Angeles National Forest (ANF - Forest #01)
Radio System
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 Palmdale. 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 nature of Bendix King radios used by the Forest Service is such that users may select a CTCSS tone by selecting a number on the radio's keypad. As a result, most users refer to the CTCSS tone by its number (e.g., "tone 9" instead of Pine Mountain or 100.0 Hz).
