GB2RS Main News for Sunday 7 August 2011
The news headlines:
* Portugal gets amended 6m band
* Dutch amateurs get new frequencies
* Pic-A-Stars get together
The National Communications Authority of Portugal has accepted a
proposal to amend the upper frequency limit on the 6m band, effective
from 4 April 2012. That coincides with the date of the complete
switch-off of the analogue TV broadcasting transmissions and the
changeover to digital terrestrial television. The new limits of the
band allocation for Portugal will be from 50 to 52MHz once analogue
television disappears from that spectrum.
Amateurs in the Netherlands now have access to bands at 500kHz and
70MHz. This after the Dutch Minister of Economic Affairs, Agriculture
& Innovation issued a Decree on 6 July changing the National
Frequency Plan. The revised band plan shows an amateur service bands
at 501 to 505kHz that will remain available until 1 January 2014. It
also shows a new allocation from 70.0 to 70.5MHz that has no time
limit.
Pic-A-Star is an SDR radio designed by Peter Rhodes, G3XJP, which was
serialised in RadCom. It also appears in the RSGB Radio Communication
Handbook. Milton Keynes ARS and Milton Keynes Museum are inviting all
constructors of Pic-A-Stars to a one-day get together. This will be
on Sunday 11 September from 11am to 4pm at the Milton Keynes Museum.
Constructors of the Pic-A-star project are invited to bring their
radios for a gathering and exchange of ideas. Star add-on circuits
are also welcome. Entry will be free, but it would be nice to leave a
small donation to the Museum. Constructors of other equipment
designed by Peter are also welcome but the emphasis will be on the
Pic-A-Star project. There will be test equipment and an antenna
available on the day. Further details and directions are available
online at
www.radio-kits.co.uk/pic_a_star/event.htm.
The Limerick 2m repeater on 145.725MHz is now on the air again after
being shut down due to vandalism at the repeater site. Limerick Radio
Club is grateful for the many generous donations received, which have
gone towards installation of a new security door. A new run of
hardline coax has also been installed from the hut to the mast.
On Friday 12 August, Itchen Valley Amateur Radio Club will be holding
a fun ARDF event and barbecue at the IBM Sports Clubhouse, Hursley.
The ARDF event will take place from 6.30pm onwards with the barbecue
starting at 7.30pm. All equipment will be supplied and, as this is a
fun and social event, spouses and children will be welcome to
participate. There is no requirement to hold an amateur radio
licence. Full details are available on the club website,
www.ivarc.org.uk. Itchen Valley club members should note that this is
a change of venue and there will be no meeting at the club house in
Brickfield Lane.
Advance notice now. To celebrate their 80th anniversary, Midland
Amateur Radio Society will be holding an open day at the club from

GB2MYA. Further information is on QRZ.com.
And now the HF DX news compiled from 425 DX News and other sources
VA3ITA will be on the air from 8 to 11 August, signing as /portable
ZB2 in a VHF-only operation from Gibraltar. Operations will be on 6
and 2 metres using a mix of digital, SSB and CW from the east side of
the Rock, facing the Mediterranean Sea. Please check his QRZ.com page
for the latest news and e-mail him directly to schedule a contact.
QSL direct via home callsign either direct or via the bureau.
KF8UN will be in Peru until 16 August. He will be active stroke OA4
and says that he plans to work 20 metres with particular emphasis all
day on 8 August. At other times he will be operating holiday style.
QSL via his home callsign.

IOTA reference EU-170, until 10 August. QSL via his home callsign.
TM5SM will be on the air from the Saint Marcouf Islands, which is

Now the contest news
The 432MHz Low Power Contest takes place today, 7 August, from 0800
to 1200UTC. Using all modes the exchange is signal report, serial
number, locator and the first two letters of the postcode.
Also today, 7 August, is the 2nd RoPoCo event. It's a 90-minute
Sunday morning event from 0700 to 0830UTC in which you really need to
be on your toes to do well, because the rolling exchange of postcodes
is a real challenge. This is the CW leg, the SSB leg having taken
place in April.
Tuesday 9 August sees the 432MHZ UK Activity Contest taking place
between 1900 and 2130UTC. Using all modes on the 70cm band, the
exchange is signal report, serial number and locator.
The new series of 80m Club Sprints starts in August and lasts four
months. It begins with CW on the 10th from 1900 to 2030UTC. The
Sprint contest exchange is both callsigns, a serial number and your
name (or nickname in the case of some people). After soliciting a QSO
you must QSY a minimum of 2kHz before you can call another station or
solicit another QSO. Most of the time this will result in you having
two QSOs on a frequency before you have to QSY, the first when you
call someone and the second when you have taken over the frequency
and called QRZ or CQ.
On 14 August the 70MHz Cumulative takes place between 1400 and
1600UTC. Using all modes the exchange is signal report, serial number
and locator.
For the entire 48 hours of 14-15 August, European stations work
non-Europeans only in the Worked All Europe DX CW Contest. Using CW
on the 3.5 to 28MHz bands the exchange is signal report and serial
number.
And now the solar factual data for the period from the 25th to the
31st of July, compiled by Neil Clarke, G0CAS on the 1st of August.
Right at the start of the period on the 25th a large sunspot group
rotated into view. This was followed by another on the 26th and yet
another on the 28th. All these three groups were complex enough to
produce large solar flares, and this is just what they did. Solar
activity increased to high on the 30th when a M9 class solar flare
occurred, and moderate on the 27th when a M1 flare took place. The
remaining days' activity was low with numerous C class solar flares
of varying strength taking place. Several sudden ionospheric
disturbances accompanied some of the larger flares. Solar flux levels
increased steadily from 87 units on the 25th to 119 by the 31st. The
average was 104 units. The 90 day solar flux average on the 31st was
95 units, that's the same level as last week. X-ray flux levels
increased from B1.7 units on the 25th to B5 units by the 29th and the
average was B3.7. Geomagnetic activity was slightly unsettled on the
25th due to a small coronal hole when the Ap index was 12 units. The
following few days saw quiet conditions till the next coronal hole
disturbance arrived around midday on the 30th. The most disturbed day
was the 30th with an Ap index of 16 units. The average was Ap 8
units. Solar wind data from the ACE spacecraft saw solar wind speeds
at 650 kilometres per second on the 25th but then to 280 by the 29th.
Speeds then increased to end the period at 700 kilometres per second.
Particle densities were low every day. Bz varied between minus 12 and
plus 10 nanoTeslas on the most disturbed day and between minus 3 and
plus 2 nanoTeslas when activity was quiet.
And now the solar forecast. This week the quiet side of the Sun is
expected to be rotating into view. Solar activity is expected to be
very low to low. Solar flux levels should be around the 90 mark most
days. Geomagnetic activity is expected to be at quiet levels for the
next few days but on Thursday a recurring coronal hole is expected.
On its last rotation the hole was small and on the most disturbed day
the Ap index only reached 13 units. MUFs during daylight hours at
equal latitudes should be around 22MHz for the south and 19MHz for
the north. Darkness hour lows should be about 12MHz. Paths this week
to Middle East should have a maximum usable frequency with a 50 per
cent success rate of around 21MHz. The optimum working frequency with
a 90 per cent success rate will be about 16MHz. The best time to try
this path will be between 1100 and 1700 hours. Sporadic-E should take
place on most days; there is a chance that the Middle East could be
worked via multi-hop Es.
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 Tuesday before transmission.
