PS: There is no power limitation in that VLF range below 8.3 kHz, it is=20
not even amateur radio by definition so we do not act as radio amateurs.=20
Actually everyone can transmit in that range, at least in DL or other=20
countries where no NoV is needed.

So actually, i can radiate several 10 mW ERP at 12 kHz as long as i am=20
TXing at 4 kHz fundamental frequency, because i do not cause=20
interferences? :-)) Isn't that nice? :-)
