Ofcom announces special research permits
for
501 - 504 kHz
The UK regulator Ofcom has decided to permit a limited number of Amateur
Radio Full licensees to operate under a Special Research Permit between
501 and 504 kHz for a 12 month period commencing from 1 March 2007.
This follows representations made by the Radio Society of Great Britain
and negotiations with the Maritime and Coastguard Agency.
Special Research Permits under a Notice of Variation to the Licence may
be made available to holders of Full Amateur Licences on a case by case
basis to applicants who can demonstrate a genuine interest in experimentation
at these
frequencies and provide adequate supporting documentation for assessment.
Due to the usage of the spectrum around 500 kHz, applicants should pay
special attention to demonstrating technical and operational competence
in terms of transmitting within the frequency and Effective Radiated Power
(e.r.p.) parameters agreed with Ofcom. Previous experience at 73 kHz as
well as 136 kHz will be considered desirable in this respect to ensure
adequate steps are taken to limit any potential interference.
Ofcom will monitor any interference reports with a view to limiting numbers
in the use of the band if necessary. In general, considerably lower e.r.p.
levels than that permitted in the 136 kHz band are likely to be favourable
and this will only be permitted where it can be demonstrated that increased
powers are necessary for research. On no account will an e.r.p. level
of greater than – 10 dBW be permitted under any circumstance.
