issued for a replacement pair of frequencies.
- (2) Command Channels 8-12 are in the Federal Interoperability Channel Plan as NC1 and IR1-IR4. See the NTIA Federal Incident Response Channel Plan for more information. These channels are listed in the 2015 California FIRESCOPE communications plan. There is a single verified report of one of these frequency pairs being used on an incident outside of California. This would indicate these commands are available for use outside of California.
- (3) Members have reported these command frequencies being used on large incidents. Some have been listed on copies of incident communication plans obtained by members. Those shown with no frequencies have been shown on publicly available incident maps, but without access to frequency information or reception reports. The commands highlighted by notation (3) may not be permanent, long term, wide area authorizations, rather are temporary use of frequencies in the pool of unused federal frequencies that are assigned on an incident by incident basis. The use of these frequencies, most especially the names, i.e. "Command 16," may not carry over to subsequent years or to incidents outside the area they were authorized for. If nothing is heard on Commands 1-12, these additional command frequencies may be in use. Members are requested to report if they are and if the same name is applied to them. Use of command channels in the gaps between those listed has not been reported.
- The use of CTCSS tones on both the transmit and receive frequencies is necessary due to interference with other incidents that might be within "earshot" of other incidents, other RF sources and, in the case of incidents in proximity to Mexico, illegal use of these frequencies. The latter is common in the southern portions of the region covered by the Southern California and Southwest Geographical Area Coordination Centers.
Logistics
This information was confirmed from official information as of 2009 with updates from 2015.
The outputs can be used simplex as well.
Links for aircraft are typically dedicated to aircraft operations.
These frequencies may also be used for cross band repeaters and links.
The repeater input/output frequencies of Logistics 1 -7 are sometimes reversed for different repeater configurations and some of the inputs may be used for simplex.

- Aircraft links provide communications for the Incident Command Post (ICP) and/or Heliports - Helispots to/from distant VHF AM ("Victor") frequency remote bases. The aircraft transmit on Victor frequencies and the ICP and heliports/helispots receive it on UHF frequencies, which in turn, via the link and the remote base, transmit back to the aircraft on VHF AM. This situation exists when the size of the incident is large and/or the topography is mountainous sufficient to prevent VHF AM air to ground communications over the entire incident. VHF AM radios transmit at very low power, but due to elevation cover a significant area. Low power is used to reduce the chances of interfering with nearby incidents.
- In some situations repeaters used for logistics purposes only are placed in high locations when the ICP and supply sources or receiving/distribution centers are in separate and distant locations.
Air VHF FM ("Foxtrot Mike") Frequencies
These include National Air Guard, National Flight Following and the 73 channel National Air to Ground system. Air to ground frequencies are assigned for initial attack to zones within each state. If the incident grows larger (extended attack) a new air to ground frequency(s) will be assigned. This assignment obtains frequencies from two sources: unused National Air to Ground system frequency(s) or unused federal government frequency(s) in the area of the incident. These assignments are made after approval by the Communications Duty Officer of the National Interagency Incident Communications Division (NIICD) at the National Interagency Fire Center in Boise, Idaho. The frequencies might not be used on other incidents or even used in the same area in the same, or subsequent, years.
Prior to 2013 there were 5 national air to air FM tactical frequencies that were used for both initial and extended attack. These 5 frequencies are now part of the National Air to Ground system and, with the exception of California, air to air tactical traffic is conducted on VHF AM aviation frequencies. California has 31 federal air to air tactics FM frequencies with 2 or 3 assigned to each of the 18 national forests in the state.
When an incident evolves into an extended attack, the air tactics group supervisor (ATGS) makes the request for extended attack air-to-air tactics and air-to-ground frequencies be assigned. When frequencies are approved it might occur while the shift is in progress. When this happens the change is announced on all the aviation frequencies in use and the command frequency, which during the initial attack phase is most often the forest net (USFS), district net (BLM), park net (NPS), refuge net (USFWS) or the fire/emergency net of any of those jurisdictions. This is gradually changing as maintaining confidentiality of frequency use is increasing.
In most circumstances the unique extended attack air-to-ground frequency change will be made effective the beginning of a shift. In this case all frequency changes are announced at shift briefings and listed in the shift Incident Action Plan. Shifts are 0600 to 1800 (day shift) and 1800 to 0600 (night shift). Almost all changes are effective at the beginning of day shift, as that is when most aviation activity occurs.
If this announcement is missed anyone monitoring a large incident that uses air support should search the federal VHF frequency band (162.000 MHz - 174.000 MHz, 12.5 kHz steps) to find the VHF FM air-to-ground frequencies if traffic is not received on the pre-assigned frequencies listed below.
National Flight Following is used by the almost all interagency dispatch centers, however, some of these now have their own local flight following frequency assigned for use in their areas only. These local flight following frequencies are employed when aircraft are working within a dispatch area. These frequencies will be listed in the state by state federal government listings as soon as they have been confirmed by listeners.
According to this document there will be two, and three in some cases, permanently assigned air-to-ground FM frequencies for each initial attack zone nationwide. This information has been taken from confirmed sources and is accurate as of January, 2014 for all but the Alaska GACC and Southern GACC. The Southern GACC information is valid as of 2/2013. Alaska uses VHF-AM (Victor) frequencies for air to air and air to ground communications.
These frequencies are not assigned for air to ground exclusively nationwide. Some of the frequencies may be used as National Forest, National Park, BLM District or National Wildlife Refuge primary nets or local tactical channels. Air to ground frequencies are assigned in a manner that interference with local nets is not possible due to distance and/or topography.

