zeitgeist57 Posted August 15, 2010 Report Share Posted August 15, 2010 Just a wierd observation - when I listen to the AM radio, I can guarantee when there is a thunderstorm within a 50 mile radius just from the static/crackle that comes across the radio everytime lightning flashes. Did anyone else notice this before? Just had that observation recently when driving through a storm, listening to a game... FYI, I listen to 1460 The Fan for Indians games, and 820 WOSU for NPR...

justinwebb Posted August 15, 2010 Report Share Posted August 15, 2010 this has always happened i remember my dad listening to AM radio (which i hated) in the car and it would always crackle. You can also hear it change when at night they switch to a higher frequency to bounce off the higher atmosphere Quote Link to comment Share on other sites More sharing options...

Mensan Posted August 15, 2010 Report Share Posted August 15, 2010 AM radio stations must reduce their power at night. Also, disruptions can be caused by metal buildings, electric motors (alternators), and fluorescent lighting. Quote Link to comment Share on other sites More sharing options...
evan9381 Posted August 15, 2010 Report Share Posted August 15, 2010 I used to notice it going under some power lines while driving...used to love listening to talk radio when i was delivering pizzas...always something different. Music got boring as fuck after awhile...but mid afternoon when rush comes on i couldnt turn that shit off quick enough before i wanted to stab my ears Quote Link to comment Share on other sites More sharing options...

Tractor Posted August 16, 2010 Report Share Posted August 16, 2010 Electrostatic interference, totally normal. I stuck my radio on AM many years ago and never used FM again. As a side note about AM. During a meteor shower (such as the perseids going on right now) you can improve your meteor sighting chances by setting multiple radios around you on AM channels for cities say 100miles away that you can't normally pick up well. Just as a meteor is burning up the signal will increase from that station and direction. Quote Link to comment Share on other sites More sharing options...
Billiumss Posted August 16, 2010 Report Share Posted August 16, 2010 A lot of things can affect AM radio since it uses Amplitude Modulation. Even though I went to school for this stuff, this can explain it better than me: http://en.wikipedia.org/wiki/Amplitude_modulation Quote Link to comment Share on other sites More sharing options...
