Re: LF: Below 9 kHz

[WarmSpgs@aol.com]

Magne raises a good point.  One needs to consult the regulations in one's 
home country.  Over here, frequencies below 9 kHz are not regulated, but the 
ITU requirement is interpreted to mean harmonic energy appearing on 
frequencies above 9 kHz must be kept below field strength levels specified in 
other parts of our FCC's rules.
This makes the sub-9 kHz region ideal here for earth dipole experiments, and 
even conventional antennas, but only if one takes adequate harmonic 
suppression measures.
