Once again, it’s time for some of the best long-range DX openings of the year. With autumn right around the corner, the season for radical improvement in radio propagation conditions is beginning. This is the time to ensure that you finish any antenna projects, double-check your coax, ladder line, and grounding system. The DX “hunting” season is opening this month! Let’s get right to the exciting shortwave (high-frequency, or “HF”) propagation conditions starting in September.
By late September, the Sun will be directly over the equator. On the Autumnal Equinox (September 23 at 01:03 UTC), everywhere in
