Exploring a 1 Million Watt Broadcast Tower (Radio World)

The father and son team of Joe and Jeff Geerling have teamed up on radio-related projects before.

Joe is a broadcast engineer, working into his fifth decade in the St. Louis market. He was market chief for CBS Radio for 20 years and today is the director of engineering for Covenant Network.

His son Jeff has spent nearly 15 years as a software architect and developer. He founded Midwestern Mac LLC and is active in many open-source software communities. Jeff recalls that one of his first web programming projects in the late 1990s was to construct an interface to display the current song on 98.1 KYKY(FM)’s initial website for his dad.

Last February, Joe appeared on a video on Jeff’s YouTube channel to install a Raspberry Pi IP KVM in a Covenant Network studio. That collaboration went so well that commenters on Jeff’s videos began clamoring for more appearances by the senior Geerling.

Over a family vacation, Joe and Jeff came to the realization that the iconic Crestwood Master Tower in Shrewsbury, Mo. — nicknamed by its original engineering community as “the Supertower” — would make for a perfect showcase for a new Geerling Engineering YouTube channel.

Given Joe’s expertise with the site, the idea for a video was a natural. In fact they ended up making two. [Continue reading…]

Amancio Ortega is testing the purchase of a former BBC headquarters in London for almost 90 million (West Observer)

The investment activity of Amancio Ortega in the United Kingdom does not stop. Pontegadea, the group that manages the equity investments of the founder of Inditex (Zara, Massimo Dutti, Bershka…) and the richest man in Spain, is negotiating the purchase of a new office building in London, as revealed on Wednesday by the specialized website CoStar News. This, citing market sources, indicates that the operation would be around 80 million pounds (89.7 million euros, at current exchange rates). The building, originally a printing press built in the twenties, is close to the BBC headquarters and, in fact, for years served as offices for the commercial division of British public broadcasting.

The property, renovated in 2015 by the construction company Kier and the firm Brimelow McSweeney Architects, currently houses a business of coworking (flexible office rental). Of the more than 3,000 meters built, 2,100 are available for rent, according to the building’s commercial brochure. Some websites advertise their tables for a price that exceeds 840 euros per table per month. It offers, in addition to parking for bicycles or changing rooms, a kitchen, private offices, meeting rooms or terraces on the upper floor (the fifth) and on the roof. To this we must add a privileged location in the center of the British capital, in the Fitzrovia neighborhood. The building is close to Soho, the British Museum and Regent’s Park.

What’s Going To Happen To Legacy Broadcast Bands When The Lights Go Out? (Hackaday)

Our smartphones have become our constant companions over the last decade, and it’s often said that they have been such a success because they’ve absorbed the features of so many of the other devices we used to carry. PDA? Check. Pager? Check. Flashlight? Check. Camera? Check. MP3 player? Of course, and the list goes on. But alongside all that portable tech there’s a wider effect on less portable technology, and it’s one that even has a social aspect to it as well. In simple terms, there’s a generational divide that the smartphone has brought into focus, between older people who consume media in ways born in the analogue age, and younger people for whom their media experience is customized and definitely non-linear.

Replacing Humans “Is the Furthest Thing From Our Mindset,” Says the Company Selling an A.I. Radio Host

RadioGPT can talk. It can research. It can take your calls. And it could be coming to your market.

The humble broadcast-radio host, whether a disc jockey or interviewer or reporter, has been going through it for decades now. The 1996 Telecommunications Act fueled the consolidation of local stations, decimating their staffs. The explosion of online radio, music and video streaming, and podcasting have upended ratings for shows on public airwaves. Phones and computers and smart speakers increasingly supplant radio sets. Funding for public radio is notoriously unreliable. It isn’t the best time for your modern-day Wolfman Jacks, or for any media profession.

On top of all that, your local DJ was already on the losing end of the artificial-intelligence revolution. Before the A.I. hype from last year, and even before the COVID recession demolished media ad markets, broadcast networks were gutting on-air talent at the both the national and collegiate level to trim budgets and automate programming: syndicating well-known shows and brands, prerecording and prearranging late-night broadcasts, training a roboticized voice to fill in the space when needed. Coupled with major streaming services’ dependence on algorithms and automation to curate playlists and make user recommendations—often with bizarre side effects—these developments make clear that the music industry anticipates the need for fewer humans down the line.

A.I. hasn’t yet finished killing the radio star, nor is it truly likely to anytime soon. But there’s a new digital buddy out there that might give hosts additional pause: RadioGPT, a new tool from the Ohio-based software company Futuri Media that fully digitizes the broadcast host as you know it.

Survey: What type of radio is your daily driver?

29 Replies

A little over a week ago, many of us participated in the 2023 Virtual Winter SWL Fest.

I enjoyed all of the presentations and the casual conversations many of us had in the hospitality lounge and various break-out rooms. Again, kudos to the Fest organizers and all of the volunteers who moderated the various rooms and forums–you all did an amazing job!

The one thing I always pick up when hanging with other radio enthusiasts is the type or class of radio they tend to operate the most.

Case in point: I noticed one friend is currently enamored with tube/valve radios–in past years he loved compact DSP portables. Another friend switched from using primarily a portable radio to a Drake R8 series tabletop radio.  I noticed that many others have been bitten the SDR bullet since last year.

