RED ROSE RADIO: Former Rock FM presenter Rob Charles is planning on using the Red Rose Radio name for a new radio station in Central Lancashire. Rob said he wants to launch a new station on the small-scale DAB multiplex licence which has just been awarded to cover the Preston area. Red Rose Radio launched in 1982 and split into Red Rose Gold and Red Rose Rock FM in 1990, but Red Rose Gold became Magic/RockFM2/GHR and Red Rose Rock FM changed to Rock FM. “It’s a dream come true”, said Rob. ”I’ve always wanted my own station, but until recently, unless you were one of the big companies it wasn’t possible.” Red Rose Radio will be aimed at people who used to listen to Rob’s Rock FM shows in…

Garry405625.gs@gmail.com Keith405625.kh1@gmail.com Two new, long-running, programmes began in 1980. The first edition of Newsnight on BBC- 2 appeared on January 30th. The behind-the-scenes dubious activities of fictional government departments and top civil servants were all exposed in the classic comedy programme, Yes Minister. The first episode appeared on February 25th. Although a comedy, the general antics were so accurate that Margaret Thatcher, watched it to see what her reallife colleagues may have been plotting. BBC Radio Norfolk opened on September 11th. This was the first of a new wave of BBC Local Radio stations. November 21st saw the launch of a new major appeal on BBC Television called Children In Need. Since then, the annual shows have raised millions of pounds to help children. Long-Running Comedy and BBC Test Cards…

wiessala@hotmail.co.uk There have been several new noise-cancelling products of late, aiming for both the professional and amateur markets. From within the latter segment, many radio amateurs are known to use some kind of filter or noise suppressing device, to improve the clarity of speech and audio resolution. I have still got the old ERA BP34 in my shack as a simple general audio filter. It was high time for something new. Therefore, when the new Xiegu GNR1 Digital Audio Noise Filter (Figs. 1 and 2) from Nevada Radio arrived here in the editor’s ‘man-cave’ I was keen to put it to use. https://www.nevadaradio.co.uk I have done so, not with a ham radio perspective in mind, but from the point of view of an HF broadcast radio listener or DXer, with…

mallen@panamradio.world It’s 2022, and the debate still rolls on: Is high-frequency (HF) radio still a medium suitable for critical aviation communications? The author regularly sees references, in both trade publications and during meetings, claiming that HF radio as a medium is ‘dead’! However, nothing could be further from the truth; and in some circles, there is even a renaissance of HF activity. HF radio is a mature technology, which is now being improved by the utilization of modern engineering techniques. These can provide a spectrum of service and reliability unavailable with any other service. For several decades, there has been discussion among aviators and communicators, concerning the practical use of HF radio in air traffic control and utility communications for aircraft, both inflight and on the ground. At least twice…

kevin@radio-digital.co.uk The BBC broadcast DRM tests during April from the short wave station at Woofferton, using the retired BBC Hereford and Worcester MW transmitter on 1584kHz. My monitoring of the signal either found it in AM or pure DRM. Reports indicated that some tests might use a simulcast mode but I didn’t detect it. WINB, in Red Lion Pennsylvania (USA), use a simulcast mode allocating 5kHz for DRM and 5kHz for audio on short wave. The transmitter was too far away to monitor the signal here in Reading, and the nearest KiwiSDR I could use was in Rosson-Wye. Unfortunately, the modulation mode used was 16/64 QAM, and that requires a Signal-to-Noise Ratio (SNR) higher than the 12-14 dB SNR usually delivered by the SDR. One afternoon, it peaked at nearly…

chrissyLB@hotmail.co.uk In a strictly ‘non-scientific’ piece of research, we conducted a straw poll of 40 friends, to ascertain their current radio listening habits. Respondents were aged between 24 and 85 years old and did not describe themselves as ‘DXers’ or ‘radio enthusiasts’. Of those that listened regularly to the radio, the preferred ways of listening represented a broad mix. In order of popularity, these methods were: via apps (using tablets or smartphones); live through television (Freeview); smart speakers; on-demand through radio station streaming; or car radio (AM, FM or DAB). Only a quarter owned or used a conventional radio inside the house, with FM and DAB. I think it is safe to predict that by 2042, those that listen to linear radio in the UK on an AM, FM or…

