GB2RS Main News for Sunday the 26th of June 2022
The news headlines:
* RSGB joins IARU Region 1 meeting
* GB70D on air from the Isle of Man
* Tonight<at>8 on Monday
RSGB volunteers and staff contributed to the IARU Region 1 Interim
meeting at Friedrichshafen on Thursday the 23rd of June. The meeting
covered topics across HF, VHF and UHF as well as Microwave and EMC
matters. This included the latest state of preparations for WRC-23
where agenda item 9.1B on the protection of satellite navigation
systems, such as Galileo in the 23cm band, was of prime interest.
Slides showing the current state and this potentially significant
threat to the radio amateur and amateur satellite services have been
published on the RSGB special focus page at rsgb.org/wrc-23. The
IARU, supported by the RSGB, continues to work hard to reduce any
impact.
The Queen's Platinum Jubilee station GB70D is based on the Isle of
Man. On Tuesday the 28th, it will be based in the grounds of
Government House. It is hoped that the Lieutenant Governor of the
Isle of Man and Lady Philippa will participate for several periods
during the day. The station plans to operate on 2m, as well as SSB
and CW on most bands from 40m up. Operations start around 9.30am.
Tonight <at>8 will take place on Monday, the 4th of July. This is the
final lecture before the summer break. Peter Duffett-Smith, G3XJE
will be looking at Radio waves and antennas…and all that. His
presentation covers a range of antenna-related information so there
should be something for everyone. Tonight<at>8 webinars are
live-streamed on the RSGB's YouTube channel, YouTube.com/thersgb.
The 98-year-old 200kW Alexanderson alternator, callsign SAQ, will not
be able to air on Alexanderson Day, Sunday the 3rd of July. This is
due to difficulties in obtaining components in the ongoing
maintenance work. The Alexander Association welcomes visitors to the
museum on the 3rd from 10am to 4pm. Together with the World Heritage
Grimeton Radio Station they will offer many activities for the whole
family during the day. There will be two transmitter startups with
SAQ, but without any transmission over the antenna.
National society in Iceland, IRA, reports on the renewal of special
authorisation to use 50MHz. Icelandic licensees have been granted
increased power licenses in the 50-50.5MHz frequency range until the
31st of September. Full licensees are allowed to use up to 1kW and
Novice licensees up to 100W.
The 2022 AMSAT-UK International Space Colloquium will be held as part
of the RSGB Convention on the 8th and 9th of October at Kents Hill
Park Conference Centre in Milton Keynes. The weekend event attracts
an international audience that ranges from those involved in building
and operating amateur radio satellites to beginners who wish to find
out more about this fascinating branch of the hobby. Find out more at
amsat-uk.org or rsgb.org/convention.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO
on Friday the 24th of June 2022.
As predicted, the solar flux index fell back this week, but it didn't
fall as low as experts predicted. On Thursday, it stood at 129, but
with three sunspot groups about to rotate off the visible surface, it
looks like it may now fall lower.
We are now well and truly into the summer season for HF propagation,
which can be characterised as providing lower maximum usable
frequencies during the day, but higher MUFs at night. Sporadic-E
remains the most common mode of propagation on the higher bands, with
F2-layer MUFs over 3,000 kilometres generally not exceeding 21MHz for
most of the day. But more on Sporadic E in the VHF segment of this
report.
The good news is that 20 metres stays open later, often providing
paths over 3,000km up until midnight. The higher bands, that is 17
metres, 15 metres and perhaps 12 metres, may generally provide good
paths to South America in the evenings, with 20-metre paths being the
last to close.
But we're afraid we may have to wait until September to see good
reliable paths into North America on HF once again.
Next week, NOAA predicts that the SFI will remain around the 100
mark, so we may expect lower MUFs again, apart from Es openings.
Geomagnetic conditions should generally be quiet with a maximum Kp
index of two once we get over any disturbance this weekend due to a
high-speed solar wind stream.
And now the VHF and up propagation news.
The recent very warm and humid weather has produced some occasional
Tropo with the British Isles being on the edge of high pressure,
mainly over the near continent. This may still happen occasionally in
the coming week, but the fundamental characteristic for next week is
low pressure and unsettled weather over the UK. This will produce
some rain, with thunderstorms a possibility, and rain scatter will
crop up as a useful mode on the upper GHz bands at times.
The many online weather radar displays will allow you to keep a track
of storms as they develop. When low pressure is centred over the
country the showers may be longer-lasting and not decay overnight, so
this period looks more promising than the usual mainly daytime shower
distribution.
The Sporadic-E season is in full swing, but in a rather restrained
way since openings have been fairly limited and often fleeting. The
presence of jet streams on the weather charts is a good indicator of
regions where Es is more likely and the coming week offers a good
variety of options, so if Sporadic-E is hard to find then perhaps
other parameters may not be optimal; for example, the meteor input is
a crucial component in the development of Es. Check the daily
conditions for jet streams on the Propquest.co.uk EPI maps and Es
blog.
The June meteor showers, mentioned last week, continue into early
July so keep checking meteor scatter conditions between the Es.
With the Moon at maximum declination on Wednesday, Moon windows are
long this week. Today, Sunday the 26th of June, the Moon is at
apogee, or its furthest point from Earth, so path losses are at their
highest, and for around four hours after UK Moonrise on Wednesday the
Sun is close to the Moon so noise will be high at that time.
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.
