GB2RS Main News for Sunday 25th February 2018
The news headlines:
* New RSGB ETCC Chair appointed
* Bodleian talk on What is Wireless
* NRC to open 6 days a week
The RSGB is delighted to announce that Andrew Barrett, G8DOR has been
appointed as the new Chair of the Emerging Technology Coordination
Committee, or ETCC, for an initial period of three years. Andrew is
the current Vice-Chair. The ETCC functions to develop and enhance the
UK amateur radio repeater and data communications networks and to
promote the introduction and rollout of appropriate new technologies.
They receive, vet and advise on all proposals in respect of analogue
or digital voice repeaters, TV repeaters and data communications
systems, passing the finalised documents to Ofcom for issue. The RSGB
would like to thank John McCullagh, GI4BWM for the enormous level of
work that he has put into the role of ETCC Chair for over 12 years,
particularly in his work with Ofcom.
A forthcoming lecture at the Weston Library, Broad Street, Oxford may
be interesting to radio amateurs. Jacob Ward, a Bodleian Libraries
Byrne-Bussey Marconi Fellow will be speaking on What is Wireless and
will explores what happened to ‘wireless', from after World War II
to the birth of the ‘new' wireless in the 1980s and 1990s, by
exploring the imagination and imagery associated with wireless
communications by its biggest proponents: the Marconi Companies. The
talk takes place on the 6th of March from 5.30 to 6.30pm and is a
free public event. All are welcome. Tickets can be reserved via
tinyurl.com/GB2RS-0225-A

The RSGB is pleased to announce that the National Radio Centre,
located at Bletchley Park, will now also be open on Mondays. Starting
from Easter Monday, the 2nd of April, the NRC will now be open six
days a week, closing only on Tuesdays. NRC opening times run in
accordance to the Bletchley Park museum, 9.30am to 4pm in winter and
to 5pm in summer. Bletchley Park admission details are at
www.bletchleypark.org.uk. RSGB Members can gain free access to
Bletchley Park, including the National Radio Centre, by downloading a
voucher from the Membership Services area of the RSGB website,
www.rsgb.org/bletchley-park-voucher
An international amateur radio team that postponed a December 2017
DXpedition to the disputed Spratly Islands now plans to be on the air
in early March from Layang Layang Island, also known as Swallow Reef,
under Malaysian call sign 9M0W. The IOTA reference is AS-051. The
operation will be on the air on 160 to 6m using CW, SSB and digital
modes. While the Royal Malaysian Navy maintains a presence on the
reef, ownership of the Spratlys has also been asserted by the
People's Republic of China, Taiwan, Vietnam, and the Philippines in
addition to Malaysia. The Spratlys are Number 56 on Club Log's DXCC
Most-Wanted List.
Another RSGB 2017 Convention presentation has been added to the video
portal for RSGB Members to view. The talk is by Ian White, GM3SEK,
and called VHF-UHF DX – the Game of Decibels. In a talk aimed at
all technical levels, Ian explains that decibels are the ‘currency'
in which we measure our station's performance. We can count our gains
and losses, save our decibels or throw them away, and eventually find
our own answers to the age-old question, "what is one decibel really
worth?" Ian explains why we use decibels; why 1dB can be worth more
to VHF-UHF DXers than almost anyone else; and how ‘counting the
decibels' can point us to the next station improvement. Take a look
at www.rsgb.org/videos for this and many other talks.
Richard Lamont, G4DYA has been appointed to the joint role of Amateur
Radio Observation Service and Intruder Watch Coordinator. Richard has
been a broadcast engineer with the BBC, an editor of radio magazines
and a company director. He also knows his way around the ITU
Regulations. The RSGB welcome him to his new role. Richard succeeds
Mark Jones, G0MGX who we thank for putting a great deal of time and
energy into these activities over the last five years.

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO
on Friday the 23rd of February.
Despite warnings in the popular press that a massive solar flare was
likely to cause chaos on Earth, we managed to survive! In the event,
a coronal mass ejection, which was linked to the solar flare, caused
the K index to rise to five on Monday 19th, but conditions became
more settled from Tuesday onwards. There was DX to be had if you
looked for it. For example, ET3AA in Ethiopia has been very audible
on 18MHz around lunchtime. Otherwise, the Sun has been more settled,
with no visible sunspots and a solar flux index of 68 on Thursday –
that's just two points above what we can expect at absolute solar
minimum.
As this report was being prepared a large coronal hole was visible,
stretching from one solar pole to the equator. This might suggest we
could have unsettled geomagnetic conditions on Earth from around
Sunday 25th, although the NOAA figures don't support this. Next week,
NOAA predicts the solar flux index will remain around 70, so we can
expect maximum usable frequencies to remain similar, with daytime
band openings up to 17m and occasionally 15m. With night-time
critical frequencies remaining around 3MHz, bands much above 40m
remain mostly closed to DX.
And now the VHF and up propagation news.
It's a cold, high-pressure story this week, and although technically
this is a very strong high, the air underneath the temperature
inversion that these highs produce is cold and dry. This is not
particularly good at changing the refractive index of the air across
the inversion and implies that this is not really the best option for
Tropo. It is better than flat conditions, and could possibly help out
early in the mornings. A night of surface cooling gives a very
low-level temperature inversion near the ground that could lead to a
temporary improvement in Tropo.
In the second half of the week it is likely that low pressure
tracking westwards across southern Britain will bring the prospect of
snowfall and perhaps icing on antenna wires and beam elements. It is
always worth checking the tensions are good and shake off any ice
build-up in this sort of weather.
We are still a month or so away from the return of Northern
hemisphere Sporadic-E, so the best opportunity for DX on the lower
bands still lies in early morning random meteor scatter contacts.
The Moon is at maximum declination today so, combined with low path
losses with perigee this Tuesday, it is a good week for EME.
And that's all from the propagation team this week.
And that's the end of the main news for this week prepared by the
Radio Society of Great Britain. Items for inclusion in subsequent
bulletins can be emailed to gb2rs<at>rsgb.org.uk to arrive by
10:00 on the Thursday before transmission.
Our thanks to Andy G4TNU for providing this RSGB feed.
