GB2RS Main News for Sunday the 27th of April 2025
The news headlines:
* RSGB delegates attend special IARU Region 1 Interim Meeting
in Paris
* Join the RSGB in celebrating World Morse Day
* Be part of the RSGB's team at the Youngsters on the Air
summer camp
The RSGB is participating in the International Amateur Radio Union
Region 1 Interim Meeting in Paris this weekend. The event is of
particular historical significance as it coincides with the centenary
of the founding of the IARU in 1925, as well as the 75th anniversary
of the establishment of IARU Region 1 in 1950. The French host
society, REF, is also marking its 100th anniversary. This year's
meeting in Paris reflects a broader scope than in previous years and,
for the first time, includes ‘Youth Matters' on the agenda. It also
covers the usual focus areas of HF, VHF, UHF and Microwave, as well
as Electromagnetic Compatibility. The RSGB has been a key contributor
to the meeting, submitting papers that include future options for the
23cm band and the harmonisation and protection of HF bands. Three
delegates from the RSGB are attending the meeting in person,
including the newly appointed RSGB President Bob Beebe, GU4YOX. There
will be eight other RSGB representatives attending remotely. The
meeting serves as both a celebration of amateur radio's rich heritage
and a forward-looking forum to address the challenges and
opportunities facing the global amateur radio community. You can view
meeting documents at conf.iaru-r1.org In celebration of the
centenary of the IARU the RSGB has created a web page to share
information about its part in the celebrations. This includes a link
to an RSGB archive video from the IARU meeting in Paris in 1950, as
well as the RSGB's July 1925 T & R Bulletin that contains an
announcement detailing the formation of the IARU. Go to
rsgb.org/iaru-centenary for further details.
Today, Sunday the 27th of April is World Morse Day. The day honours
the birthday of the inventor of Morse code, Samuel Morse, who was
born on this day in 1791. To celebrate the occasion, the RSGB has
released a video with a question in Morse code for you to answer.
Once you have used your Morse skills to decipher the question, get
involved by leaving your answer in the comments section under the
post. You can view the video on the RSGB YouTube channel via
youtube.com/theRSGB or search for <at>theRSGB on Facebook or X.
The deadline to apply to be the Team Leader for this year's
Youngsters On The Air Summer Camp is Friday the 2nd of May. This
year's camp takes place between the 18th and 25th of August near
Paris and is a chance of a lifetime for young RSGB members to
represent their country and their national society. If you are an
RSGB member, aged between 21 and 30, and are able to motivate a team
of young people, then the RSGB would love to hear from you. Download
an application form and apply for this exciting opportunity by going
to rsgb.org/yota-camp Applications to be a Team Member will remain
open until the 16th of May.
The RSGB Exams Quality Manager would like to remind everyone that
clubs can still run exams if they are a Registered Exam Centre. Exams
will be conducted online unless a candidate has a special requirement
for a paper exam. The introduction of remote invigilation to allow
people to take an amateur radio licence exam in their home does not
affect this. If clubs have any queries about delivering exams, they
should contact the RSGB Examinations Quality Manager, Dave Wilson,
M0OBW via eqam<at>rsgb.org.uk If anyone has special requirements for
an exam, they should contact the RSGB exams team via
exams<at>rsgb.org.uk
As part of the IARU centenary celebrations, the RSGB has been
activating callsign GB0IARU throughout April. On Wednesday the 30th
of April, the RSGB President Bob Beebe, GU4YOX will be activating
GB0IARU from 2pm on 40m SSB, and then from 5pm on 80m SSB.
Frequencies will be spotted on the day, and times may vary to suit

Now the radio propagation report, compiled by G0KYA, G3YLA and G4BAO
on Thursday the 24th of April 2025
We had yet another week of unsettled geomagnetic conditions. The Kp
index peaked at 5.33 on the 21st of April as the solar wind speed hit
just above 600 kilometres per second, and active geomagnetic
conditions were observed.
This was caused by a massive coronal hole on the Sun's surface, which
measures nearly 700,000km in length. At the time of writing, part of
it is still Earth-facing, but the Bz or interplanetary magnetic field
is facing North, so its negative effects are not being felt.
The Kp index was down to 3.67 on the morning of Thursday the 24th of
April, but it wouldn't take much for the Bz to swing southwards and
for the Kp index to rise again.
Meanwhile, the solar flux index has risen from a recent low of 148 up
to 168. This has meant MUFs over a 3,000km path have reached 25MHz at
times, but have usually been slightly lower. If the Kp index can stay
low there is a good chance of higher MUFs being attainable, but we
have probably seen the best of 10m propagation until the autumn.
Much of the recent DX has been worked on slightly lower frequencies,
such as VP2VI British Virgin Islands on 40 and 20m, C5R The Gambia on
20 and 12m, and HD8G Galapagos Islands on 20, 17, and 12m. There is
still the chance of DX on 10m, but it may be fleeting.
Next week, NOAA predicts that the solar flux index will stay high,
perhaps reaching 170 to 175. We may get a slight respite from
unsettled geomagnetic conditions from the 26th to the 30th of April
when the Kp index is forecast to be around two to three. However,
unsettled geomagnetic conditions are forecast for the beginning of
next month, with Kp indices of five or six on the 1st and 2nd of May.
And now the VHF and up propagation news from G3YLA and G4BAO
Next week high pressure should dominate, meaning a chance of Tropo
for much of the time that will probably favour paths to the east, to
Scandinavia or northern Europe.
Rain scatter won't have featured much other than over northwest
Britain in recent days, and meteor scatter is reducing back to random
activity which tends to be better in the early hours before dawn.
The solar conditions have continued to keep the Kp index up and there
was a fine auroral opening last week on the 16th of April, so for
more aurora, it's still worth checking for when Kp values nudge above
five.
As the end of April moves into May we can start to give serious
thought to the coming Sporadic-E season. Hesitant beginnings often
show up on 10m and 6m and, as usual, the digital modes will be best
for any weak events. CW and SSB are just possible in the stronger
openings, especially on 10m.
The background rule is that there are usually two preferred activity
periods, one in the morning and a second in late afternoon and early
evening. However, at the start of the season, there can be a lot of
spread in the timings.
EME path losses are at their lowest with perigee today, Sunday the
27th, and Moon declination is positive and rising. Moon windows will
lengthen along with peak elevation, and 144MHz sky noise starts the
week low but increases to moderate as the week progresses. From late
Sunday to early Monday, the Sun and Moon are close.
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 radcom<at>rsgb.org.uk to arrive by
10:00 on the Thursday before transmission.
