    They didn’t really specify what radio signals. Often satellite communications may be interrupted, HF ham radio bands. Less of an effect on Earth-based radio transmissions as the atmosphere is somewhat a shield.

    If news is going to call out radio disruption in their headline, they should probably specify what, how widespread, etc.

      if you scroll down a little, it shows how an x.1.8 class solar flare caused a radio blackout a few days ago. it provides a heatmap and distribution of frequencies affected + the amplitude of the effect
