Don't forget also that most of the static on your radio is generally caused by the sun in the first place. If the sun didn't exist our radios would
have very little to almost no static on them. AM would still crackle from earthly causes like lightning and man made interference, but FM would almost
be silent w/o the sun causing its burps and radiation.
Static on a radio is caused by a few things, the sun itself, earth noises, man made, and internal static caused by the receivers sensitive front end
Usually the sunspots effect the lower VHF bands the most but it's well known to cause loud strange sounding static on shortwave bands and could cause
those same effects on the higher AM broadcast bands.
I have noticed this effect quite a bit these last few years. I am an avid shortwave listener and radio electronics has always been one of my favorite
hobbies. These last years just listening to channels w/o any signals and only static is interesting because you can almost hear the sun. Sometimes the
flairs are so powerful that the static is strong enough to make the signal strength meter on my radio go half up above its normal 0 point.
From my experience flairs tend to sound almost like digitized static like it's grainy and blotchy sounding where as regular static just sounds like
If I recall correctly this is how NASA studies the suns activity on radio bands by simply taking readings of static strength on the upper UHF
Interesting topic, hope some others can fill us in.
