All park repeaters are 20 watt solar powered repeaters and are capable of analog and P25 digital operation. Protection rangers have the ability to transmit encrypted when needed but generally operate in the clear. All park employees are issued radios for safety.
Listings are shown as: Repeater Output/Repeater Input. All repeaters transmit the input tone on the output frequency.
- North - 166.3250/166.9250 CTCSS 167.9 - NAC 167.
- Located on Mt. Washburn and covers the northern mountains to Mammoth, Canyon Tower, and portions of the north and northeast area of the park.
- Lamar - 166.3750/166.9750 CTCSS 192.8 - NAC 192.
- Most likely on Mt. Washburn, south of Tower & north of Canyon Village. Covers Lamar and northeast portions of the park.
- Druid Peak - 166.3750/166.9750 CTCSS ? - NAC 192.
- Located east of the Larmar Ranger Station and due north of the southernmost point on the road from Mammoth to Cooke City. This is a new repeater installed late 2014 or early 2015. This could be a relocation of the repeater on Mt. Washburn, in which case the CTCSS tone and NAC would be the same as the "Larmar" repeater above. This is the most likely scenario. It could also be an addition to the net, in which case the CTCSS tone and NAC need to be determined.

Park Unit Designators
- 1: Park Superintendent's and headquarters staff including 2 deputy superintendents; chiefs of the divisions of interpretation, maintenance, resource and visitor protection; and administrative functions.
- 2,3,4: Interpretive rangers, research, resource management (foresters, forestry crews, biologists, historians, archaeologists, geologists, air & water quality specialists, wilderness managers) with 2 being the north district, 3 the east district and 4 the south district. Most of these people use a three number designator with the second number representing functions. Some functions have more than ten positions so the numbers may be followed by the persons last name. Example: "462 Smith" is a employee with the last name of Smith who works for 462. The Interpretive Division has different geographical districts than protection and maintenance with those being: West (Grant, Madison, Lake and Old Faithful) and North (Canyon, Mammoth and Norris).
- 5, 6, and 7: Division of Resource and Visitor Protection. Protection includes these functions: law enforcement, structural/wildland fire protection, EMS and search and rescue. The first number of protection ranger's designators are issued according to the area of the general area of the park they work in with 5 for north, 6 for east and 7 for south.
- 9: Maintenance Division. This includes roads, trails and building maintenance; and water/waste water, solid waste, fleet maintenance, horse/mule care, crafts, carpentry, painting, plumbing, electrical; boardwalk and trail maintenance. It is unknown how each person is identified. This division's districts are: North, Tower, Beartooth, Canyon, Lake, Grant and West. Each district has a combination of the trades to handle what exists in each district.
- 700 Series: Base stations. This is derived from the callsign of the park, "KOF700." 700 is the dispatcher. The most often used functional base stations are:
- 700 Bravo= Backcountry Desk,
- 700 Charlie= Chief Ranger's Office
- 700 Echo= Chief of Maintenance Office
- 700 Fox= Fire Management Desk
- 700 Lima= Law Enforcement Desk
- 700 November= Chief of Interpretation Office
- 700 Sierra= Park Superintendent's Office.
- 701 and up are base stations such as ranger stations, entrance stations, and the like. The Park Service is moving away from using these in favor of their names, i.e. "West Entrance" "instead of 702, "Bechler Ranger Station" or just "Bechler" instead of 731. One that may still be in use is "702 Papa," which is the West Yellowstone PD. The stations can sign off using their callsign, e.g. the Bechler Ranger Station would sign off as "KOF731."
