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 Michael Bird,  John Figliozzi, and Jack Dully for the following tips:


Radio Six Pops Up Again on Shortwave (Radio World)

Radio Six International has not been a full-time shortwave broadcaster for some time. But after two recent live broadcasts on 6070 kHz prompted by the pandemic, it says it will continue monthly broadcasts at least for now.

WLW’s America’s Truckin’ Network To Refrain From Political Talk (Radio Insight)

iHeartMedia News/Talk 700 WLW Cincinnati has eliminated political talk from its overnight “America’s Truckin’ Network” show hosted by Steve Sommers.

The Cincinnati Enquirer reports that Sommers told listeners of the change on Monday morning’s show after multiple unspecified complaints.

In the on-air statement, Sommers blamed the change on a group of individuals who took offense with comments made by a caller a few weeks ago.[]

NPR Radio Ratings Collapse As Pandemic Ends Listeners’ Commutes (NPR)

Broadcast ratings for nearly all of NPR’s radio shows took a steep dive in major markets this spring, as the coronavirus pandemic kept many Americans from commuting to work and school. The network’s shows lost roughly a quarter of their audience between the second quarter of 2019 and the same months in 2020.

People who listened to NPR shows on the radio at home before the pandemic by and large still do. But many of those who listened on their commute have not rejoined from home. And that threatens to alter the terrain for NPR for years to come, said Lori Kaplan, the network’s senior director of audience insights.

“We anticipated these changes,” Kaplan said. “This kind of change was going to take place over the next decade. But the pandemic has shown us what our future is now.”

Commercial radio is experiencing, if anything, worse declines. But audience research commissioned by Kaplan indicates that NPR’s audience is disproportionately made up of professionals who are able to work from home and who are interested in doing so even after the pandemic subsides.[]

The Day That New York Had Two Noons, a Century After Losing 11 Days (Untapped New York)

New York’s history has included everything from transit strikes to riots over Shakespeare to immigration from nearly every country in the world. Yet, for much of this history, people didn’t always know the “correct” time or date. Until 1883, virtually every place in the country set local time according to the sun. According to Sam Roberts in his book Grand Central: How a Train Station Transformed America, “Typically, noon would be regularly signaled so people could synchronize their clocks and watches.” From dropping a ball down a flagpole in Manhattan to ringing a gong, settlements all across the country would alert people of noon. But as railroads spread throughout the country, it was nearly impossible to standardize the time.

“A passenger traveling from Portland, Maine, to Buffalo could arrive in Buffalo at 12:15 according to his own watch set by Portland time,” Roberts writes. “He might be met by a friend at the station whose watch indicated 11:40 Buffalo time. The Central clock said noon. The Lake Shore clock said it was only 11:25. At Pennsylvania Station in Jersey City, New Jersey, one clock displayed Philadelphia time and another New York time. When it was 12:12 in New York, it was 12:24 in Boston, 12:07 in Philadelphia, and 11:17 in Chicago.”[]

Canada’s shortwave time station, CHU, is moving

Press release from the National Research Council (NRC) of Canada:

Time to change your shortwave radio dial

After seventy years of broadcasting Canada’s official time, NRC’s shortwave station CHU will move the transmission frequency for the 7335 KHz transmitter to 7850 KHz. The change goes into effect on 01 January 2009 at 00:00 UTC.

CHU is a part of NRC’s system for disseminating official time throughout Canada, broadcasting 24 hours a day from a location approximately 15 km south-west of downtown Ottawa. Listeners hear tones to mark the seconds, voice to announce the time in French and English, and digital data to set computers.

The atomic clocks at CHU are part of the ensemble of clocks in the time and frequency research laboratories in Ottawa, at the National Research Council Canada. The NRC clocks are used in conjunction with clocks in the time laboratories of other countries to construct the internationally accepted scale of time, UTC (Coordinated Universal Time), which is now the reference for official time used by all countries. UTC is the modern implementation of Greenwich Mean Time.

“Coincidentally, this frequency change comes at a time when NRC is investing resources to refurbish the aging transmitters at CHU in order to provide clear, dependable shortwave services as part of NRC’s mandate to disseminate time to all Canadians.” said Raymond Pelletier, Technical Officer at the NRC-Institute for National Measurement Standards, who oversees the CHU facility. “The shortwave time service is especially beneficial for those in remote locations where there is limited access to internet and telephone communication. CHU also provides a back up against failure of other services.”

In April 2007, the International Telecommunications Union re-allocated the 7300-7350 KHz band from a fixed service to a broadcasting service. Since then, interference on the 7335 KHz frequency has come from many information broadcasters around the world.

CHU listeners in Canada and around the world who have for so long considered the 7335 KHz frequency exclusively for time signals, are very vocal about this interference. We have heard from amateur radio operators, watchmakers, astronomers, and navigators who use the tones and voice signals. As well, comments were received from those who use the carrier as a calibration source at a distance for their equipment.

To give notice to users, CHU will broadcast an announcement in both English and French. More information
