Airband News A Parallel Runway Take-off and Military Airspace DAVID SMITH REPORTS ON A HEATHROW CELEBRATION AND AN RAF DRIVE FOR NEW AIRSPACE. HE ALSO DESCRIBES THE CONTINUING EFFORTS TO FIND A MISSING MALAYSIAN AIRLINER AND SHARES SOME ATC FREQUENCIES FOR RAF LEEMING. David Smith dj.daviator@btinternet.com On the morning of 8 November 2021, the reopening of the USA to UK travellers was marked with a spectacular synchronised, parallel take-off from Heathrow – a rare occurrence. Heathrow’s runways are ‘only’ 1,414m apart, which is too close to be able to perform parallel departures outside of some very specific weather and visual conditions. The controllers must rely on what is called ‘Reduced Separation in the Vicinity of an Aerodrome’ to ensure the aircraft remain safely apart as they climb out of the…

This will be an ongoing topic throughout 2022, and it will also include descriptions of different aerials types ranging from the well-known to some of the more unusual types. There will be some formulae – which on a technical subject such as this is unavoidable – but I will keep this to a minimum.…

She also illustrates how individuals can create fame as presenters, on their own terms and through their own channels. Chrissy Brand chrissyLB@hotmail.co.uk CHRISSY BRAND The winter months inevitably draw people indoors, which in turn offers plenty of opportunities to catch up on radio programmes, podcasts and the plethora of other entertainment options and channels in an age of video and audio abundance. There are many podcasts and programmes to uncover that focus on all aspects of gaming.

Maritime Matters Maritime Communications on MF and HF Robert Connolly looks at how to receive maritime voice and data communications on MF and HF, at NAVTEX DXing, Digital Selective Calling, Radioteletype and Radiofacsimile, and SAR ops and cruise ships. Robert Connolly gi7ivx@btinternet.com Winter: The time of the long and dark nights, interspersed with short periods of daylight. While it may not be a good time to head to the coast and listen to marine VHF channels, unless you are fortunate enough to live in a coastal region, it is a time when you can improve your skills at receiving MF/HF maritime communications. The maritime MF and HF bands may not be as active as the equivalent aircraft bands, but there are signals to be received if you know what frequencies to…

Review The Sangean ATS-909X2 The editor has had the brand-new Sangean ATS-909X2 in the editor’s shack and shares his evaluation of this stylish portable world band radio from one of the most traditional and well-known makers on the market. Georg Wiessala wiessala@hotmail.com The Sangean name is a well-known brand, widely recognised by radio enthusiasts, world travellers and short wave listeners. Some of us may have owned an earlier model of one of a range of world band receivers made by the company over the decades. I have fond memories of the ATS-818CS myself – the one with the inbuilt cassette recorder, remember? I have also worked with the ATS-803A (also marketed under the Realistic name) and the model immediately previous to the one reviewed here, the ATS-909X. This new model…

Digital Radio The Future of DAB and a Radio that Knows Your Emotions Kevin Ryan reports on the 2021 WorldDAB Summit, evaluates the latest Digital Radio and Audio Review, has news on a software update for PURE digital radios and looks at a face-scanning ‘emotional radio’. Kevin Ryan kevin@radio-digital.co.uk There was not too much of note in this year’s WorldDAB summit. The group’s objectives over the coming three years appear roughly the same as before. They are, primarily, to ensure that any developments for car radios keep DAB broadcasts as the primary source of audio, and not IP (i.e. the internet). The other objectives are marketing, retaining the countries currently using DAB, and gaining new markets. The ‘receivers’ section of the summit covered marketing initiatives in Germany, the Netherlands, Belgium…

Feature Aerials for the ELF and VLF Bands (Part I) The editor revisits the Very Low Frequency (VLF) part of the spectrum, evaluating the kinds of receivers, aerials and accessories you might find useful if you venture into this fascinating part of the radio hobby. Georg Wiessala wiessala@hotmail.com If you are a regular reader, you will, no doubt, have noticed my interest in the Extremely Low Frequency (ELF, 3-30Hz) and Very Low Frequency (30Hz-30kHz) bands, sometimes referred to as the ‘Basement-Bands’ of radio (Table 1). Radio signals at these extremities (Fig. 1) are fascinating, not just as physical phenomena in themselves, but primarily because they offer so much information about how our world – and the wider universe – are working. It may be useful to remind ourselves of the…

Signals from Space Graveyard Orbits and Infotainment: Two Satellite Radio Stories This month Tim Kirby looks at two different Direct Broadcast Satellite Radio systems – one which has failed but is remembered by many, and one which is still going strong, adapting and branching out. Tim Kirby tim@livingland.wales Broadcasting television signals from space is well known to most of us. If we do not have a satellite dish on the house ourselves, we probably know someone who does. Broadcasting radio signals from a satellite in space is rather less common, though. I will first look at a system that did just that, and which has come and gone. Following that, I will be describing a technology that is running now and assess in what way it has evolved to meet…
