The North Pacific is considered to be above 37N and west of 150W, west to the Tokyo FIR at 165E, and includes the Anchorage FIR and Russian Airspace. Some checkpoints along the Aleutian chain are in HF range of remote relay stations; therefore, Anchorage controllers communicate directly with flights along much of their route. Tokyo Radio is the only other radio station using the North Pacific frequency groups
NP/Polar Routes: Anchorage ARTCC’s current radio voice capabilities in the Arctic CTA do not extend past N75°. Lack of satellite coverage in the polar region affects CPDLC coverage as well. Because of the lack of ATC communications available in the Polar region, SFO provides communications using the NP1 HF family as primary and the Barrow, Alaska LDOCF as a secondary means for these aircraft.

CEP (Central East Pacific): The Central East Pacific has composite route structures which primarily cover the areas between the Continental United States and Hawaii. It also covers the route structures between Canada and Hawaii. When assuming radio guard on CEP flights, flights will monitor the primary and secondary HF assignment and set the aircraft transponder unit on code 2000 (also called squawk Code)
San Francisco 3467 5643 8867 13261 17904 kHz
SP (South Pacific): Most flights traveling to and from the South Pacific operate during the mid-shift. Generally, the lower frequencies of the SP family are reliable during these hours. Several ground stations share this group: Brisbane, Auckland, Nadi, Tahiti, and San Francisco. Station interference is not normally a problem. Most flights leave SFO radio guard and enter Nadi’s guard. Nadi radio operators (ROs) occasionally work traffic well into the SFO guard area when atmospheric conditions make reading the flights difficult.

21985 kHzCWP (Central West Pacific): The frequencies of the Central West Pacific family cover a vast amount of territory. The boundaries of the Oakland FIR have neighboring control authorities and radio stations. San Francisco shares this frequency group with Tokyo, Manila, and Port Moresby. The West Pacific frequencies are divided into 2 groups. CWP- 1 generally works flights east of 170E and flights traveling between Honolulu and the Orient, and CWP-2 works flights in the Guam area, west of 170E.
