Early last week I em= ailed OFCOM but I have still not received responses:

My questions were:

Am I correct in assuming that radi= o amateurs may legally experiment in the old 73kHz band as long as output power is less than 72dBuA/m at=20 10m? This is the limit for licence-exempt inductive devices.

Also, please can you confirm that no licence is needed to op= erate below 8.3kHz (assuming no harmful interference to services abo= ve 8.3kHz). This part of the spectrum is unallocated.

Thanks
