GB3VHF to close down in December 2008


After nearly fifty years of near continuous service from the 
transmitting station at Wrotham in Kent (JO01DH), the 2 metre beacon 
GB3VHF will fall silent towards the end of December 2008.

For a good few years the beacon enjoyed the site facilities at Wrotham 
by means of a ‘peppercorn rent’. At this time the site was owned and 
operated by the amateur radio friendly BBC.

During the 1990’s the site and facilities was acquired by Crown Castle 
Transmission Ltd and around that time the RSGB were involved in 
negotiations with site providers such as Crown Castle, NTL and Pye 
Telecommunications Ltd, with regard to site sharing fees that the site 
sharers thought more accurately reflected the true cost of accommodating 
and providing mast sharing facilities for amateur radio equipment, such 
as beacons and repeaters. At that time it was decided that ‘peppercorn 
rents’ would cease and that site sharing costs would rise to meet a 
substantial proportion of the commercial rate applicable at that time. 
The rent increases were applied on an escalating scale and it was found 
by many groups that the increases could not be met and consequently many 
groups had to quit these sites. One example of this at the time was the 
70cms repeater GB3NK which used to sit alongside GB3VHF. Once the site 
rental had reached a certain level the Kent Repeater Group could not 
afford to pay for any increases and so the repeater site sharing 
agreement was terminated, and the repeater was removed from the site. 
This story was a common feature of repeaters across the UK and most 
keepers removed their units from these premier sites.

The RSGB continued to pay site rental for some beacons, which were 
considered by the site owners at that time to be used for scientific 
purposes (they still are!!). However, gradually the owners applied 
greater site rental increases until such a time that the site rentals 
became unsustainable. This is now the situation with GB3VHF and the 
society has decided that they are not prepared to pay further increases 
to the new site owners Arqiva Services. The RSGB have decided that 
future site rentals would mean that the beacon keeper would have to pay 
50% of the 2009 site rental and to pay 100% of the site rental in 2010. 
As the figures involved are substantial, this is considered to be a 
major expenditure and consequently not within the possibility of one 
person (or even a group) to pay. One answer could be to seek donations 
from users, but the task of achieving this on an annual basis and the 
probability of not being able to achieve the required figure every year, 
together with ever increasing annual costs make it a formidable task. 
The financial liability would put the beacon keeper in a very risky 
position indeed.

Another consideration which has led to the decision to close, has been 
that of the problems with gaining access to the beacon site which have 
been made very much more difficult during the past year. Extensive 
security measures have been put into place by the site owner, thus 
making ‘out of hours’ access a difficult process that cannot always be 
guaranteed 24 hours a day. It is a licensing requirement that the beacon 
can be closed down in an emergency at any time day or night.

These two major problems have led to the only viable decision, and that 
is to cease operation of GB3VHF from the Wrotham site. This is very 
regrettable as the beacon was completely modernised only two and a half 
years ago and turned the beacon into one of the most advanced units of 
its kind in the world.

The amateur radio community both in the UK and Europe have welcomed the 
new beacon facilities such as it’s GPS locked on-air frequency accuracy, 
on/off CW keying, JT65B and precise timing. Comments received have been 
very favourable indeed, and I know that the beacon will be considered a 
great loss to VHF users in many parts of the UK and mainland Europe. 
During the last two and a half years the beacon has been received in 
more than seventy locator squares and the greatest distance being 
Tunisia in locator JM56HJ at 1849 kms.

As for the future, attempts will be made to secure a new viable and 
sustainable site that may hopefully provide coverage similar to that 
currently enjoyed. However, such sites that don’t involve enormous 
rents, these days are very difficult to find, and it is likely that a 
suitable site to relocate the beacon to will be some way off.

It is hoped that the beacon will return to the air in the future so that 
an ‘old friend’ will once again be heard on 2 metres.
