A Long Overdue Review of Gray Line Propagation on the Low Bands
Carl Luetzelschwab, K9LA, will trace the history of gray line
propagation and theorize on a problem with the current explanation that
propagation along the terminator is efficient. He will offer an
alternative explanation.
Are We Headed Into Another Maunder Minimum? What Does That Mean For Propagation?
K9LA discusses the various parameters that indicate we may be entering
another Grand Solar Minimum (GSM). He will also discuss two possible
scenarios for HF propagation if a GSM does occur.
