Innehållsförteckning för June 2022 från Radio User

Georg Wiessala wiessala@hotmail.com Hello and welcome to the June edition of RadioUser. With half the year gone already, there are plenty more radio subjects to be covered in the second half, judging by your responses and the many contributions and article proposals I have already received. But staying with the present, we once again offer a smorgasbord of radio topics, which, I hope, you will find both informative and inspiring. In our features section, Alan Pennington looks at the history and technology behind this month’s Antarctic Midwinter Broadcast from the BBC World Service. Ukraine features a few times this month: Martín Butera introduces a strategic radio astronomy facility in Crimea, while Chrissy Brand outlines the wider Ukrainian radio scene, which is undergoing colossal changes. What is more, David Smith follows…

mydogisfinn@gmail.com On David Harris’s desk, this month is a radio presenter’s autobiography, which is also a sensitive treatment of mental health, and social and historical issues. Justin Webb (b.1961) is a presenter for the BBC Radio 4 Today programme. He joined the BBC as a graduate trainee in 1984 and worked as a foreign correspondent in Europe and the USA. This book is an autobiography covering the first 18 years of his life. It is also a meditation on mental illness, safeguarding children and growing up in a dysfunctional family. Justin was born to Gloria Crocombe who was a single parent. His natural father, with whom Gloria had a brief affair, was the BBC newsreader, Peter Woods (1930 - 1995) who took no part in his upbringing. Justin’s grandfather was…

chrissyLB@hotmail.co.uk Radio stations in Ukraine have, inevitably, taken on a more vital role than ever since the invasion by President Putin. New stations have taken to the airwaves and others have changed format, while parts of the outside world recommenced targeting the country with their radio services. The National Radio Company of Ukraine and commercial stations had a key part to play in the ongoing Russo-Ukraine disputes, which have been worsening ever since 2008 (Fig. 1). It has been a challenge for stations in war zones to stay on the air, due to suffering massive bombing and destruction. Many stations have lost staff, who, understandably, fled Ukraine. At the time of writing, Russia has not taken over the Ukrainian broadcasting network or any stations, which continue to relay news and…

chrissyLB@hotmail.co.uk Ordinary people’s views and stories are often missing from conflict situations or, at best, only covered fleetingly. Radio, television and the print media concentrate on the dramatic stories, talking to people who have been bombed out of their cities or forced to flee to another country. There are a great number of people, often young, who have built loyal followings as vloggers. Some of those that I follow have been particularly insightful in recent months. I am not alone in obtaining much information on the Ukraine war through the impressions and videos of individuals who are living through or directly affected by the conflict. These vloggers, granted, perhaps do not all qualify under the definition of ‘ordinary people’. The Ukraine war is probably the first in Europe since the…

A new, and further improved, version of the AN-SOF antenna simulation software suite is now available. Among the new and improved features, the firm has emphasised the following: Access the input impedance and VSWR easily by going to ‘main menu > Results’. This avoids selecting the segment where the source is located to access the input impedance. NEC designs of antennas over real ground can now be imported directly into AN-SOF, through the ‘GN’ command. The complete real-ground description can also be exported to an NEC file. The ‘GN’ command can be exported to a Scilab .sce file to develop scripts and run bulk simulations. Among these improvements, the makers have also fixed some bugs reported by users. Those subscribed to an ‘update-plan’ will soon receive the link to download…

Scottandrew.caldwell@yahoo.co.uk Adolf Karl Heinrich Slaby (1849-1913, Fig. 1) is sometimes regarded as the ‘German Marconi’ who introduced the technological wonder of wireless telegraphy to the then German Empire. His work, and that of others, instigated a race to develop a version of the Marconi’s system, intended solely for the commercial and strategic benefit of the German Empire. The Early Years Slaby’s background was humble; his father worked as a bookbinder. At secondary school, Slaby had already developed a passion for mathematics and technology. He pursued this in his further education, and he enrolled to study mathematics and mechanical engineering at Berlin’s Gewerbeakademie (Academy of Commerce). Unlike ‘pure’ academic researchers, Slaby combined theoretical thinking and practical experiments. He campaigned hard to establish the first chair of electrical engineering at the Kӧniglich-Technische…

NEWS FROM RAOTA JUST OUT: The Summer 2022 Edition of the quarterly RAOTA magazine (OTNews) has been sent to the printers and the RAOTA audio version reader. The aim is that both printed and audio versions arrive with members at the same time. The issue covers an aerial made by G3ZPF back in 1982 called the Winfield Wonder Wire. This is, basically, an 84ft doublet, named after a roll of Woolworth’s ‘own-brand’ bell-wire. Probably not the best material to use, but it was put up to replace its predecessor, which was overcome by the weather. Despite its ‘uninspiring’ construction, the aerial achieved 5 - band DXCC by 1982; and, despite being only 25ft in the air, managed to work ZL on 80m (admittedly, just once). W3WEG continues his ‘Antenna Chronicles’…

The GRG for this summer is now out (4th May 2022). During times of crisis, radio hobbyists turn on their radios and tune to the short wave ‘global’ radio bands for context, perspective, and insight into events from around the globe. With the Russian-Ukrainian war raging on and tensions continuing to rise in other world hotspots, radio hobbyists are still following the latest news from the front lines using short wave broadcasts and other radio services. The world has held its breath during the Russian invasion of Ukraine as images of the human suffering of war have brought back old memories and old fears from years gone by. Just like these events have brought up once buried feelings, it has also brought what many thought to be ‘old’ technology back…

alan.pennington1@ntlworld.com Midwinter’s Day in Antarctica (Tuesday 21st June 2022) sees the biggest celebration of the year at British Antarctic Survey (BAS) research bases in the British Antarctic Territory (Fig. 1). It is bigger than even Christmas Day. For the staff left overwintering there, it is a day to look forward to and prepare for in the middle of their cold winter isolation. At the main BAS base at Rothera on Adelaide Island south of the Antarctic Circle (Fig. 2), the Sun will not appear above the mountains for many weeks; it will not rise at all between 14th and 28th June. Cherished Midwinter’s Day traditions include the exchange of homemade gifts, the base commanders preparing breakfast, and later a multi-course feast. Some of the traditional entertainment includes watching John Carpenter’s…

kevin@radio-digital.co.uk HD Radio – or IBOC (In-Band-On-Channel) as it was once known – is the digital radio standard created for the USA. It has spread to Canada and Mexico too and has been adopted by some countries in the rest of the Americas. I have a good understanding of how HD Radio works but I would like to hear it first-hand. It is not currently possible to experience it in the UK, for a number of reasons. This is also true for DRM on FM. I want to find out how the audio of the HD Radio system sounds, using either an online portal or a decoder of some sort. Unlike DRM and DAB, which are open standards, the HD Radio system is proprietary. DTS, the new owner of the…
