Radio Waves:  Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers.  To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!


Under a darkening sky, earthlings tune in to ‘Jupiter Radio’ (KLCC)

Ever eavesdrop on the planet, Jupiter? This past weekend, some radio enthusiasts gathered at Eugene’s Riverfront Field to do just that.

Roughly a dozen members of the Ducks on the Air Amateur Radio Club gathered on the grassy space (making sure to sidestep goose poops) to set up an array of cables and rods called a differential dipole antenna. They managed to assemble it and realign it just before Jupiter appeared on the dusky horizon. [Continue reading and listen to the audio at KLCC…]

Radio Emma Toc – celebrating wireless station 2MT – at 100! (Southgate ARC)

Dear Listener / Viewer

I’m pleased to let you know that I will be broadcasting another video stream this coming Monday, 14th February, with the theme of celebrating wireless station 2MT.

In 1922, after requests & petitions from radio hams in the United Kingdom, a licence was issued for station 2MT to transmit a programme of CW (morse), Telephony (voice) and music, on a weekly basis. Transmissions came from a small wooden hut in Writtle, Essex, where engineers working for the Marconi Company were given the task of putting on air a wireless station for ‘calibration purposes’ aimed at the growing number of radio hams and enthusiasts.

Over a short period, and with the good fortune of this Marconi team having a selection of gifted radio engineers & maverick individuals, 2MT became incredibly popular & – probably without realising it at the time – went on to lay the foundations of entertainment broadcasting that was to follow.

Monday the 14th February will be the centenary of the first transmission from 2MT. From 11am in the morning – 11:00UTC – we will be playing audio documentaries & videos looking at the start of broadcasting here in the UK, & then at around 6.45pm – 18:45UTC – I will present a live programme where hopefully we can all join in to drink a toast to ‘2MT’.

Our broadcast will not be a full history of the station, more a celebration of the people involved & everything that we enjoy about radio today. I hope to link with others celebrating 2MT & also radio hams on the air on this anniversary day.

I invite you to join me for this amateur enthusiast video broadcast!

Our friends at Essex Ham have produced a short interview video with more detail – https://www.youtube.com/watch?v=uk_XnGvsJ0M

For radio hams, there will be two special event amateur radio stations in operation.
Local Radio Club CARS – Chelmsford Amateur Radio Society – will be operating GB100 2MT from Writtle Village Hall – http://www.g0mwt.org.uk/events/gb1002mt-writtle/index.htm
Radio Club Essex Ham will be operating GB2MTC from the East Essex Hackspace Hut in Hockley – http://sxham.uk/2mt

It is also hoped that items about 2MT will feature in programmes on the 14th on BBC Essex, Chelmsford Community Radio, & Phoenix FM. I will have more detail on this during my live stream, & if possible will link up with our friend Tim Wander at some time during the evening!

I look forward to being with you on the 14th!

DW, VoA and Euronews facing Turkish ban (Broadband TV News)

Turkey has given three international broadcasters a deadline of 72 hours to apply for local licences or be taken off the air.

“Deutsche Welle, Voice of America and Euronews have been given a deadline of 72 hours by the RTÜK. They must apply for a broadcast licence within that period or face a broadcast ban,” said Okan Konuralp, a member of the Turkish opposition Republican People’s Party (CHP) on Twitter.

At issue are the broadcasters’ websites that have drawn the attention of the authorities because they also feature video news. Such websites have become increasingly popular in Turkey as the government places restrictions on local news outlets.

If the broadcasters don’t apply for a licence the regulator has the right to go to court and get the website closed down. [Continue reading…]

RT DE to sue German regulator after broadcast ban (Broadband TV News)

RT DE says it plans to take legal action against Berlin’s media regulator after the German-language channel was ordered to shut down its streaming service.

The simmering row between Berlin and Russia has resulted in the imposition of restrictions on the German international broadcaster Deutsche Welle’s Russian operations.

“We believe that the regulatory authority acted unlawfully with its decision against RT DE Productions GmbH on February 2. The MABB claims that RT DE Productions GmbH is responsible for broadcasting the RT DE channel, blatantly ignoring the fact that the RT DE programme is managed and distributed by Moscow-based TV Novost,” said RT DE in a statement.

Receiving Jupiter with the SDRplay RSP1

I’ve been fascinated with radio astronomy since my university days. In the 1980s and 90s almost any radio astronomy experiment equated to forking out some serious money to purchase a wideband receiver (serious money to a student, at least). With the advent of SDRs, though, radio astronomy has become affordable for everyone.

Many thanks to RTL-SDR.com for publishing the following video and post about monitoring Jupiter radio bursts:

Over on YouTube user MaskitolSAE has uploaded a video showing him receiving some noise bursts from Jupiter with his SDRplay RSP1. The planet Jupiter is known to emit bursts of noise via natural ‘radio lasers’ powered partly by the planets interaction with the electrically conductive gases emitted by Io, one of the the planets moons. When Jupiter is high in the sky and the Earth passes through one of these radio lasers the noise bursts can be received on Earth quite easily with an appropriate antenna

In his video MaskitolSAE shows the 10 MHz of waterfall and audio from some Jupiter noise bursts received with his SDRplay RSP1 at 22119 kHz. According to the YouTube description, it appears that he is using the UTR-2 radio telescope which is a large Ukrainian radio telescope installation that consists of an array of 2040 dipoles. A professional radio telescope installation is not required to receive the Jupiter bursts (a backyard dipole tuned to ~20 MHz will work), but the professional radio telescope does get some really nice strong bursts as seen in the video.

As Carl mentions above, you do not need a professional radio telescope to receive Jupiter noise bursts, a dipole will do.

In fact, the Pisgah Astronomical Research Institute (PARI) has a dedicated Jupiter receiver–a simple SDR kit called the Radio JOVE Receiver which is promoted by NASA. While PARI has the resources to install any number of antennas, PARI uses two simple dipoles which are mounted only a few feet off the ground as their radio telescope. I doubt their investment in the antennas exceeded $50. It works brilliantly.

The Radio JOVE receiver at PARI

I had planned to purchase and build a JOVE receiver (and, for fun, still may!), but it would be much easier to simply use the SDRplay RSP I already have in my shack. What a great project this fall.

Post readers: Please comment if you’ve used an SDR or JOVE kit to receive Jupiter bursts!
