Sunday the 5^th of May 2024

 

The news headlines:

• RSGB insurance update
• RSGB Legacy Committee Chair appointed
• SOS Radio Week is under way

 

RSGB club insurance, and beacon and repeater insurance, have now been renewed for the year to April 2025. Club insurance certificates can be downloaded from the RSGB website. You will need to log in to obtain your certificate. Beacon and repeater insurance certificates are available for an admin fee of £15 from the RSGB shop. Please allow a couple of days after renewal for your certificate to be dispatched.

The RSGB Board is pleased to announce it has approved the appointment of Richard Horton, G4AOJ to the role of Legacy Committee Chair. The RSGB Legacy Fund, thanks to the generosity of donors, has significant financial resources available to encourage and develop amateur radio. The Legacy Committee, which is a sub-Committee of the RSGB Board, considers proposals for grants that can be awarded to projects from the RSGB Legacy Fund. The criteria and application form are available on the RSGB website at rsgb.org/legacy  If you have an interesting idea and would like to submit it for funding, you can contact the new Legacy Chair via legacy.chair@rsgb.org.uk

SOS Radio Week is underway. It is an annual event that takes place throughout the month of May to celebrate the work of the volunteers from the Royal National Lifeboat Institution, Independent Lifeboats and National Coastwatch Stations around the British Isles. Between them, members of these organisations save many lives who are in danger along and around the thousands of miles of coastline and further out to sea. This year is the 200^th anniversary of the founding of the RNLI, and SOS Radio Week is being co-branded SOS Radio Week 200 for those operators who are supporting the RNLI during the event. Participants can operate from home, a public location, or a lifeboat or Coastwatch station, with the appropriate authorisation from the station manager. A commemorative certificate is available to all official stations that record their contacts on the website together with awards for the top individual and club, or group, stations on each band from 160m to 70cm. To read more about the event visit sosradioweek.org.uk

The next in the series of the popular 145 Alive events, to promote the use of 145MHz FM, is coming up on Saturday the 11^th of May, from 1pm to 3pm. The event and the supporting Facebook Group was started by Tim, G5TM and from the start of 2024 has been organised by Mark, M0XIC and John, M0XJA. The last successful event took place in January this year, when over 30 nets operated simultaneously across England, Scotland, Wales and Northern and Southern Ireland. Over 900 QSOs took place, with many amateurs operating portable, mobile or from their club or home QTH. If you would like to take part, and find out more about the event and 145 Alive in general, then join the 145 Alive Facebook Group.

Next weekend, the 11^th and 12^th, lots of amateur radio stations will be taking to the air as part of Mills on the Air Weekend 2024. The event takes place across the UK every May with more than 300 windmills and watermills usually taking part. For more information, to register, and to view a list of registered stations, visit ddars.net/mills.html

Advance notice now that International Museums Weekend will be taking place on the third and fourth weekends in June. This year, those weekends are the 15^th and 16^th, and the 22^nd and 23^rd of June. Special event stations will be operating from a wide variety of museums from many different countries.

Now the radio propagation report, compiled by G0KYA, G3YLA, and G4BAO on Thursday the 2^nd of May 2024

What a strange week we had. With the solar flux index in the 167 range, falling to 130, conditions should have been reasonable. But the Kp index hit 4, and even 5.33, on the evening of Friday the 26^th of April, which meant propagation on Saturday the 27^th was truly dire.

Stations taking part in International Marconi Day on the 27^th found the 40m band only open to long skip in the morning. This was due to the critical frequency being below 5MHz. The predicted MUF over a 3,000km path fluctuated between 15MHz and 19MHz for the whole day, which meant only 14MHz was open reliably. As a result, QSOs were hard to come by and many stations reported that it was slow going with virtually no signals from outside of Europe.

So what happened? Well, it was a combination of factors. The increased Kp index, due to a fast solar wind, took its toll. And we are now moving to a summer ionosphere, where chemical changes make it harder to ionise. This will mean we should see MUFs dropping as the season progresses, at least during the day. Nighttime MUFs will be higher than in winter.

So it may be that the glory days of 28MHz F2-layer propagation are on hold until Autumn, with only short-skip Sporadic-E on the 10m band to keep us entertained.

F2-layer propagation is still available on the higher HF bands, but it may be patchy.

International Marconi Day station GB0CMS in Caister, Norfolk, reported that its 20m signals were picked up by a reverse beacon network skimmer in Utah, despite not working anyone outside of Europe. Meanwhile, on the morning of the 2^nd, Laurie, G3UML was quite surprised to work YJ0CA on Vanuatu on the 15m band using SSB. He also worked 3D2CCC on Conway Reef on the 20m band using CW, and JD1BMH in Japan on the 15m band, also using CW.

Next week NOAA predicts the solar flux index will be in the 125 range, rising to 175 as the week progresses. Geomagnetic conditions are dependent on coronal mass ejections. We have had eight M-class solar flares in the past three days, and a Kp index of 5 on Thursday the 2^nd, which doesn’t bode well for next week. So, keep an eye on solarham.com for current conditions and look for the best HF propagation if the Kp index is low for a day or two.

And now the VHF and up propagation news from G3YLA and G4BAO

The weather pattern remains very unsettled for the whole period with areas of low pressure edging north across the UK from the continent.

There will be a risk of thundery weather at times with locally heavy rainfall, which will be good for rain scatter on the Gigahertz bands. Tropo looks to be hard to find as we end the current week dominated by low-pressure systems, but there are signs of high pressure returning after mid-week, but only temporarily.

This could produce some Tropo paths, especially across surrounding waters such as the Irish Sea, English Channel and North Sea.

The nominal summer season of Sporadic-E propagation is upon us and, from May to early September, daily blogs will be provided on the Propquest.co.uk website highlighting the possible Sporadic-E links to the position of the jet streams shown on the upper air charts.

It’s well worthwhile getting into the habit of regularly checking the DX clusters and activity maps, since the early season is usually characterised by a complex jet stream pattern with multiple potential locations for Sporadic-E propagation. 

Timewise, it eventually settles into a more traditional behaviour with activity often in two phases, one in the morning and the second in late afternoon, early evening.

As you listen to this report, the Eta Aquariids meteor shower should be peaking. Unfortunately, the best viewing for the shower, which is part of the debris from Halley’s comet, will be in the southern hemisphere.

Nevertheless, this is expected to be one of the best showers this century. For those viewing the shower, a waning Moon means that light levels should be low, making for ideal visual sighting.

For EME, the Moon will be waning all week with the new Moon around the 8^th of May. The Moon will be rising in the sky throughout the week, with zero declination on the 5^th of May and peaking at its highest in the sky on Saturday the 11^th of May.

The lowest additional path loss occurs today and tomorrow, the 5^th and 6^th, but high Sun noise, with the Moon close to the Sun at new Moon, occurs shortly afterwards. Later in the week, as the Sun 'leaves' the Moon behind, noise levels, at least on the higher bands will fall to around normal.

And that’s all from the propagation team this week.
