The Reunion of the Radio Security Service ex-members on Sunday 17
April in the Mansion at Bletchley Park will include an illustrated
lecture on how radio amateurs helped to win the war. More than a
thousand amateur radio volunteers listened on the short wave bands,
in secret in their own homes, for illicit signals in the UK. What
they uncovered were the transmitters of the German Secret Service
operating all over Europe and beyond. Besides penetrating the most
secret aspects of the service they also learnt about spies sent here.
Some of them were 'turned' to work for us under the supervision of
radio amateurs, notably Ronnie Reed, G2RX. More can be found at
http://secretlisteners.org.
On 3 April a new distance record set for optical communication by a
group of radio amateurs from North-East England. The distance worked
was just a few metres short of 90km. Signals were exchanged on FM and
SSB at remarkable strengths. The contact was made from Race Head in
County Durham, which is locator IO94VS to Danby Moor near Whitby,
which is locator IO84NK. The team at Race Head included two stations,
Stuart, G8CYW running the transverter and LED transceiver of his
design featured in recent articles in RadCom, and Brian, G8KPD also
running his version of the designs, plus separate receive and
transmit heads. The station on Danby Moor was operated by Rob, M0DTS
using his version of the transverter featured in RadCom.

callsign, 4W6A, from ARCOM, the licensing authority in Dili. The team
is very grateful to ARCOM for issuing this special one-letter
callsign for use on the DXpedition. The DXpedition has a website at
www.4W6A.com, which includes profiles of the team members,
propagation predictions and lots of information about Timor-Leste and
Atauro Island, the location of the DXpedition.
A major IOTA expedition that incorporates several different IOTA
references in Papua New Guinea has just started and the team are
currently Nuguria Islands, IOTA reference OC-257, where the call

Now the contest news
The 432MHz UK Activity Contest is taking place on Tuesday 12 April
from 1900 to 2130UTC. Using all modes the exchange is signal report,
serial number and locator.
On Wednesday 13 April, the 80m Club Championships SSB leg is taking
place between 1900 and 2030UTC. The exchange is signal report and
serial number.
On Saturday 16 April the Spring EU Sprint SSB contest takes place
between 1600 and 2000UTC on the 3.5 to 14MHz bands. It's a 4-hour
event with a rigid exchange structure of both callsigns, a serial
number and your name (or nickname). You'll have to engage in some
band hopping, to make the most of changing conditions.
And now the solar factual data for the period from the 28th of March
to the 3rd of April, compiled by Neil Clarke, G0CAS on the 4th of
April.
To start this week an update on the latest smoothed monthly sunspot
numbers which are for June, July and August 2010 and are 16.4, 16.8
and 17.4 respectively.
The two large complex sunspot groups that were visible on the solar
disc for most of the week failed to produce any large solar flares.
They could only produce isolated small C class solar flares everyday
except for the 2nd. On occasions, small sudden ionospheric
disturbances and coronal mass ejections occurred with these flares
but their effect on propagation was minimal. Some days they were up
to six groups visible but many were very small. Solar flux levels
declined from 119 units on the 28th to 108 by the 2nd. The average
was 114 units. The 90 day solar flux average on the 3rd was 99 units.
That's three units up on last week. X-ray flux levels varied little
day to day and averaged B3 units. Geomagnetic activity was quiet
every day until the 1st when a recurring coronal hole disturbance
arrived. This carried on through to the 3rd. The most disturbed day
was the 2nd with an Ap index of 20 units. The average was Ap 9 units.
Solar wind data from the ACE spacecraft saw solar wind speeds
increase from 300 kilometres per second to 710 by the 2nd. Particle
densities were low except for an increase to 40 particles per cubic
centimetre during the evening of the 29th. Bz on the quiet days
varied between minus and plus 4 nanoTeslas and between minus and plus
10 nanoTeslas during the disturbance. Interestingly, on the 30th the
Bz remained positive for the complete day and varied between plus 5
and plus 13 nanoTeslas.
And now the solar forecast. This week solar activity is expected to
be at low levels, however there is a chance that activity could
increase on some days. Solar flux levels are expected to decline and
be in the 90s for most of the week. Geomagnetic activity is expected
to be quiet everyday. MUFs during daylight hours at equal latitudes
should be about 25MHz for the south and 22MHz for the north. Darkness
hour lows are expected to be about 10MHz. Paths this week to South
Africa should have a maximum usable frequency with a 50 per cent
success rate of around 31MHz. The optimum working frequency with a 90
per cent success rate will be about 24MHz. The best time to try this
path will be between 1100 and 1600 hours UTC.
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.
