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!

Many thanks to SWLing Post contributors Patrick, Marcus, Mike and Tracy for the following tips:

China bans BBC World News from broadcasting (BBC News)

China has banned BBC World News from broadcasting in the country, its television and radio regulator announced on Thursday.

China has criticised the BBC for its reporting on coronavirus and the persecution of ethnic minority Uighurs.

The BBC said it was “disappointed” by the decision.

It follows British media regulator Ofcom revoking state broadcaster China Global Television Network’s (CGTN) licence to broadcast in the UK.

Separately, the broadcaster Radio Television Hong Kong (RTHK) said it would stop relaying BBC World Service programming in the region, prompting condemnation from the BBC.

China’s State Film, TV and Radio Administration said that BBC World News reports about China were found to “seriously violate” broadcast guidelines, including “the requirement that news should be truthful and fair” and not “harm China’s national interests”.

It said that the BBC’s application to air for another year would not be accepted.

The BBC said in a statement: “We are disappointed that the Chinese authorities have decided to take this course of action. The BBC is the world’s most trusted international news broadcaster and reports on stories from around the world fairly, impartially and without fear or favour.”[…]

In Our Time: The Invention of Radio (BBC Sounds)

Melvyn Bragg and his guests discuss the invention of radio. In the early 1860s the Scottish physicist James Clerk Maxwell derived four equations which together describe the behaviour of electricity and magnetism. They predicted the existence of a previously unknown phenomenon: electromagnetic waves. These waves were first observed in the early 1880s, and over the next two decades a succession of scientists and engineers built increasingly elaborate devices to produce and detect them. Eventually this gave birth to a new technology: radio. The Italian Guglielmo Marconi is commonly described as the father of radio – but many other figures were involved in its development, and it was not him but a Canadian, Reginald Fessenden, who first succeeded in transmitting speech over the airwaves.

World Radio Day 2021: Radio creates diversity and connects people (RADIOZENTRALE GmbH)

World Radio Day 2021: Radio creates diversity and connects people

World Radio Day will be announced by UNESCO for the tenth time on February 13th and once again refers to how important radio is for society and why it connects people.

Time to celebrate: UNESCO has proclaimed World Radio Day for the tenth time. In Germany, radio has been the everyday companion of people for a hundred years and, more than ever, radio is the medium of the hour. So this jubilee round provides many good reasons to pause and ask what radio means for each individual, society and the world. Radio itself does not take a break, it is on the air – every day and around the clock. Radio informs, entertains and offers a variety of programs, opinions and content. As a matter of course – and yet so indispensable – radio, both large and small, is the vital voice of people and for people.

At the global level, radio remains the most widely consumed medium

The world is changing rapidly. Social and political processes are becoming more dynamic due to new technologies, the communication network is getting faster and bigger and the challenges are becoming more important. In these processes, radio not only offers diversity, classification and orientation, but is also an integral part of opinion-forming because it is the platform for democratic discourse. This unique ability to reach a wide audience means radio can shape a society through diversity and is the place for those who want to speak up.

100 years of radio in Germany

In Germany, the medium for the ears and the head cinema is celebrating its centenary this year. The innovative strength of the medium and the trust base with listeners that has grown over the decades make it possible for radio to be the medium of the hour more than ever. It is the last mass medium and at the same time can digitally reach everyone with the entire range of offers. Radio is at eye level with people – both in terms of content and technology. Because just as society and people’s everyday lives have changed dramatically, so too have listening habits and content. What remains, however, is the great art of putting complex topics into understandable words and giving diversity a voice.

“Today we are experiencing that the world is changing rapidly. We face major challenges when I think of climate change, the current corona pandemic or the debates on racism, for example. The task of radio here is to inform and classify. To make the soft tones heard and to reflect the diversity of opinions, ”says Grit Leithäuser, Managing Director of Radiozentrale. “But the most important thing is to act at eye level with the listeners. This grown connection and mutual trust are something for both sides that one should be aware of and that it has to be preserved every day. Then, in a hundred years, radio will be the medium for people who listen on whatever technical route, in order to learn from one another and to live diversity. ”

World Radio Day was first proclaimed by UNESCO in 2012 and this year it has the motto: “New World, New Radio”. At the suggestion of Spain, the General Conference of UNESCO initiated World Radio Day in memory of the founding of United Nations Radio on February 13, 1946. The aim of the day is to make the public and the media more aware of the importance of radio, to the decision-makers Encourage information to be established and made accessible through the radio.

