The news headlines
" Space scientist and Sky at Night Presenter at the RSGB Convention
" 5MHz logging program amended
" European Parliament report published
It has been announced that space scientist and Sky at Night presenter,
Dr Lucie Green will be lecturing at the RSGB Convention later this year.
As part of the VHF & Up stream, Dr Green will be talking on her work in
understanding how immense magnetic fields in the Sun's atmosphere evolve
to the point where they erupt as a coronal mass ejection. Last year, Dr
Lucie Green was the recipient of the 2009 Royal Society Kohn Award for
Excellence in Engaging the Public with Science. You can book your
tickets for the RSGB Convention, which will take place from 8 to 10
October near Milton Keynes, via www.rsgbevents.org.
Following the extension of UK amateur's experimental access to 5MHz
channels, Alan, G0TLK has kindly written a software 'patch' to allow his
5MHz logging program, 5MHzLog, to work until 30 June 2015. It will
otherwise stop working at the end of June 2010. The patch can be
downloaded from his website, where you will also find installation
instructions. This page is linked from the 5MHz Station Logging web page
at www.rsgb.org/spectrumforum/hf/log.php.
The European Parliament published the Second Progress Report On The
Operation Of Directive 1999/5/EC on radio equipment and
telecommunications terminal equipment and the mutual recognition of
their conformity, which might affect amateur radio in the future. Thilo,
DL9KCE asks that amateurs read this document and possibly intervene
through your national MEPs if you think it necessary. You can see the
report via the IARU Region 1 website, www.iaru-r1.org.
The open day at Hull & District Amateur Radio Club scheduled for 17 July
has been cancelled and put back a couple of months. Instead the club

County Dublin in Southern Ireland is open every day from 11am until 4pm.
The museum is run on a voluntary basis by Pat Herbert, an enthusiastic
collector of radio memorabilia for the last 50 years. The Howth Martello
Radio Group operates an amateur radio station, EI0MAR, most weekends.
Amateurs are more than welcome to visit and operate the station by prior
arrangement. Contact details and more information are on the website,
www.ei0mar.org.
The UK regulator, Ofcom, has announced its decision on 24GHz automotive
Short Range Radar (SRR) and thanked the RSGB for their response on the
subject. You can read the full statement by putting 24GHZ into the
search box on the Ofcom website www.ofcom.org.uk.

And now the HF DX news compiled from 425 DX News and other sources.
From 19 June to 15 August YO/M0GQU will be on air as part of an 'off
road' expedition to Transylvania with the 4x4 Vampire Tour. This is an
annual event that involves 900km of forest road, meadows and mountain
peaks. The idea is to activate a mobile work station YO/M0GQU/M and base
YO/M0GQU. During the day the station will be heard primarily on 80m and
20m. If the propagation conditions allow, you may also find them on 10m
and 6m. All information about this event can be found at
www.transylvania.4x4zone.co.uk.

frequencies. QSL via his home callsign, direct only.
Dennis Motschenbacher, K7BV will be active as 5J0BV from San Andreas
Providencia from 9 to 20 June. While not as rare in the USA, there still
appears to be a large demand for this location world-wide even after
Dennis's two previous operations devoted to 6 meters. More on this
operation including QSL routing is online at www.tinyurl.com/2unguet.
Franco, IL7/IK4YCQ, will be on the air from San Domino Island and

Now the contest news
The RSGB UHF UK Affiliated Clubs results are now available on the RSGB
Contest Committee website. There were 118 stations active for the
contest and there was a record turnout on 23cm with 43 entries. See the
results at www.rsgbcc.org/vhf/results/10/uhfukac.html.
Today, 6 June, the Practical Wireless magazine 4m low power contest
takes place between 1200 and 1700UTC. The maximum power allowed is 10
watts. Using all modes the exchange is signal report, serial number and
locator.
The data leg of the 80m Club Championships take place on 7 June from
1900 to 2030UTC. The exchange is signal report and serial number.
The 432MHz UK Activity Contest takes place between 1900 and 2030OUT on 8
June. The exchange is signal report, serial number and locator.
On Saturday 12 June, the BARTG 75 Baud Sprint is a new contest taking
place between 2000 and 2359UTC. This is a try-out event, to test if
there is sufficient support and interest to make it worthwhile for BARTG
to add it to their calendar annually. There are only two classes of
entry, each for single operators. The bands are 14 and 28MHz and the
exchange is serial number only.
Sunday 13 June is another busy day for contest. The WAB 6m phone contest
takes place between 0900 and 1500UTC. The exchange is signal report,
serial number and WAB square. Please note that this is not a 'points per
km' event. Multipliers are WAB squares and DXCC countries. On the same
day there's the PW 2m QRP contest from 0900 to 1600UTC. The power limit
is 3 watts and multipliers are locator squares. The exchange is signal
report, serial number and locator. Finally the second 144MHz backpackers
contest takes place between 1100 and 1500UTC. The exchange is signal
report, serial number and locator.
Now the solar factual data for the period from the 24th to the 30th of
May, compiled by Neil Clarke, G0CAS on the 31st of May.
Sunspots were visible every day and from the 29th three groups were
visible. All were small and magnetically simple and no group produced
any solar flares worthy of any note. Solar activity was very low. Solar
flux levels showed a slight increase of only two units during the
period. The average was 73 units. The 90 day solar flux average on the
30th remained the same level as last week at 78 units. X-ray flux levels
varied little and averaged A2.9 units. Geomagnetic activity started at
quiet levels with an Ap index of only 2 units on the 24th. Activity
started to increase late on the 28th which was too late to increase the
Ap index to more that 10 units for that day. With a prolonged period of
negative Bz down to minus 14 nanoTeslas on the 29th lasting almost 20
hours the Ap on the 29th was 33 units. This disturbance was in response
to a coronal mass ejection that took place on the 23rd and 24th. The
average was Ap 11 units. Solar wind data from the ACE spacecraft saw
solar wind speeds increase from 280 kilometres per second on the 25th to
530 by the end of the period. Particle densities were low except for the
brief increases to 11 and 14 particles per cubic centimetre on the 28th
and the 30th respectively. Bz varied between minus 2 and plus 3
nanoTeslas on the quietest day and between minus 14 and plus 11
nanoTeslas during the disturbance.
HF MUFs were depressed by several megahertz on the 29th, with
high-latitude paths particularly degraded. VHF aurora was reported at
50, 70 and 144MHz across the whole of northern Europe, including most of
the UK. Sporadic-E took place just about every day with openings up to
70MHz from the UK and 144MHz in some parts of Europe.
And now the solar forecast. Without the emergence of any large sunspot
groups solar activity is expected to be very low. Some days the solar
disc could be spotless this week. Solar flux levels should be in the low
70's for most of the week. Geomagnetic activity is expected to be at
quiet levels everyday. MUFs during daylight hours at equal latitudes
should be around 19MHz for the south and 16MHz for the north. Darkness
hour lows should be about 11MHz. Paths this week to the Middle East via
the F layer should have a maximum usable frequency with a 50 per cent
success rate of around 20MHz. The optimum working frequency with a 90
per cent success rate will be about 15MHz. With the peak of the
sporadic-E season almost upon us, openings to this area should take
place via 'double-hop' sporadic-E on some days. Single-hop openings will
also take place more readily on most days with openings up to 144MHz
during any large scale openings.
And that's all for this week from the propagation team.
