Abstract

There have been remarkable advances in affordable amateur-radio equipment, digital-communications protocols, open-access databases and analysis methods, since the 2015 partial eclipse over the UK.  Drawing on those advances, this article describes some impacts of reduced absorption and lowered F2 critical frequency (foF2) on HF propagation during the 14 October 2023 eclipse over North America.
