1 The park's air to ground frequency is also National Air to Ground 55. There is no record of it being used anywhere in the country. It might be used as an air to ground on extended attack incidents after assigned by NIFC. NIFC cannot assign it in a wide area around Yosemite NP as it has been assigned to this park.

2 This information is not provided in interagency frequency directories.

3 The last three channels (12 - 16) are federal government nationwide itinerant frequencies that can be used by any agency at any time and location. Agencies do not have exclusive use of them. They are commonly used as tactical frequencies in National Parks, especially 168.6125.

4 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.
