IRTS Radio News Bulletin Sunday August 8th 2021


Sean Ward Ei8EK Silent Key

Paul McGlinchey Ei2KX shares the sad news of the passing of Sean Ward Ei8EK. Sean was licensed in the early 1980s having entered Amateur Radio via 27MHz. He was the principal of St Marys boys school, Stranorlar. His interest in radio lay in antennas and propagation having gained many top DX awards along the way. His musical knowledge was immense, he was bandmaster of the Twin Towns and Donegal youth band simultaneously having started in Ballybofey in the 1960s. He will be fondly remembered by those of us lucky enough to have been taught by him and call him friend.

We shall now observe a minute's silence in memory of Sean Ward EI8EK

Shopping for ham radio equipment in Switzerland gets more complicated

In light of the disruption caused to the supply of radio equipment after Britain left the EU, experimenters in EchoIndia should keep an eye on other countries in mainland Europe. Ed Durrant DD5LP, reporting for USKA, the Swiss national amateur radio society, writes that companies in countries outside the European Union are no longer being permitted to import electronics to customers in Switzerland unless those companies have a business affiliation within Switzerland. The use of a Swiss-based intermediary for companies in those nations became mandatory as of mid-July. Although Switzerland is not part of the European Union, a trade agreement exists between the EU and the Swiss government. The USKA's head of political lobbying, Willi Vollenweider HB9AMC, wrote on the website that the organisation considers this action "of strategic importance" to radio amateurs. Willi noted that the USKA hopes to petition the government, during its consultation period, on behalf of Swiss radio amateurs.

EI6JK is the leading EI operator in WRTC Standings

The World Radiosport Team Championship was conceived as an Olympic style competition among radio contesters, where teams of two compete from the same locations using identical stations, thereby being a true test of operator skills. The championship is held every four years and is run over twenty four hours in conjunction with the IARU HF Championships on the second full weekend in July. The first WRTC was held in Seattle in 1990, San Francisco in 1996, Bled, in Slovenia in 2000, Helsinki, in Finland in 2002, Brazil in 2006, Moscow in 2010, New England, in the USA in 2014, and the last one was in Germany in 2016. The next event was scheduled for Italy in 2022 but this has already been postponed to 2023 due to the Covid-19 pandemic. A qualification for participation in WRTC 2022 is achieved by an operator's results over any 12 contests out of a specified twenty-four, held between November 2019 and November 2020. Our Congratulation go to Mark EI6JK, who is now the leading EI contester from a list of fifty-four. Making up the top five were Neil EI3JE, Mark EI3KD, Dan EI3JZ and John EI8IR. Full results are available on wrtc2022.it


DX spot

As reported last week, ZL1AAO is active as E51AAO from several of the South Cook Islands until the 19 of August.

Bo, OZ1DJJ, is on Tasiilaq Island using the callsign OX3LX between until the 13th of August. He will be found mainly on 6m and 4m but will also be on some of the HF bands. QSL via OZ0J.

Sergey UT8UU is operating as 5H3UU is still active from Tanzania until the end of this week, keep an eye on dx spots for him.


Contesting

The MMMonVHF and DUBUS 144 MHz Meteorscatter sprint contest starts at 1500Z on the 11th of August and runs untils the 13th of August, ending at 1459Z. This contest is not for the casual operator, for less than 1.5kw ERP is considered QRP. Browse their website at www.mmmonvhf.de for more details.

To operate the other end of the power spectrum, digital contester should have a look at www.ft8activity.eu for details on the upcoming ft8 european activity contest this wednesday coming.


The Propagation Horoscope

Indian astronomers have found an explanation why the rotation profile of the Sun changes sharply in some latitudes. It has long been known that the sun's equator spins faster than the poles. An article in the journal Monthly Notices of the Royal Astronomical Society shows how the slight difference in temperature between solar poles and equator is balanced by the centrifugal force appearing due to solar differential rotation.

A view into the internal rotation of the sun using sound waves reveals the existence of a layer where its rotation profile changes sharply. This is called the near-surface shear layer and exists very close to the solar surface, where there is an outward decrease in angular velocity. Understanding this shear layer is crucial for understanding of solar phenomena like sunspot formation, and the solar cycle.

And this new insight may very well inform predictions that solar cycle 25 is heating up faster than expected. The latest sign may be found in sunspot counts from July 2021. Continuing a trend that started last year, they overperform the official forecast issued by the NOAA/NASA Solar Cycle 25 Prediction Panel in 2019.

The official forecast calls for Solar Cycle 25 to peak in July 2025. However, a better fit to current data shows Solar Cycle 25 peaking in October 2024. This is just outside the 8-month error bars of the panel's forecast.

July 2021 was a remarkable month. Solar Cycle 25 crossed multiple thresholds, including its first X-flare and, at one point there were six sunspots on the solar disk. The last time so many sunspots were seen at the same time was during September 2017.

One farside coronal mass ejection in July was so strong it affected Earth despite being on the "wrong" side of the sun, a full circular shockwave was observed, and a handful of other CMEs narrowly missed our planet.

Inspite of all the solar activity last month, the start of August turned out to be rather quiet, at the time of writing the solar flux is 72 and an A-index of 4, meaning a quiet sun and the same average conditions as reported last week. No radio blackouts are expected and no significant active region flare activity is forecast. Also, the currently unsettled weather without any notable high pressure zone in sight makes for a poor tropo forecast, but reasonably good conditions have been reported for both the 10 and 6 meter bands in the past week.
