Hi Tom, David,
I'm not aware of a functional "Tesla Antenna" concept. The mentioning of the Kiruna site suggests that those low frequency carriers might be have been created by ionospheric heating, where a powerful AM-modulated HF transmitter is used to modulate the ionospheric conductivity. In analogy to the "Luxembourg effect" where the modulation is transferred to other MF or LF signals, they can also generate detectable ELF emissions by deflecting the DC polar electrojet current. Similar experiments have been reported by the HAARP facility (Gakona AK), and the method has been suggested as a means to communicate to deeply submerged submarines. 73, Markus, DF6NM -----Ursprüngliche Mitteilung----- Von: DK1IS <[email protected]> An: rsgb_lf_group <[email protected]> Verschickt: Sa, 10.

most interesting! - Could you give some more information about QTH, TX and "Tesla" antenna? Tu es 73, Tom, DK1IS Am 09.02.2018 um 21:44 schrieb David Hine:
