In fact, the 'D' layer acts as a\nreflector, rather than an attenuator at these frequencies. Cosmic\nbackground radiation maintains sufficient 'D' layer ionization at night.\n\nHowever, your post reminded me of project INSPIRE, which was a plan to\ntransmit VLF signals from the Space Shuttle back in 1992 using a pulsed\nelectron gun in the payload bay. Details on project INSPIRE can be found\nhere:\n\n http://theinspireproject.org/index.php?page=faq\n\nI'm not sure how this would penetrate the ionosphere except through brute\nforce.\n\nNevertheless, compatible receivers are simple to build and readily\navailable.\n\n\n73, de John, KD2BD\n\n--\nVisit John on the Web at:\n\n http://kd2bd.ham.org/\n\n\n\n \n_______________________________________________\nSent via [email protected].
