Update - Special Research Permits (501 to= 504 kHz=20 band)

Following representations made by the Radio Society of Gr= eat=20 Britain and negotiations by Ofcom with the Maritime and Coastg= uard=20 Agency, Ofcom has decided to extend the= period of=20 Notices of Variation (NoVs) to the licence for operation in th= e 501 to=20 504 kHz band until 29 February 2012. The maxim= um=20 effective radiated power (e.r.p.) limit is maintained at 10 dB= W (10 W).=20 Existing NoVs are due to expire at the end of February 2010.=
There have been no reports of interference and inv= estigation=20 has shown that a radiated power of 10 dBW is not likely to cau= se=20 interference. Moreover, NoV holders are permitted to operate= only=20 subject to causing no interference.
Special Research Permits under a Notice of Variation to= the Licence=20 are made available to holders of Full Amateur Licences on a ca= se by case=20 basis to applicants who can demonstrate a genuine interest in= =20 experimentation at these frequencies and provide adequate supp= orting=20 documentation for assessment.
Due to the usage of the spectrum around the 500 kHz bands= ,=20 applicants should pay special attention to demonstrating techn= ical and=20 operational competence in terms of transmitting within the fre= quency=20 band and Effective Radiated Power (e.r.p.) parameters agreed= with Ofcom.=20 Previous experience at 73 kHz as well as 136 kHz will be consi= dered=20 desirable in this respect to ensure adequate steps are taken= to limit=20 any potential interference.
