Hi all,

Soon, i'm going to make a short VLF transmit test at 2.99 kHz, which is below 8.3 kHz and thus legal :-) As in every (!) VLF transmission i've done so far, i'll use the class D transmitter which has a rectangular voltage form applied to the antenna system. Maybe i'll just leave the resonance as it was in the previous tests, which is legal too ;-) I do assume that my harmonic power, radiated on 8.97 kHz (as well as on 26.91 kHz, 80.73 kHz and so on), will not cause interferences to commercial users of the spectrum, such as ALPHA RSDN or WX researchers.
All in all it means that the transmission on 2.99 kHz is legal.

Very fine :-)

73, Stefan/DK7FC
