(1) The park's air to ground frequency is also designated National Air to Ground 55. There is no record of AG 55 being assigned to any dispatch zone in the country. On a case by case basis, NIFC can assign it to extended attack incidents, but cannot do so if interference to Yosemite NP will result.
(2) The last three frequencies (in Channels 12 - 16) are federal government nationwide lower power itinerant frequencies that can be used by any federal agency at any time and location and no one agency has an exclusive authorization. They are commonly used as tactical frequencies in National Parks, especially 168.6125.
(3) It is believed that Channels 15 and 16 may be programmed for digital operation. This is yet to be confirmed. This is our best conjecture given these channels are duplicates of Channels 13 and 14.
It is not known how use of the law enforcement net is determined as protection rangers are heard on the Park, Valley and Law Enforcement Nets. Based on listening it appears that most law enforcement and search and rescue communications in the Valley District use the law enforcement net. The bulk of the protection traffic in the remaining districts is carried on the park net.

Repeaters transmit the input tone on the output frequency.
