Thread-topic: LF: Re: Sub-9kHz NoV progress
John,
 
I guess this applies only for signals above a certain level, probably the same as for unwanted radiation (harmonics, spurs) of "legal" transmissions.
In Belgium it is 0dBm below 30MHz and -26dBm above (not stated wether this is TX output power or ERP).
At VLF only ERP makes common sense (otherwise any audio amp would be illegal).
Taking into account what efforts Stefan had to do to get 1mW ERP any "back yard" experiment running reasonable power will far below this level.

BTW: below 9kHz is not regulated in Belgium, so UK dreamers band fans can consider a holiday in Belgium ;-)

Some say a NOV is not necessary on this QRG.

It depends on the country.  The last time I asked, the Crown monopoly on UK radiocommunications (which is modified by granting licences) did apply to this part of the spectrum.  Other adminstrations may have different laws.
