The news headlines:

  • Midland series ARDF event in Leicestershire

  • Monk Apollo, SV2ASP, Silent Key

  • BBC explains amateur radio emergency comms

 

The first of the Midland series ARDF events takes place on Saturday the 18th of May at Burbage Common, between Hinckley and Earl Shilton in Leicestershire, map reference SP446953. Anyone interested should meet at the visitor centre off the B4668, that’s the old A47, at 10am. Suitable radio receivers will be available on loan. There will be tuition if you would like this and also mentors to help you get started. The 80m band is being used and there will be five transmitters to be located. You will find it helpful to bring a compass with a rectangular base plate, a fine tipped spirit pen and a lightweight A4 board to which you can tape the map that will be provided. Dress appropriately for a walk in the woods. There is a fee of £2 to cover the costs of the maps and incidentals.

Sad news now. Mount Athos’ best-known radio amateur, Monk Apollo, SV2ASP, became Silent Key on the 5th of May after complications resulting from cancer. He was 64. Monk Apollo was essentially the lone DX voice from Mount Athos, the 20th most-wanted DXCC entity, where he operated from his Orthodox Monastery.

An interesting item about amateur radio was broadcast on the BBC World Service this week. It dealt with the importance of amateur radio emergency communications during the recent cyclone in India. You can listen to the broadcast, Digital Planet – Ham Radio Aids Cyclone Relief Effort, at www.bbc.co.uk/programmes/w3csy664

New videos have been added to the RSGB YouTube channel for anyone to view. Dan McGraw, M0WUT presents ‘Designing an HR WSPR Transceiver’ and Noel Matthews, G8GTZ talks about ‘The Farnham WebSDR – DC to microwaves on your smartphone’. Go to www.rsgb.org/videos for these and many more interesting talks.

A BBC Earth PodCast featuring Eleanor Griffin, M6NWZ talking about her experience with an ISS link from Kings High School, Warwick was broadcast this week. Go to www.bbcearth.com/podcast, scroll to the bottom and listen to the one called ‘Looking Up’.

There are several interesting publications available on the IARU Region 1 website at www.iaru-r1.org. You can read the latest edition of the IARU Region 1 Monitoring System newsletter that contains detailed reports from the various national coordinators showing the various stations that have been monitored on the amateur bands and any action that has been taken. The IARU Region 1 VHF newsletter contains reports on the recent IARU meetings in Vienna preparing for the next ITU conference and has details of a 50MHz test that will take place on the 13th of June.

Recently added to the Syllabus 2019 updates on the RSGB website is a presentation on Digital Signal Processing Without The Maths. This is aimed at tutors preparing training material. On the page you will also find the Exam Specifications, details of the Tutors’ meeting in March, and model tutorial slides on SDR and Digital elements.

Now the radio propagation report, compiled by G0KYA, G3YLA & G4DDK on Friday the 10th of May.

Sunspot group 2740 has now returned and is emitting a lot of radio noise. Solarweather.com reports large bursts have been recorded on 20 and 25MHz. The bursts sound like waves breaking on the shore and are caused by beams of electrons accelerated by explosions in the sunspot’s magnetic canopy. As the electrons slice through the Sun’s atmosphere, they generate a ripple of plasma waves and radio emissions detectable on Earth.

The last week saw slightly better HF conditions. Andy, M0NKR reports working Nobby, FW5JG on 20 metres on Wallis and Futuna Islands. Jim, G3YLA also reported working James, K6AR just north of San Diego in California at 1400Z, also on 20 metres.

Sporadic-E has also been growing this week. Beacon signals were logged on 10 metres from Poland on Wednesday, and Spain and Italy on Thursday. The 10m beacons, from 28.160 to 28.325MHz are a good guide to propagation, especially as many of them run less than five watts.

Next week, NOAA predicts the solar flux index will be 76, thanks to the two sunspots groups now visible on the solar disk. A weak, slow-moving coronal mass ejection observed on Tuesday the 7th of May is predicted to deliver a glancing blow to our geomagnetic field this weekend. Otherwise, geomagnetic conditions will be settled with a maximum K index of two next week, although more coronal mass ejections from sunspot groups 2740 and 2741 are a strong possibility. This could lead to an elevated K index and poorer HF conditions in the short term.

Daytime critical frequencies remain in the 4-5MHz range, with the maximum usable frequency over 3,000km occasionally exceeding 18MHz. The night-time critical frequency is mostly now staying above 3.5MHz, which means 80m should remain open to NVIS signals around the UK throughout the night.

And now the VHF and up propagation news.

It’s an unsettled end to the week with further showers for many areas, so there is still some scope for rain scatter on the microwave bands. Some of the showers could be heavy with a chance of hail and thunder, so watch out for rain static.

The big change will come after the weekend when the pressure builds quickly to produce a large area of high pressure over the country and improved weather all round. It also means a good chance of Tropo and maybe checking out those solar panels for your off-the-grid portable set up.

Sporadic-E has been showing its hand during the last week and there should a reasonable chance of jet streams in good locations for further Sporadic-E in the coming week.

Use the Propquest.co.uk website to see the daily updates. Starting this weekend, there will be a jet stream over the Pyrenees that translates east to the Alps. This means we could start off with paths to EA/CT and gradually move to Italy and IS0 in the central Mediterranean.

The Eta Aquariid meteor shower has now peaked, although there are still meteors associated with this shower up to about the 24th of May, so expect to hear some pings throughout this week. We now enter a bit of a lull in shower activity until the July Delta Aquariids.

Full Moon occurs next Sunday, the 19th of May. This is a low declination full Moon, meaning that the moon reaches full illumination at its lowest point in the sky of this lunar cycle. This period should be more favourable for stations without antenna elevation, although the low declination often means more terrestrial obstructions for the antenna view of the Moon. Path loss will increase through the week, as will libration – the Moon’s apparent “wobble” that lets us see up to 59% of its surface.

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