HF radiofax (weather fax) broadcasts for the Pacific Ocean: when each station transmits its weather charts, with frequencies, on the timelines of your cities and in your own time zone.
The Pacific is the largest stretch of open water on Earth, and radiofax remains a standard way for yachts and fishing boats to get weather charts far from land. This calendar covers NOAA’s three Pacific stations — Point Reyes in California, Kodiak in Alaska and Honolulu — plus JFX Kagoshima for Japanese fisheries, Shanghai and Guangzhou for the China seas, Seoul for Korean waters and Valparaíso for the coast of Chile and the South-East Pacific.
The Pacific spans time zones from UTC−10 in Hawaii to UTC+9 in Japan and Korea, which makes a UTC schedule especially hard to follow aboard. Times here are the transmission windows of the EiBi shortwave schedule, converted to your local time; for NOAA and Kagoshima each window lists the charts it sends — surface analyses, wind and wave forecasts, sea temperatures and satellite pictures — with a link to the station’s schedule. Frequencies are the assigned ones: tune 1.9 kHz lower in USB.
Select a transmission window to see its frequencies, the charts and the transmitter, with a link to listen on an online SDR receiver.
NOAA Point Reyes (NMC), north of San Francisco, transmits on 4346, 8682, 12786, 17151.2 and 22527 kHz with charts for the North and East Pacific.
Honolulu (KVM70) uses 9982.5, 11090 and 16135 kHz for the central and South Pacific; Kodiak (NOJ) uses 2054, 4298, 8459 and 12412.5 kHz for Alaska and the Gulf of Alaska.
JFX is the Japanese fisheries radio station that sends sea surface temperature, current and weather charts for the North-West Pacific, many times a day and on several frequencies.
The frequencies listed are the assigned ones. Tune your receiver 1.9 kHz lower in USB and decode with radiofax software such as fldigi.
