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 Todd R, Skip Arey and Tracy Wood for the following tips:

Cracker factory records: the surprising story of United Biscuits’ radio station (The Guardian)

Playing Bollywood soundtracks and songs about safety shoes, this shopfloor station made stars out of Dale Winton and Nicky Horne, and paved the way for UK commercial radio

nless you spent your summers packing Jaffa Cakes into boxes in the 70s, you are unlikely to have heard of the United Biscuits Network (UBN). It was a radio station for biscuit-makers, broadcasting around the clock to factories in London, Manchester, Liverpool and Glasgow. One part industrial psychology, another part community radio, UBN was intended to make factory life more bearable, but over its nine-year lifespan, it emerged as one of the most daring, anarchic and pioneering stations to hit the UK airwaves.

Music has long been a point of contention in the workplace. Prof Marek Korczynski, who co-authored Rhythms of Labour (2013), describes the history of British working life as “a battle over soundscapes”. Bosses first wanted silent factories, but during the second world war, Korczynski says, “industrial psychologists – the forerunners to HR departments – started looking at playing cheerful music in factories, at the times of day when productivity would dip”. After the war, as Britain rebuilt itself, this strategy was maintained with muzak: inoffensive background tunes, played to lighten the monotony of factory work.

There was one issue, according to Korczynski: “Workers grew to hate muzak.” As jobs on the production line were deskilled and made ever more monotonous, muzak’s effectiveness weakened and staff turnover soared. For Sir Hector Laing, the chairman of United Biscuits in the 1960s, stemming the flow – and its cost – was desperately necessary. Drawing on the success of commercial pirate stations such as Radio Caroline, Laing put adverts in Melody Maker, bought state-of-the-art broadcasting equipment and set up his very own station from UB’s headquarters in Osterley, west London (where Sky’s HQ sits today).[…]

Demolition of Bethesda radio towers takes a piece of history, rare open space (Washington Post)

When the four orange and white steel towers first soared over Bethesda in 1941, they stood in a field surrounded by sparse suburbs emerging just north of where the Capital Beltway didn’t yet exist. Reaching 400 feet, they beamed the voices of WMAL 630 AM talk radio across the nation’s capital for 77 years.[…]

Manitoulin boasts Canada’s first off-grid radio stations (Manitoulin Expositor)

LITTLE CURRENT – Great Lakes Country 103 FM and Hits100 FM have opened a new broadcasting studio and office space at the Flat Rock Entertainment Centre, home of Manitoulin Countryfest and Rockin’ the Rock, becoming the first off-grid commercial radio stations in Canada, according to CEO Craig Timmermans.

“It’s super nice to not have an electricity bill anymore,” says Mr. Timmermans as he leads The Expositor on a tour through his company’s new headquarters at 1 Radio Road on the southeastern edge of Little Current.

Through the front doors of the building lies a reception area floating in the centre of a large, open rectangular space. All of the central furniture is moveable so the team can empty the space for special events and small live concerts.

To the right is a small seating area featuring a wood and epoxy tabletop made by Kelly ‘KT’ Timmermans, president of the company. She has also built the live-edge wooden shelving and a table inside the adjacent boardroom.

“This is what I did with my quarantine,” she says with a laugh. “It’s nice to have our own space and to be in charge of our own destiny. We loved being downtown but it didn’t help our business like we had hoped.”[…]

Telecom Egypt signs agreement with St Helena Government to provide it with its first subsea solution (Capacity)

02 November 2020: Telecom Egypt and St Helena Government (SHG) have signed an agreement to connect the Island to Telecom Egypt’s subsea system over the Equiano submarine cable system.

Telecom Egypt will be the first to provide St Helena with a fibre optic connection to the rest of the world, which is a crucial step towards the Island’s economic growth. The cable, along with the associated high-speed internet, is planned to be delivered to the Island by early 2022.

The branch that connects Telecom Egypt’s system to St Helena will be 1,140km long. The cable itself will run from the West Coast of Africa and provide St Helena with access to both Lisbon, Portugal and Melkbosstrand, South Africa with scalable connectivity ranging from a few hundred gigabits up to multiple terabits, as demand varies. It, therefore, provides the most cost effective solution to the growth in the Island’s bandwidth needs.

In light of its vast experience in the subsea connectivity business, Telecom Egypt, in conjunction with SHG, will provide a Dynamic Circuit Network functionality, which will ensure that SHG’s communication partners have access to fixed bandwidth.?Telecom Egypt will also support SHG in the design, installation, and configuration of the submarine and network equipment.[…]

Matt’s Marathon MediumWave Matchup

by Matt Blaze

Here’s another simultaneous receiver comparison, this time of ten portable medium wave receivers plus the Icom IC-R9500 (as a “reference receiver”). Previously, I used the same antenna for all the comparisons, but since these are portable receivers, I wanted to compare their performance using their built-in antennas. I did two comparisons, both of moderate to weak signals, one in the evening of a DX signal and the other in the daytime of a regional station.

The receivers were the Potomac Instruments FIM-41 (a “field intensity meter”), the Panasonic RF-2200, the Nordmende GlobeTraveler Exec (a beautiful German SW portable from 1968), the Sony ICF-EX5MK2, the CCrane Radio 2E, the Sangean ATS-909X, the Sangean D4W, the new Tecsun PL-990X, the XHDATA D-808, and finally the CountyComm GP5-SSB, plus the Icom IC-R9500.

All the receivers were recorded simultaneously. The radios (except the Icom R9500) were on the roof of my building and oriented for best reception (signal/noise) and kept sufficiently away from each other and other metal objects to avoid interference, The R9500 was in the shack and used a Wellbrook loop on the roof, also oriented for best signal/noise. I took the audio from the Line Out if one was available and from the headphone jack (via a “direct box” level converter) if not. I tried to match the audio levels reasonably closely, but different ACG characteristics made it difficult to be completely consistent across all the receivers throughout the sessions.

As in previous comparisons, for each session I’ve got a narrated stereo mix with the R9500 on the left channel and each receiver, for a minute or so one after the other on the right channel. You definitely want to use headphones to listen to these so you easily tell the left from the right radio. I’ve also provided mono “solo” recordings of each receiver for the full 15 minute-ish sessions so you can hear a receiver you’re interested in in detail.

Sound Devices 688 Multitrack Recorder

The recordings were made with a Sound Devices 688 recorder/mixer (which can record 12 simultaneous channels of audio). The portable radios were hardwired to the recorder, and the 9500 (which was downstairs) was connected via a Lectrosonics digital radio link. (Everything except the R9500 was on battery power to avoid mutual interference and ground loops, etc). The narration used a Coles noise canceling ribbon mic. Everything was done in a single take per session – there was NO postproduction editing – so I apologize for a few glitches and awkward moments.

You can see a “class photo” of the setup below, although the position and orientation of the radios was different during the actual recordings.

KCJJ

The first recording was at night, where we tuned to 1630 KCJJ in Iowa City, IA. This is effectively a 1KW clear channel; other than a few TIS stations, there’s not much else there on the east coast, and the signal is reliably weak to moderate but readable here on the east coast.
