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 Paul, Dennis Dura, Dan Van Hoy, Alokesh Gupta,  and the Southgate ARC for the following tips:


Atrocious but efficient: How ranchers used barbed wire to make phone calls (Texas Standard)

A barbed wire telephone call didn’t sound great but could quickly warn others about something such as a wildfire.

Historian J. Evetts Haley wrote that, in its time, the old XIT Ranch up in the Texas Panhandle was “probably the largest fenced range in the world.” He recalled that its barbed wire enclosed over 3 million acres of land. At the north end alone, the fence ran for 162 miles. The unique enclosure helped keep in enormous cattle herds, keep out rustlers, and also gave rise to the creative use of a new technology: the telephone.

I’ll come back to the XIT in a moment, but first, consider these smattering of reports from that era. In 1897, The Electrical Review, reported that “on a ranch in California, telephone communication had been established between the various camps . . . by means of barbed wire fences.” The article says the novel use of the phone was a great success and was being used in Texas as well. That same year, the New England Journal of Agriculture was impressed that two Kansas farmers, living a mile apart, had attached fine telephone instruments to the barbed wire fence that connects their places and established easy communication. From the Butte Intermountain in 1902 we see this notice: “Fort Benton’s latest development is a barbed wire telephone communication.” The article points out that people of the range were not all that happy with barbed wire, which they thought was an “evil” that had arrived with the railroad, but they had decided to look at the practical side of its existence and use it to create a telephone exchange that would connect all the ranches to Fort Benton.

FCC Says No to Appeal for a New AM in L.A. (Radio World)

Schwab Multimedia has lost an appeal to the Federal Communications Commission in a case involving a planned AM station near Los Angeles for which it had a construction permit.

This is a “tolling” case, one that involves the FCC construction clock. The history is complex — the FCC’s summary is 2,500 words long, not counting many extended footnotes — but the upshot is that KWIF in Culver City was never built and, barring further developments, apparently will not be. Its call sign has now been deleted.

Levine/Schwab Partnership, which does business as Schwab Multimedia, had applied in 2004 to build a new AM station in the Los Angeles area. It eventually secured a CP in 2016 for the station at 1500 kHz. [Continue reading at Radio World…]

Rob notes several radios in Fleksnes Fataliteter

Many thanks to SWLing Post contributor, Rob Gray, who writes:

Happy Holidays Thomas!

As I see those that like to raise awareness of radios in TV and movies, here’s my submission. A Swedish friend of mine sent this to me and it’s a little rough to follow without knowing the language, but there are certainly radios in the episode!
73,
Rob

The radios get going around 3:53 and 4:35, 11:15, etc.

As a side note, I’m happy to see the chess board properly oriented, I’ve frequently seen the board rotated 90 degrees from proper in programs, and even on display in Russian museums!

Thank you so much for sharing this, Rob!

Video: Stock Radiwow D-808 vs. DeBock 7.5 inch Loopstick model

Many thanks to SWLing Post contributor, Gary DeBock, who shares the following notes and video:

The 7.5 inch (19cm) loopstick Radiwow R-108 model “smokes” the stock R-108 model in this video demonstration of receiving daytime DX fringe station 550-KARI in Blaine, WA (5 kW at 150 miles). The modification uses the same enhanced loopstick as described in the XHDATA D-808 “Supercharging” article, and is reasonably easy to complete (although some experience is recommended)

Video: Story of Gibraltar Broadcasting Corporation’s move to a new broadcasting house

Many thanks to SWLing Post contributor, Tracy Wood, who writes:

While searching the revamped Gibraltar Broadcasting Corporation’s website (gbc.gi) I came across a recent documentary that might be of some interest. It’s titled “GBC: The Move”. The GBC website states it’s a “story about the move from our home of the last 41 years to the ‘new’ Broadcasting House on Rosia Road, a project 4 years in the making. Featuring interviews with staff, the build, history and insight to the huge undertaking that is moving whilst staying ‘”on air’.”

The documentary includes photos of the former 1458kHz top-loaded medium-wave originally located at the Bastion downtown, before it’s relocation to a site above Engineer Road with a much larger “top-hat.” The program covers aspects of both the radio and TV services. (GBC offers three radio services – Radio Gibraltar, Radio Gibraltar Plus FM, Radio Gibraltar Plus AM. The Plus services include two hours of Spanish Monday-Friday and run in parallel except when the AM service covers Gibraltar Parliament sessions.