Further information on World Radio Day can be found at: https://en.unesco.org/commemorations/worldradioday

The generic initiative Radiozentrale sees itself as a common platform for public and private radio stations as well as generic companies in the radio industry. The radio center has set itself the goal of positioning the medium of radio and providing comprehensive information about the (advertising) medium of radio. More information: www.radiozentrale.de

DJ Broadway Bill Lee talks about today’s radio, AM DXing and much more (Stars Cars Guitars via YouTube)

Broadway Bill Lee raps to Alex Dyke about growing up in Cleveland, the impact of the Beatles in 1964 and honing his craft as a DJ. Bill remembers being on-air in New York City the night that John Lennon was murdered and how he felt compelled to take to the air on September 11th 2001.

Today is World Radio Day 2021

2 Replies

Today is UNESCO World Radio Day and this year the theme highlights diversity on the airwaves. Here’s the announcement from UNESCO:

Proclaimed in 2011 by the Member States of UNESCO, and adopted by the United Nations General Assembly in 2012 as an International Day, February 13 became World Radio Day (WRD).

Radio is a powerful medium for celebrating humanity in all its diversity and constitutes a platform for democratic discourse. At the global level, radio remains the most widely consumed medium. This unique ability to reach out the widest audience means radio can shape a society’s experience of diversity, stand as an arena for all voices to speak out, be represented and heard. Radio stations should serve diverse communities, offering a wide variety of programs, viewpoints and content, and reflect the diversity of audiences in their organizations and operations.

CELEBRATIONS IN 2021
On the occasion of World Radio Day 2021 (WRD 2021), UNESCO calls on radio stations to celebrate this event’s 10th anniversary and the more than 110 years of radio.

This edition of WRD is divided into three main sub-themes:

EVOLUTION. The world changes, radio evolves.This sub-theme refers to the resilience of the radio, to its sustainability ;

INNOVATION. The world changes, radio adapts and innovate.Radio has had to adapt to new technologies to remain the go-to medium of mobility, accessible everywhere and to everyone;

CONNECTION. The world changes, radio connects.This sub-theme highlights radio’s services to our society—natural disasters, socio-economic crises, epidemics, etc.

AS mentioned in a previous post, I also suggest you checkout this documentary produced by our friend, David Goren:

World Wide Waves: The sounds of community radio

We may think we live in a digital age, but only half the world is currently online. Across the globe, small radio stations bind remote communities, play a dazzling array of music, educate, entertain and empower people to make change. Cameroon’s Radio Taboo, in a remote rainforest village 100 miles off the grid, relies on solar power; its journalists and engineers are all local men and women. Radio Civic Sfantu Gheorghe in the Danube Delta preserves the history of the community. Tamil Nadu’s Kadal Osai (“the sound of the ocean”) broadcasts to local fishermen about weather, fishing techniques—and climate change. In Bolivia, Radio Pio Doce is one of the last remaining stations founded in the 1950s to organise mostly indigenous tin miners against successive dictatorships. And KTNN, the Voice of the Navajo Nation, helps lift its listeners’ spirits in a time of loss and grief.

WRTH 2021: A look inside the 75th Anniversary Edition!

7 Replies

Last week, I received a long-awaited Christmas gift: the 2021 World Radio TV Handbook. Normally, I’d receive this annual guide in the December time frame, but because of delays in international postal services due to the Covid-19 pandemic, I took delivery a few weeks late.

I always look forward to receiving this excellent staple radio reference guide–and this is their 75th edition! As I say each year, the WRTH has never disappointed, so my expectations are always quite high.

Once again, the WRTH lived up to my expectations.

WRTH’s team of noted DXers from around the world curate frequencies and broadcaster information by region; while I’m not sure how they orchestrate all of this, the end result is truly a symphony of radio information. In addition to broadcaster listings, WRTH’s radio reviews, feature articles, and annual HF report make for excellent reading.

