Walker County Fire
Most Walker County fire departments are dispatched by 911 Control on 159.39000 (167.9 PL) over three transmitters at different sites in the county. A different PL tone is used on 151.28000 to access the receiver of each site. A courtesy tone (or lack thereof) following each transmission indicates which site is in use.
Site | Tone In | Courtesy Tone |
---|---|---|
West | 156.7 PL | none |
South | 167.9 PL | 1750 Hz (high) |
North | 179.9 PL | 1000 Hz (low) |
Automatic station identification transmissions begin with alternating 880 and 480 Hz tones. A prerecorded voice ID of "WQQG392" is followed by "north", "west" or "south", indicating which transmitter is identifying. The courtesy tone for that site is sent at the end of the transmission.
Certain repeater site conditions can also trigger prerecorded voic alarms such as "door open", "door closed", "generator on" and "generator off"; these announcements take the same format as the IDs, but with the condition in place of the call sign.
Tone Outs
Each fire department dispatched on 159.39000 has a unique A tone; the B tone 788.5 Hz is common to all. County-wide paging is achieved by sending just an eight-second B tone.
Department | Tone A (Hz) | Tone B (Hz) |
---|---|---|
Argo | 349.0 | 788.5 |
Curry | 457.9 | 788.5 |
Jasper | 539.0 | 788.5 |
