GB2RS Main News for Sunday 12th May 2019

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 GBP 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

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 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, 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 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.

And now for the details of rallies and events for the coming week

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. 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 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 

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.

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> to arrive by
10:00 on the Thursday before transmission.
