Brian,

The official line is, I believe, that any form of communication by
electricity, wireless or whatever you call it below 9kHz does need a permit
from OFCOM as such communications are covered by the Wireless Telegraphy Act
and its amendments. Others may have a more informed view.

Unofficially, I am taking the view that earth-mode at 4W on sub-9kHz is
unlikely to cause a problem, so I'm carrying on my tests whilst waiting for
an NoV (3 months now waiting patiently).  If I decide to run 100W or more in
these tests then I think I should wait for official clearance. Likewise I
think others in the UK considering radiated tests using high power on
8.97kHz or thereabouts are waiting.

I'm unsure of lightbeam transmissions: clearly we don't need NoVs to shine
torches, use a microwave oven or turn on the headlights, but maybe OFCOM
would require it if asked, HI.

73s
