Hi All,
As someone who used to be professionally engaged in negotiating with the
aforesaid regulator in its many incarnations/reincarnations prior to
becoming Ofcomm, believe me it ain't easy!
However, it is appreciated that each country and legislation, have their
own (sometimes peculiar) approaches to the problems posed by demanding
spectrum allocation.
Some of us are extremely fortunate to have the talented and tenacious
advocates that achieve so much against often quite incredible pressures
from other interests.
What is often forgotten is that some of these guys are doing this work
unrewarded, in their own time and sometimes at odds with the commercial
interests of their employers!
For obvious reasons they cannot say this stuff on their own behalf but
maybe, at this seasonal time we can all raise a glass and say THANK YOU!

Yes , we seem to of done quite well considering , I think the only
gray area was the approach / marketing of the allocation where as
operations where initially viewed as a follow on from 136 and as
such its possible that it did not attract a wider response, where
as it very soon became apparent that the band was more similar
to 1.8 MHz in terms of coverage and the requirements for large
arrays and power level did not materialise and in fact the compact
array has provided most if not all of the Dx worked on the band to
date , ''even'' Gus is using a antenna system that is within
the boundary of his own house and is still fractional compared to
the wave length, once I had modified my old 80 ft total inverted L
with loading coil and top capacity section , 50 to 100 watts
provided amazing coverage and performance on 1.8 & 3.5 also
increased significantly .. unintended consequence !
Back in the 1970's a old friend of mine , long passed, who
introduced me to vhf radio 2 & 4 mtr am G3SX always maintained
that the 500 K / 600 mtr band was the original armature band in
the period between the 1914/1945 war's and the marine service,
once spark had been phased out , took over the band and forced the
armature operation hf to the new fangled 1.8 and higher
So may be the tapping gang where just keeping it free for us
after all .. 70 years was long enough !

Congrats to All on MF in G-Land. I would like we had RSGB and OFCOM in
Germany.
Merry Christmas

FYI 16|12|09
Update - Special Research Permits (501 to 504 kHz band)
Following representations made by the Radio Society of Great
Britain and negotiations by Ofcom with the Maritime and
Coastguard Agency, Ofcom has decided to extend the period of
Notices of Variation (NoVs) to the licence for operation in
the 501 to 504 kHz band until 29 February 2012. The maximum
effective radiated power (e.r.p.) limit is maintained at 10
dBW (10 W). Existing NoVs are due to expire at the end of
February 2010.
There have been no reports of interference and investigation
has shown that a radiated power of 10 dBW is not likely to
cause interference. Moreover, NoV holders are permitted to
operate only subject to causing no interference.
Special Research Permits under a Notice of Variation to the
Licence are 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 the 500 kHz bands,
applicants should pay special attention to demonstrating
technical and operational competence in terms of transmitting
within the frequency band 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 and also consider
limiting numbers if necessary in reviewing operation in the
band. On no account will an e.r.p. level of greater than 10
dBW be permitted under any circumstance.
The standard application form (OfW306) for a Special Research
Permit can be downloaded at:
http://www.ofcom.org.uk/radiocomms/ifi/licensing/classes/amateur/applications/ofw306.pdf
A fresh NoV will automatically be issued to existing NoV
holders; new applications are not required in this instance.
Should a fresh NoV not be required or if you are in possession
of an NoV which is not required, please inform the Ofcom
Licensing Centre stating your name, call sign and Licence
number preferably by e-mail to [email protected] or
alternatively by post to the address at the end of the text.
Form OfW306 is also available on request from the Ofcom
