out of large circle ionospheric propagation

Steve’s features consisted of a month-by-month look at each HF band in turn, showing the reader the propagation modes behind each band and explaining some of the technicalities of ionospheric propagation.

The primary mode of ionospheric propagation during the contest was meteor scatter enhanced by the Geminids meteor shower.

In one embodiment, one or more ionospheric propagation effects are estimated by using a phase comparison between an upper sideband and a lower sideband of a GPS M-code signal.