Daily drivers

For many of us, the type of radio we use daily changes over time.

For example, when I first started listening to shortwave in my youth my daily driver was a portable radio. When I got my ham license I found that I enjoyed using my general coverage transceiver connected to a multi-band doublet. Later, with the advent of Software Defined Radios, I became an avid SDR enthusiast.

At present, I’m back to using general coverage transceivers (specifically, the Icom IC-705).

Of course, I always have portables and vintage radios on the air, but they’re not my primary, or “daily driver,” these days. 

Survey

I’m curious: what’s your daily driver?

I’ve created a short survey. If you’d like to participate, simply enter your answer in the form below, click the submit button and it will tally the results. Alternatively, you canclick on this link to open the survey form in a new tab/window. Of course, feel free to comment on this post as well! Thank you!

Paul’s recording of the Voice of Korea with a Tecsun PL-330

Carlos Latuff’s artwork from a Feb 9, 2023 VOK broadcast.

Many thanks to SWLing Post contributor, Paul Jamet, who writes:

Hello Thomas

To complement the article Carlos’ Shortwave Art and recording of the Voice of Korea, I send you a recording of the Voice of Korea made with a TECSUN PL-330 with a 23-foot wire antenna:

February 9, 2023 – 04:12:00 p.m. UTC – Frequency: 12015kHz

The announcer describes in laudatory and emphatic terms the recent solemn military parade which took place on the night of February 9 to 10 in Kim il-Sung square in Pyongyang. I recorded for 5’40” in order to show the stability of the signal (no fading) but the recording is too long, at least I think so. It’s up to you to cut if this recording catches your attention

The receivers may have improved but I believe that North Korea now uses more modern and more powerful transmitters (200 kW according to the site www.short-wave.info).

Best wishes.

Thank you for sharing, Paul!

RNZ: “Signal to noise – is AM radio really under threat?”

Signal to noise – is AM radio really under threat? (RNZ)

Old-fashioned AM radio was an information lifeline for many during Cyclone Gabrielle when other sources wilted without power. Now a little-known arrangement that puts proceedings of Parliament on the air has been cited as a threat to its future. But is a switch-off really likely? And what’s being done to avoid it?

“Government websites are a waste of time. All they’ve got is a transistor radio – and they need to actually provide a means for these people who need the information to damn well get it,” Today FM’s afternoon host Mark Richardson told listeners angrily on the day Cyclone Gabrielle struck.

He was venting in response to listeners without power complaining online information was inaccessible, and pleading for the radio station to relay emergency updates over the air.

Mobile phone and data services were knocked out in many areas where electricity supplies to towers were cut – or faded away after back-up batteries drained after 4-8 hours. In some places FM radio transmission was knocked out but nationwide AM transmission was still available.

“This will sharpen the minds of people on just how important . . . legacy platforms like AM transmission are in Civil Defence emergencies,” RNZ news chief Richard Sutherland told Mediawatch soon after. [Continue reading at RNZ…]

Radio Waves:  Stories Making Waves in the World of Radio

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 Dennis Dura, ______ for the following tips:

Third largest structure in Iceland demolished (RUV English)

Once ubiquitous, few radios now receive long wave broadcasts. Priority is now given to boosting FM signals. RÚV’s long wave transmitter in East Iceland has been demolished.

Monday saw RÚV’s East Iceland long wave transmitter switched off. The mast at Eiðar, at 218 metres the third tallest structure in the country, transmitted RÚV’s radio services across the east of the country and out into the Norwegian Sea. In a statement, RÚV say that the equipment needed to maintain the service is very expensive, and few radios now receive long wave broadcasts.

The change is being made in association with Iceland’s Civil Defence and other bodies concerned with emergencies, as long wave signals have traditionally formed part of emergency communication planning. However, an upgraded FM system will take over this function.

The long wave signal from Eiður, on 207kHz, has been replaced by a more powerful FM network in East Iceland. RÚV has increased the number of FM transmitters and renewed existing masts. Long wave transmissions will continue for a time on 189 kHz from Hellissandur at Gufuskálar in West Iceland – Iceland’s tallest structure at 412 metres – but it too will ultimately close, and then the FM system will fully take over the role of safety broadcasts.

Blur’s Dave Rowntree: Long wave radio changed my life – BBC mustn’t switch it off prematurely (iNews.co.uk)

Long wave radio changed Blur drummer Dave Rowntree’s life. Now he warns the BBC not to switch off the shipping forecast signal until the whole country is digitally connected

From childhood to his chart-topping days with Blur, long wave radio has played a central role in Dave Rowntree’s life.

Now the drummer has warned that the BBC’s plans to switch-off the crackly signal could disenfranchise millions of radio listeners who still struggle to receive digital transmissions.

The BBC will end AM radio transmissions – including long wave, home of the Shipping Forecast and medium wave – currently still accessed by an estimated 6.5 million listeners each week.

BBC Radio 5 Live’s medium wave frequencies will fall silent by the end of 2027 with a date for ending long wave currently under discussion.

Rowntree, who holds an amateur radio licence and took inspiration from the shipping forecast for Blur’s hit “This Is A Low”, said the signal should not be turned off prematurely. Continue reading →
