    It seems like there have been more blackouts on HF since the sunspots started coming back.

      @ham_bitious Sunspots=blackouts-propagation. We don’t get propagation without noise.

      The key for hams is that the noise drops at night, but the ionosphere takes more hours to deionize itself, and the propagation persists for a few hours.

      But you don’t get reach without noise.

        I thought flares caused the blackouts and sunspots just improved propagation
