Spaceweather -- A place to sign up for the W4HM Daily HF Radio Wave Propagation Forecast


About Spaceweather
English (USA)

Welcome to the W4HM Daily HF Radio Wave Propagation Forecast.

This un-moderated email reflector has also been created as a meeting place where one can ask questions about and discuss any subject concerning solar, space and geomagnetic weather as well as HF radio wave propagation.

I have extensive education in and forecast experience concerning solar, space and geomagnetic weather, as well HF radio wave propagation. However I still do not know everything about this diverse subject.
