How does sunspot activity affect radio reception?

Answer 1

It effects our technology.The blinding light spurts in
front of our major communication systems.Knocking
of the signals from one technical source to another.
It's just that simple.They have found minor adjustments remedy the communication systems as possible from this natural
occuring phenonemon .There's nothing to worry about
...other then maybe crazies.That may be "infected" from
the logical occurances...Like example "Men were seen
running about on every limb.They were said to gather upon a hill
in groups, where they were all said to start howling at the moon"
Thus these men became known as warewolves....lol

Answer 2

The higher the sunspot numbers, the better the propagation of short wave signals. Right now we are at a spot minimum and shortwave communications is difficult at the higher frequencies and only reliable at certain times. At the spot maximum, shortwave communications is reliable pretty much 24 hours a day.