But the WRTH isn’t just a frequency guide: the publication always devotes the first sixty or so pages to articles relating to various aspects of the radio hobby. Following, I offer a quick overview of these.

The first article always features a WRTH contributor: this year, they feature Stig Hartvig Nielson. His path to becoming a WRTH contributor began in his childhood when he said he was “tall enough to reach the radio tuning knob and tune away from dull Radio Denmark.” His love of radio lead him down the path of becoming a broadcaster. Many of us know him via his station, Radio208.

WRTH Reviews

The second set of articles is always my favorite: WRTH receiver reviews.

This year, WRTH begins with an in-depth review of the AOR AR5700D wideband communications receiver–a radio I’d likely never touch in real-life, so it’s wonderful to take such a deep dive. Next up is a review of the Bonito NTi MegaDipol MD300DX antenna which gets high marks for high gain, low noise, and good dynamic range. The following in-depth review is of the benchmark Icom IC-7610 general coverage transceiver. This was the first time I’ve read a review of this SDR transceiver with radio listeners in mind. WRTH then review the Bonito NTi CCMC30 common mode noise filter–a tool that can help radio enthusiasts mitigate RFI.

A review of the SDRplay RSPdx follows and the review speaks to the performance improvements included with the new HDR mode. The next review is actually one I authored of the Tecsun PL-990 portable radio–it’s always an honor to be in the pages of the WRTH!

The final review is of the Valent F(x) KiwiSDR; a little web-connected SDR receiver that has certainly transformed the nature and accessibility of remote listening.

WRTH Features

The first feature article, written by none other than Dave Porter, focuses on the development of HF broadcast transmitters. This article adds to the one he authored last year which focused on broadcast antennas. Dave is amazing because he has such an extensive history in the world of HF broadcasting and his experience and expertise are obvious in all of his writing. This is a must-read for those who want to know more about the “business side” of an international broadcast signal!

Manfred Rippich’s feature, Radio in Bhutan, explores the story of broadcasting in one of the most mountainous countries in the world where communities–including the capitol–are not easily accessible. Radio broadcasting plays an important role in this amazing country.

The following feature, Coastwatchers & the AWA Teleradio 3BZ written by Dr Martin Hadlow, takes a look at the importance of portable radios in the Pacific War. An absolutely fascinating piece for those of us who love radio history.

The final feature was written by Alan Pennington and explores the dynamic Scandinavian Weekend Radio. It’s hard to believe SWR has celebrated 20 years on the air as of 2020. Pennington’s article explores the grassroots energy of this unique broadcaster!

The final article–a tradition–is the WRTH HF propagation report/forecast by Ulf-Peter Hoppe. Always an informative read especially as we continue to work our way out of a long-term solar slump.

The 75th is another fantastic edition of the World Radio TV Handbook. As I say every year, I’ve never been disappointed with WRTH. Their publishing standards are such that the quality of their reviews, their writing, and (most importantly) their broadcast listings are simply unparalleled.

For DXers who collect QSL cards, you’ll find that broadcaster contact information in WRTH is often more up-to-date than a broadcaster’s own website. When readers contact me asking for QSL information from an obscure broadcaster, the first place I search is the current WRTH. Remember: their information is based on volunteer contributors who specialize in specific regions of the world–the most knowledgeable regional DXers keep this publication accurate.

Purchase your copy of WRTH 2020 directly from WRTH’s publishers, or from a distributor like Universal Radio (US) , Amazon.com (US), or the Book Depository (international).

Any experience with the Tecsun TU-80 enthusiast-grade FM tuner?

11 Replies

Many thanks to SWLing Post contributor, George, who writes:

Hi Thomas -I hope you’re keeping well.

[…]I have had my eye on the Tecsun TU-80. However, I seem to find no videos on its use and no reviews. Perhaps it’s because it’s new.

I wonder if any of the SWLing Post readers have some info about it.

Post readers: If you have any experience using the Tecsun TU-80 FM tuner, please comment. I am not familiar with it. Very curious if it might be a great dedicated FM DXing receiver. It is pricey ($530 US on eBay).

