The HF Radio Activity Group started over 10+ years ago with a small group of radio operators, W3FF, W8YCM and more. This group of radio operators would meet every day on a specific set of frequencies across multiple HF bands.
The purpose is twofold, first to determine what the propagation is in real time for that day, for no other reason than curiosity about radio. The second reason is to have fun using amateur radio.
