K6EEG Earth and Space Science Beacon
A 24-hour voice beacon on 927.300 MHz (narrowband FM) from San Francisco, reporting the conditions radio amateurs care about: space weather and HF propagation, tropospheric ducting, satellite passes, DX activity, weather, tides, air quality, and earthquakes. It's also a propagation beacon: its steady carrier tells listeners around the Bay Area and beyond how 33 centimeters is getting out.
The latest report and current conditions appear below, updated twice an hour.
