To clarify the 73kHz permit situation once and for all, for the benefit 
of Mal and anyone else who is confused, the RSGB has never 
issued Notices of Variation for the 73kHz band. These were, and still 
are, issued by the Radiocommunications Agency. I can appreciate 
there may be some confusion as, in order to speed up the original 
applications, the RSGB offerred to help the RA by processing the 
original paperwork. The NoVs were, however, issued by the RA.

When the life of the band was first extended, this was done on the 
RA's insistence that no new NoVs would be issued.

The recent three-year extension and additional Novs were the result 
of a detailed proposal made by the RSGB. To quote the RA's press 
release:
-------------

The reasoning behind the Agency acceding to this request from the Radio 
Society of Great Britain (RSGB) is as follows: 

 Experimentation on 73kHz has been slower than anticipated due to the 
high-noise floor towards the top end of the allocation. 

 There have been recent developments within Europe to allow reception 
on 73kHz and transmission on 136kHz 

 Additional work is being undertaken on how propagation is affected by 
the current enhanced solar flare activity and an opportunity to experiment 
with large antennas has been provided by the de-commissioning of the 
Decca Navigation System.

---------------

I think this shows quite clearly that the Society is, and always has 
been, very much in favour of as many people as possible 
experimenting for as long as possible on this interesting band. What 
a pity that of the several hundred Novs issued initially, only a handful 
were ever used.