Air VHF AM ("Victor") FrequenciesThe FAA has jurisdiction over the VHF AM aviation band. Authorizations are issued each year by April 1st and expire on November 1st. All frequencies are subject to change each year. All dispatch zones have 1-3 air-to-air frequencies assigned for initial attack, depending on the wildland fire workload of those zones. Temporary, incident specific frequencies, are assigned to extended attack incidents, by NIFC following authorization by the FAA. The table below shows permanent and nationally assigned frequencies.

National Airtanker Base Information and Radio FrequenciesThis information was confirmed from several credible sources as of 2014. These are VHF-AM "Victor" frequencies. These frequencies are assigned and authorized by the FAA, not NIFC. They are subject to annual revision by the FAA. Most bases use 123.975. All bases are listed, in spite of the apparent redundancy, to show where current air tanker and retardant reload bases are located. The listed bases may have season long or partial season air tankers, or may only be used for reloading retardant for an active incident nearby. Most air tankers do not stay in one place for an entire season. They might start in the southwestern U.S. in late April or May, When monsoonal rains arrive in early July they are moved to areas where the burning conditions have become critical. Contracts schedules are determined in late winter and early spring, with a set schedule that moves the aircraft to match the average or typical peak fire season of each geographical area. This schedule is subject to change if the fire season varies from the projection. State owned air tankers in California are not national resources and with very few exceptions don't leave the state. Most stay at the same base, but are temporarily pre-positioned in other areas as conditions dictate. SEAT stands for "Single Engine Air Tankers." They are similar in appearance to crop dusters as they are modified agricultural aircraft. Retardant capacity ranges from 400-800 gallons. MAFFS stands for Modular Airborne Fire Fighting System. There are (8) C-130 (Hercules) military aircraft that are owned by the U.S. Forest Service and maintained and flown with military personnel. They can be mobilized or pre-positioned at a limited number of civilian airtanker bases when all civilian air tankers (under contract) have been committed or are expected to be committed. They are housed at one Air Force base and three National Guard bases. Those bases are: the 146th Airlift Wing, California National Guard, Port Hueneme; the 302nd Airlift Wing, Air Force Reserve, Peterson Air Force Base, Colorado; the 145th Airlift Wing, North Carolina Air National Guard, Charlotte; and the 153rd Airlift Wing, Wyoming Air National Guard, Cheyenne.
Federal Government CommonThese are used for local tacticals in some areas, however they are common for the entire Federal government. These frequencies are often used as tacticals, or commons, in National Parks. See Federal Government Itinerant. As of January, 2008 the NTIA Redbook contained direction that 168.350 and 163.100 are to be used as a repeater pair, with 168.350 being the input and 163.100 being the output. This repeater pair is to be used for temporary, or itinerant, repeater placement. Simplex use is permitted if the four new federal common frequencies are already in use. Some agencies are now using the new commons in place of this repeater pair's frequencies. In spite of the direction there is widespread use of these two frequencies for simplex, tactical and travel purposes.
Intra-Crew Communications
Handheld use only. Crews are encouraged to use Continuous Tone Coded Subaudible Squelch (CTCSS), or Network Access Code (NAC) while in digital operation, to reduce interference from other crews or other federal uses. This is not an exclusive assignment as these are VHF federal common frequencies and may be used by any agency at any time or location. These crew nets are to be used for crew logistics only and tactical communications are not allowed.
Family Radio Service (FRS) communications equipment shall not be used by anyone associated with federal wildland fire incidents or in instances that safeguard human life or property. This applies to agency, military, and contractor personnel. NTIA Manual, section 7.5.8, states: “federal entities may not purchase and operate FRS radios for planned communications operations that safeguard human life or property”. Additionally, the Departments of Agriculture and The Interior have policies limiting the use of FRS radios. There is a viable option called Intra-Squad Radio (ISR). These radios are used by the United States Marine Corps (USMC) for tactical communications and the NIICD has been given authorization to operate on the frequencies.
Non-Federal Forest Firefighting AgenciesThe following frequencies may be authorized to fixed, land and mobile stations operated by non-Federal forest firefighting agencies on a secondary non-interfereing basis. See: NTIA Manual Chapter 4 US Footnotes US8 and 47CFR90.265(c) West of the Mississippi River these frequencies are also used for air-to-ground and/or the local nets of National Forests.
