5 MHz Near-Vertical Incidence Skywave

A paper 'Comparison of propagation predictions and measurements for
midlatitude HF near-vertical incidence sky wave links at 5 MHz' by
Marcus Walden G0IJZ has been published in the Radio Science journal.

This journal carries original scientific contributions on all aspects
of electromagnetic phenomena related to physical problems. Coverage
includes the application of electromagnetic techniques to remote
sensing of the Earth and its environment, telecommunications, signals
and systems, the ionosphere, and radio astronomy.

Radio Science is a subscription publication, however, a PDF of the
article has been made available on the website of Essex company
