Jim, "It was possible to hear "whistlers" from storm centers long before you could hear the thunder."
I doubt the whistlers you heard was from a storm that was close enough to hear the thunder: "Very low frequency (VLF) radio waves shoot past the ionosphere and into the next region of space, the magnetosphere. Here, the atmosphere is completely ionized. The Earth's magnetic field controls the motions of charged particles, creating channels of ions aligned with the horseshoe-shaped magnetic field lines. These channels trap VLF radio waves, guiding them between opposite hemispheres along a path that reaches up to 15,000 miles from the surface." http://news.stanford.edu/news/2011/may/robert-helliwell-obit-052011.html I visited the lab when I was a freshman (before the advent of dirt) as part of the tour they gave incoming engineering students. -Rex- K1HI Rex Lint Merrimack, NH WWW.QRZ.COM/db/k1hi ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
