Angeles National Forest (ANF - Forest #01)
Radio System
Channel Lineup
Most radios on the forest have 9 frequencies in common: ANF Channels 1 and 2 (Forest Net), ANF Channels 3 and 4 (Admin Net), two National Air to Ground frequencies and NIFC tactical channels 1 through 3. Each ranger district, and crews within each ranger district, may have different channel lineups, but they will usually have these nine in common. The variations between ranger districts and crews involve frequencies belonging to other agencies such as Los Angeles County Fire, San Bernardino County Fire, CalFIRE, and the Bureau of Land Management, as well as frequencies of adjacent National Forests. The agencies and areas that each ranger district interact with for mutual aid are different for each district.
ANF Channels 1 and 2 are called "Forest Net" and are used primarily for fire and emergency traffic. ANF Channels 3 and 4 are called "Admin Net" and are used for non-fire communications such as recreation, vegetation management, soils, road maintenance, engineering, wildlife, utility systems, building maintenance and grazing management . Channels 1 and 3 are simplex frequencies and channels 2 and 4 are repeated.
When users transmit on channels 1 and 3 using tone 8 (103.5 Hz) their transmission can be received by dispatch on the forest's 9 microwave linked remote bases. These remote bases are linked to dispatch located at Fox Field near Lancaster and the Forest Supervisor's Office in Arcadia. Most of these remote bases are co-located with repeaters and some are not. When someone communicates to dispatch on these channels it is not picked up by a repeater and receiving them requires being close enough to receive simplex traffic. On the other hand, if users transmit on channels 2 and 4 , the tone in use must match a repeater within range or their transmission will not be heard.
The 9 remote bases are located at: Fox Field (dispatch office), Arcadia (Forest Supervisor's Office), Frazier Peak, Warm Springs, Magic Mountain, Mt. Lukens, Blue Ridge, Johnstone Peak and Santiago Peak. Those remote bases that are not co-located with a repeater are: Fox Field, Arcadia, Warm Springs and Blue Ridge.
Intra-crew and communications on the Angeles NF take place on the Pacific Southwest Region's (R5) (all of California with the exception of a few small areas) project net of 168.6625 or on National Crew Net 163.7125. Tactical communications on the initial attack phase of fires is still being conducted on NIFC Tacticals 1-3. These channels as well as NIFC Tacs 5, 6 and 7 may not be used for intra-crew communications. The federal wildland fire and land management agencies (National Park Service, U.S. Forest Service, Bureau of Land Management and the U.S. Fish and Wildlife Service) are beginning to phase out the use of the NIFC tacticals for initial attack. The BLM and U.S. Forest Service are getting frequency allocations so that each Forest Service region and each BLM State Office so that each have a least three unique tactical frequencies separate from the six NIFC tacticals. The future use of the NIFC frequencies will be reserved for use on "National Fires." only. These are fires where a National Type I or Type II incident management team is in command. Region 5 has had three regional tactical frequencies for more than 20 years and are used when several large fires burn close to each other and the six NIFC frequencies are all being used to capacity. This occurs with some regularity in Region 5 as 40-50% of the fire workload of the U.S. Forest Service is in this region. Perhaps additional tacticals are in the works for R5.

Repeaters
The Angeles National Forest (ANF) radio system is comprised of 14 repeater sites situated on various mountain peaks in and around the forest which are linked to the dispatch center at Fox Field near Lancaster. Each repeater site functions as both a repeater and as a receiving antenna for dispatch.
Each repeater operates on the same input/output frequency pairs but uses a different CTCSS tone on the input. By selecting different tones users may activate different repeaters, choosing the one best suited to their location and communication needs. When a user activates a repeater by keying up on the appropriate input frequency and tone, their transmission is repeated only by that repeater. Other repeaters in the forest do not repeat transmissions from other repeaters. The input or repeater selection tone is not transmitted on the repeater output frequency, rather all repeaters transmit Tone 8 (103.5) on the output.
The nature of Bendix King radios used by the Forest Service is such that users may select a CTCSS tone independently for each channel by selecting a number on the radio's keypad. For the purpose of brevity the name of the repeater is not voiced, rather the CTCSS tone number is announced (e.g., "tone 9" instead of Pine Mountain or 100.0 Hz).

Eldorado National Forest (ENF - Forest #03)
The Eldorado National Forest does not use channel numbers to describe the frequencies it uses, rather it describes them by name. Channel plans vary based on the ranger district and function to which they are assigned. Recreation, fire, timber, range (grazing), wildlife, engineering and watershed are examples of functions. The names are shown below under "Description" for each channel.
Direct or simplex communications are not conducted on the forest's repeater nets such as Forest Net. Tactical frequencies are used instead. Almost all handheld radios in use by the Forest Service are the Bendix-King. These radios have 16 groups and 16 channels per group. Only one group can be used at a time. By eliminating the simplex operation of the 5 Forest Service repeater nets the forest uses, 5 channels are available for other frequencies.
