GB2RS Main News for Sunday 12th May 2013
The news headlines:
* 2.4GHz band call for input
* New EME record on 24GHz
* Moonbounce planned for G100RSGB
Ofcom has published a call for inputs relating to spectrum use by
licence exempt devices in the 2,400MHz band. This band is close to
radio spectrum in the 2,300MHz band, which the Ministry of Defence
plans to release for new civil uses. The MoD has therefore
commissioned work to audit licence exempt uses in the 2,400MHz band,
in particular to identify the full range of possible uses of this
spectrum. The call for inputs introduces two audit reports that
explore licence exempt use in the 2,400MHz band. It also invites
stakeholders to identify any other uses that may need to be
considered to understand any technical coexistence. In addition to
licence exempt use, the 2.4GHz band is also a secondary allocation
for the amateur services, including ATV repeater outputs and
satellite downlinks. The Ofcom consultation is at
http://stakeholders.ofcom.org.uk/consultations/2400-mhz.
Rex Moncur, VK7MO, has completed a Earth Moon Earth QSO with the
OK1KIR EME Team in the Czech Republic at a distance of some 10,180
miles, to claim the new world EME record on 24GHz. VK7MO used a 1.14m
dish and 10 watts and OK1KIR used a 4.5m dish and 22 watts.
G100RSGB, the special event callsign celebrating the RSGB Centenary
will be operated by Fort Purbrook Radio Club today, 12 May, using the
40, 20, 4 and 2m bands as well as 70cm. On Monday, Horsham ARC will
put the callsign on the air from Ifield, running 10 to 160m as well
as 2m. On Tuesday, the Isle of Wight RC will operate on the HF bands
plus 6m, 2m and 70cm from Ryde. Then on 16th and 17th, the callsign
moves to Corsham with the North Wiltshire DX Group, running a mostly
CW station on 10 to 80m. The UK Microwave Group will put the station
on the air in Andover running CW, SSB and digital including EME on
the 18th and 19th. They will mainly use the 3cm band but some
activity will be on the 23cm to 12mm bands. Details of how to get
your QSL card are on the website, www.rsgb.org.uk under the Operating
drop down menu, clicking on Centenary Station.
According to the IARU Region 1 Monitoring System newsletter, Spanish
GPS buoys are a new threat to the 28MHz band. You can find their
bursts between 28 and 28.5MHz transmitting in F1B with 51 baud and
about 300Hz shift. They were observed and measured by DK2OM and
HB9CET and found to be in the Atlantic Ocean, west of Portugal. The
Portuguese Monitoring System informed the Portuguese authorities.
There is still time to apply for funding from the Radio
Communications Foundation for projects to promote the benefits of
radio to the general public. The Foundation meets on 15 May to
consider small projects that would benefit from funding. Send
details, by e-mail, to marilyn.slade<at>rsgb.org.uk. All decisions on
whether to provide financial support are made by the Trustees and
there is no certainty that any project proposed will receive funding.

And now the solar factual data for the period from Friday the 3rd to
Thursday the 9th of May, compiled by Neil Clarke, G0CAS, on Friday
the 10th of May.
Numerous sunspot regions were visible every day. A few were large
enough to produce solar flares every day. Solar activity increased to
high when a M5 class solar flare took place on the 3rd and a M1 class
flare on the 5th when activity was at moderate levels. The remaining
days activity was at low levels, with C class solar flares taking
place. Solar flux levels declined from 148 units on the 3rd to 127 by
the 8th. The average was 135 units. The 90 day solar flux average on
the 9th was 117 units, that's two units up on last week. X-ray flux
levels declined from B6.5 units on the 3rd to B4.3 by the 8th. The
average was B5.6 units. Geomagnetic activity was quiet every day
except for the 7th, when activity increased slightly to unsettled
levels due to a small coronal hole. The Ap index for the 7th was 12
units. The average was Ap 8 units. Solar wind data from the ACE
spacecraft saw solar wind speeds increase from 330 kilometres per
second on the 4th to 600 by the morning of the 6th. Speeds then
gradually declined to 420 kilometres per second by the end of the
period. Particle densities were low except for a brief increase to 45
particles per cubic centimetre on the 6th. Bz varied between minus 7
and plus 11 nanoTeslas on the 6th during the weak disturbance and
between minus 4 and plus 1 nanoTeslas on the quietest day.
And finally the solar forecast for the coming week. This week solar
activity is expected to be low, however, there is a reasonable chance
of activity increasing on the occasional day. Solar flux levels are
expected to be around the 120s but could increase towards next
weekend. Geomagnetic activity is expected to be quiet every day.
However, if a coronal mass ejection heads our way then activity would
increase. MUFs during daylight hours at equal latitudes should be
around 23MHz for the south and 20MHz for the north. Darkness hour
lows should be about 12MHz. Paths this week to India should have a
maximum usable frequency with a 50 per cent success rate of around
22MHz. The optimum working frequency with a 90 per cent success rate
will be about 17MHz. The best time to try this path will be between
1100 and 1600 hours UTC. Sporadic-E is expected to take place on some
days up to 70MHz. In any intense openings propagation is possible on
144MHz.
And that's all for this week from the propagation team.
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.
