Radio Channels

There are 15 total channels used in the park for radio communications in three groups: Admin Net channels, Common-Use channels, and the Portable Repeater channel.

The following channels form what is known as the Admin Net, which is the Park’s main radio system. Its primary purpose is for emergency and safety communications and secondary for general-purpose use where employees can communicate with each other to help perform their duties.

Channel Name  Area Covered
Paradise Nisqually Entrance to Paradise. Longmire, Upper Stevens Canyon Rd.
TWoods Longmire to Eatonville.
Gobblers Nisqually Entrance to Tahoma Woods, Southwest backcountry
Packwood Skate Creek Rd., Packwood, Box Canyon to Backbone Ridge on Stevens Canyon Rd.
Shriner Ohanapecosh to Cayuse Pass, Chinook Pass, Sunrise, Lower Stevens Canyon Rd.
Crystal Cayuse Pass to Enumclaw, White River, Sunrise Road, Northeast backcountry
Sunrise Sunrise area
Fremont North backcountry, areas above Sunrise
Tolmie Carbon River, Mowich Lake, Eatonville, Enumclaw, Northwest backcountry
West Direct Local-area use, Westside ranger district
East Direct Local-area use, Eastside ranger district

The first nine channels are ‘repeater channels’, and the name designates the location of the repeater. Repeaters are used to take your transmitted radio signal and spread it out from the repeater’s location over a wider area so you can communicate with others in range of the repeater.

All of the eleven Admin Net channels receive on the same frequency. Because of this, you will hear any and all radio traffic that is within range of your radio, regardless of which Admin Net channel you might be on (i.e. your radio is on PARADISE but you’re hearing radio traffic from others on SHRINER).

DIRECT should only be used when it is ineffective to use repeater channels. This can happen when communicating a very short range (less than 200 feet) away from the other party (i.e. letting a road crew member know you are right behind their machinery before you pass them) or if a repeater fails. DIRECT should not be used for routine communications – if you need to communicate short-range, use a common use channel instead.

The next three channels COM 1, COM 2, and COM 3 are known as both common-use and off-net channels, meaning that they are stand-alone channels that are not a part of any radio system.

COM channels are for general-purpose use between individual units in the field when in range of each other.

Note: The ‘Portable Repeater’ channel is used when temporarily deployed during incidents for providing coverage in a specific area and/or for operations that require frequent radio usage and not tie up the Admin Net (such as helicopter operations for a wildland fire or SAR incident).