Many thanks for SWLing Post contributor, Zack Schindler, who shares the following:

Sangean released a new MW/FM/HDRadio this year, the SG-108: https://www.sangean.com/products/product.asp?mid=261&cid=3

It seems to be identical to the HDR-14 except for the color https://www.sangean.com/products/product.asp?mid=230&cid=3.

I wonder if the receiver is any better than the HDR-14? I have an HDR-14 and am amazed by its performance every time I use it.

Thanks for the tip, Zack! I, too, love the HDR-14. I also love the fact the SG-108 still uses AA batteries as well.

Radio Waves: Stories Making Waves in the World of Radio

Many thanks to SWLing Post contributors Dennis Dura, Ronald Kenyon, Michael Guerin, and the Southgate ARC for the following tips:

Commentary: “The Old Goats Are Going Away” (Radio World)

Broadcasters need to act to refill our ranks before the dial goes quiet

I see trouble ahead in our business in the shortage of qualified broadcast engineers.

I am not speaking of IT people. I am speaking of the guy in a T-shirt and jeans who gets to the transmitter, looks for the problem, reads the schematic, crawls inside the box and replaces R-16, R-17, C-232 and Q-4, and the music again blares forth.

We are losing those guys every day, and they are being replaced by the guy who walks into the site, looks at the box, grabs his cell phone, calls BE or Nautel to find which board to pull, and ships it back while waiting for a loaner to get the rig going.

I never thought of myself as an old-timer. Starting in the business in 1963, old-timers were the guys I learned from, mostly World War II graduates. They knew everything about audio and RF. I wished I knew a tenth as much as they did.

My first real bit of engineering was converting a 50 kW FM station to stereo in 1963. No one listened to FM then, I think there were 10 FM radios in the city and five were in Cadillacs owned by mob hit men.

I remember putting the stereo generator in an eight-foot rack. It took up four feet of the rack and had enough 12AU7s in it to heat the building. It had two outputs, one L+R that went into the phase modulator of the serrasoid exciter and the L–R output that went into the exciter about 200 multipliers later (the crystal frequency was multiplied 864 times).

It was a technical nightmare compared to mono FM. Getting two matched phased phone lines from the studio to the transmitter over three exchanges was another task. But we were stereo most of the time.

The FCC had a rule that if you weren’t transmitting stereophonic program material for more than a certain length of time, you had to shut the stereo pilot off so as not to mislead the 10 listeners by illuminating their stereo beacon. So the pilot on/off was wired into the old Rust remote control so the studio could turn it off when a monophonic recording of a symphony played.

Times changed; we wound up with RF STLs, stereo generators on a single chip, CD players, computers and lots of stuff made in foreign countries that wasn’t worth fixing or whose parts were not available, so when they broke they wound up on a shelf at the transmitter site.[…]

Voice of America CEO Accused Of Fraud, Misuse Of Office All In One Week (NPR)

Fresh crises and fresh challenges confront the Trump-appointed CEO of the parent of Voice of America, even with less than two weeks left of the Trump presidency.

To start, the Attorney General of the District of Columbia this week accused U.S. Agency for Global Media CEO Michael Pack of illegally funneling more than $4 million to his private documentary company through a not-for-profit that he also controls.

Then, five recent chiefs of Radio Free Europe/Radio Liberty – appointed under Democratic and Republican administrations – jointly warned President-elect Joe Biden that Pack poses “a long-term threat to the credibility and professionalism of the five networks” he oversees.

And now Pack is now being accused of trying to propagandize the Voice of America by a group of whistleblowers. They take exception to a planned appearance by Secretary of State Mike Pompeo at VOA’s Washington headquarters on Monday, just nine days before the Biden administration begins.

Pompeo will soon be out of his job. And it’s expected Pack will be replaced promptly as well. But he has sought to outlast his time in office by burrowing himself and conservative allies into boards that will steer Radio Free Europe/Radio Liberty, Radio Free Asia, and the Middle East Broadcasting Networks. The not-for-profit broadcasters are all funded by the federal government through USAGM.

