(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) Information on the channels the law enforcement net occupy is no longer available as Channels 10-16 are not shown on the documents obtained.

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.
