Re: LF: Fwd: Questions about 73kHz and sub 8.3kHz

Roger,

     I am not sure of the relationship U.K. amateurs have with OFCOM, but I found that here in the U.S. it is better NOT to ask. If you ask a bureaucrat they will naturally fall into CYA mode and give you the most restrictive and conservative interpretation of the rules. Remember, it is easier to ask for forgiveness than it is to ask for permission!

Still awaiting OFCOM responses after about 8 working days since first email sent.  Will post reply here, assuming they ever manage one. I am not hopeful.

Subject: Questions about 73kHz and sub 8.3kHz
To: licensingcentre@ofcom.org.uk

Early last week I emailed OFCOM but I have still not received responses:

My questions were:

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

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

Thanks

Roger Lapthorn