Those networks, along with VOA and the Office of Cuba Broadcasting, collectively reach more than 350 million people across the world each week. They historically have demonstrated American pluralism by providing balanced coverage of news events and robust political debate, regardless of how it reflects on current government officials. The broadcasters are also intended to serve the citizens of nations which do not allow journalists to operate freely.[…]

Radio imports (Southgate ARC)

Now that the United Kingdom has left the European Union, we will see major changes in importing radio equipment.

Definitive information is scarce but imports from the UK can have VAT paid on purchase or depending on the retailer, VAT may have to be paid before delivery. If it comes via An Post, any charges will have to paid before the item is sent out for delivery.

The Post Office employees will not be collecting money at the door. Whether duty is also collected is not very clear, but some sources say that anything originating outside the European Union will attract duty as well as VAT. There may also be a handling charge.

John EI7GL has compiled a list of radio and electronic dealers based in the European Union on his blog page and would welcome any updates you can supply.[…]

TV drama about murder of radio ham G0HFQ (Southgate ARC)

On Monday, January 11, ITV will be broadcasting the first of a three part TV drama about the murder in June 1989 of Oxfordshire radio amateur Peter Dixon G0HFQ and Gwenda Dixon who were on holiday in Pembrokeshire

In the November 1989 Radio Communication magazine the RSGB asked:

Did you work GW0HFQ/M ?

As we’ve reported in previous editions of RadCom, Peter Dixon, G0HFQ. and his wife Gwenda were brutally murdered whilst on holiday in South Wales last June. Dyfed-Powys Police have asked us to say that they are still anxious to talk to anyone who had a contact with Peter whilst he was operating in Pembrokeshire as GW0HFO/M on 7 or 14MHz SSB. 28MHz FM/SSB or 144MHz FM. The dates between which they’d like you to check your logbooks are 19-29 June 1989.

Dyfed-Powys Police believe that Peter Dixon had a contact with another mobile station in the area on 28MHz FM on the morning of Wednesday 28 June.

The drama will be shown on ITV at 9pm on Monday, January 11, details at

The export version of the Tecsun PL-330 has landed

37 Replies

Tuesday evening, I picked up a package from Anon-Co with the new export version of the Tecsun PL-330 inside. Anon-Co sent this unit to me for evaluation at no charge to me. Anon-Co will start shipping the PL-330 next week and the price will be $59.99.

By request, I took a few photos of the PL-330 as I unpacked it. This should give you an idea about how the radio is packed and what is included in the Anon-Co package:

The Anon-Co PL-330 package includes:

Tecsun PL-330 receiver
an English owner’s manual
a brown synthetic velveteen carry pouch
MicroUSB charging cable
earphones

My first thought? It looks like a mini PL-990!

The PL-330 is powered by one BL-5C battery pack. To meet shipping regulations, the BL-5C is not pre-installed–you’ll need to do that yourself.

Note that the PL-330 lacks a fold-out back stand. That is unfortunate

On the air

Unfortunately, I’ve had no proper time to evaluate the PL-330 (comparisons) yet as this is an incredibly busy week for me.

I did, however, listen to the PL-330 as I worked outside all day Wednesday. Sadly, there was a lot of news to follow here in the States that day.

I was able to receive all of my benchmark local and regional AM and FM stations with no problem. For day-to-day broadcast listening, it seems to be a solid portable.

It’s still early days, but I think the PL-330 may be one of the best portables for FM I’ve tested in a while. On Wednesday, I tuned to WFAE in Charlotte a number of times throughout the day and the PL-330’s lock on the station was rock-solid. WFAE’s transmitter is just over one hundred miles from my home, so this is typically a tough catch if I’m inside my home or my car, etc.

The real test? I can also receive WFAE with the PL-330 in my kitchen window. Again, only a small number of portables can reliably grab WFAE’s signal from that spot. Indeed, the PL-330 almost receives WFAE as if were a local station.

While this is far from a laboratory test, it is certainly a real-world test for this radio enthusiast.

I’ve yet to dive into the shortwaves, although I’m incredibly curious how well the sync lock might work. I’m keeping expectations low–after all, this is a $60 radio. The price point is quite good for sporting upper and lower sideband reception, let alone synchronous detection.
