In my quest of learning electronics, I try to understand radio propagation. All of the numbers, terminology, and charts can be somewhat overwhelming. Is there a simple, quick reference to better understand the HF progation numbers? 1. K-Index — 0-9. Overall, low is better. Some VHF operators like to see an increasing K Index, because aurora […]

The equinox (around March 20 and September 22) brings us better DX propagation, especially the upper bands. The ten meter band (28000 to 29700 kHz) tends to be at its best near the spring or fall equinox. In fact, the equinoxes are when geomagnetic storms are the strongest. These strong geomagnetic storms can actually be very disruptive to the […]