tim@livingland.wales Last time in Signals from Space (RadioUser, May 2022: 53-55), I introduced the iconic radio telescope near Manchester at Jodrell Bank. This time, I am taking a look at the history of another iconic site associated with space communication. Goonhilly Downs is located in the southernmost part of Cornwall. The main use of the site is evolving to meet changing needs and take heed of the advancing nature of space communications. A commemorative event on July 23rd, 2022, will celebrate the 60th Anniversary of Goonhilly Earth Station: Entitled Goonhilly 60 it aims to offer a rare and exciting opportunity to set foot on the historic site to enjoy an ‘interstellar’ programme of curated music, talks and educational workshops.

wiessala@hotmail.co.uk When this little parcel arrived from Nevada Radio, I was keen to open it straight away, attracted by the stylish looks of this unit. Occasionally, I still think of the German term first, and I did so here: the word Alleskönner came to my mind – a ‘multitalent’, or ‘all-rounder’ – and so it proved to be. ‘Degen’ is the name for this brandline; the manufacturer of this radio is Tecsun. The Tecsun Degen DAB119X offers everything modern radio can throw at you. It covers DAB and DAB+ (Channels 5A to 13F), FM (with RDS), Medium- and Short Wave (120m to 11m). There is no Long Wave coverage, and this is not an Internet Radio. However, the Degen DAB119X offers a Line-In socket for external sound sources (MP3 Player,…

dj.daviator@btinternet.com The Ukraine war continues to have a severe effect on flight patterns, especially for those operators banned from Russian and Belarusian airspace. The extra flight time on long haul routes has led to some airlines cancelling connections. For example, Finnair has stopped flights from Helsinki to Beijing, and SAS has ceased flying from Copenhagen to Tokyo. Frankfurt is sufficiently far south that there is no additional flying to reach destinations in India and South-East Asia. Warnings have been issued about several potential hazards to civilian aircraft. Most serious are errors of civil aircraft identification by ground military forces and airborne assets outside the conflict zone. As shown by previous wars, misidentification is easy in confused arenas of warfare. Added to this is the likelihood of the jamming of electronic…

chrissyLB@hotmail.co.uk Have you heard of the acronym ‘GOAT’, often used in the fields of radio and music? It stands for the “greatest of all time” and is in common usage. I most recently saw GOAT used in a promotion for a New Zealand station, Radio Hauraki. When it first took the airwaves, in 1966, Radio Hauraki was an innovative and law-bending station. It was the first private commercial radio station in New Zealand and needed to operate illegally for four years, in order to break the monopoly held by the state-owned New Zealand Broadcasting Corporation. Based in Auckland, it went on to become part of the legal, mainstream rock music radio scene and is now part of the global iHeart radio brand. Making Great Radio In May, Radio Hauraki ran…

Keith.g4miu@gmail.com This month has seen several relevant updates to the most popular aerial modelling software suites. First off, AutoEZ, the Excel application that can automate tasks with EZNEC, has been revised to Version. 2.0.27, dated 11th March 2022, thus superseding the previous release from January this year. https://ac6la.com/autoez.html Next, the team at AN-SOF have been busy improving their simulation software. The latest version is now V7.1. Improvements include a more convenient way to access Input Impedance results. Previously, the user had to navigate to and select the segment where the source was placed, then right-click on this to bring up a menu to access Input Impedance results. Now, once a simulation is run, the user simply selects ‘Results’ then ‘List Input Impedances’ and a task box appears. From here, they…

THE MOST SIGNIFICANT TECHNOLOGY OF WORLD WAR TWO: It wasn’t the Spitfire, the V2 or even the U-boat; it was the radio – at least in Matthew Hill and Landon Johnson’s film Resistance 1942 (right), available now for digital download. Set in war-torn France, this interesting drama looks at the inspirational radio broadcasters who defied Nazi occupation to produce unauthorised programmes and announcements and the personal sacrifices they made to inspire resistance. Resistance 1942 is also known as Burning At Both Ends and under that title is free to view.
