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, Rich Cuff, Ron Chester, and David Iurescia for the following tips:

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.

Follow-up to The Great Medium Wave Daylight DX Challenge

16 Replies

By Jock Elliott, KB2GOM

If the folks who participated in The Great Medium Wave Daylight DX Challenge were on trial for “having fun,” they would be found guilty and sentenced to . . . more DXing challenges!

Results

As nearly as I can tell, 13 people participated, and many had something positive to say about the experience, including they would like to do it again.

I say “as nearly as I can tell” with regard to the number of participants because some people posted the same thing multiple times . . . and there is a simple reason why. When someone posts a comment for the first time, or posts a comment for the first time with a new email address (which is one of the required fields when you post a comment), that comment is sent to moderation for approval before it is posted . . . which causes a delay. Thinking it didn’t work the first time, the commenter reposts again (and perhaps again and again) and after a while, all the posts appear, which confuses the counting process.

A variety of equipment was used: 4 GE Superadios, 2 Belka radios, a Yaesu FT950, an AirSpy SDR, a single-transistor regenerative radio, and a Sangean ATS 909-X2. Some ran barefoot (using internal antennas), some employed loops, dipoles, and even an AFA-200 from Icom.

In terms of station count, Tom Laskowski, in a neighborhood park in South Bend, Indiana, absolutely killed it with a GE Superadio, logging 69 stations with lots of colorful detail. Clearly he was enjoying himself. The total mileage of his top five stations was 1230 miles. He qualified for Chuck Rippel’s generous offer of a Superadio refurb.

13dka “informally reported” his results in miles, furlongs, and attoparsecs. From a dike at the German North Sea Coast (Riddle of the Sands?), his farthest station was 677 miles away and his top five total was 2748 miles . . . that’s 21,968.5 furlongs in case you were wondering. He used a Belka 2022 in combination with an AFA-200 active ferrite antenna (his ultra portable MW rig).

David Mappin in Filey, UK, managed to hear a station in Solt, Hungary, at a distance of 987 miles. His top five total mileage was 1965 miles. He used a Sangean ATS 909X2 with a Cross Country Wireless (CCW) Loop Antenna Amplifier with a one-meter loop made out of coax.

Everyone seemed to have a good time, even those to whom “life happened,” and could only get on for a few minutes.

So, therefore, you are all sentenced to more DX challenges in the future!

My operatives (the upstate irregulars) deep in the underground bunker at El Rancho Elliott tell me that some of the names of future challenges might include “The Midnight Ramble” and “The Grayline Sprint” . . . but these sources are unreliable.

In the meantime, thanks to all for participating, and I am glad you had fun.

PS – Some have suggested that taking station transmit power into account when figuring out scoring might be a thing to do. If you have practical ideas for doing this, post them, with examples in the comments section below. Bear in mind that any calculation of “difficulty factor” will fall on the folks recording their logs.

RadioGPT is a new A.I. radio host system from Futuri Media

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!
