Here we go again, Chicken Little.
I used to be in communications in the Air Force. I was stationed at a location in the early 70s where an atmospheric SID (sudden ionospheric disturbance) occurred.
It shut off all HF communications. It took out everything we had up to UHF frequencies and even degraded Microwave comms. Supposed to happen on an 11 year sunspot cycle.
Higher frequencies are less affected, particularly when they don’t involve transmission via the ionosphere.
Hide everyone...here she comes!
