Former Downriver music educator pens book on history of old-time radio (News-Herald)

Brian Rogers is an adventurer of sorts. He’s what you might call a renaissance man. Born in Buffalo, New York, Rogers has been a part of the fabric of the Detroit area since his family moved here in 1943.

Since then he’s been a music educator, choir and band director, speech therapist, paralegal and a freelance writer.

You could say that everything Rogers has pursued, both vocational and otherwise, has centered on the art of communication. And the affable educator and author certainly honed his literary skills through the revised edition of his new book “Adventures in Old Time Radio.”

It is 146 pages and 50 chapters of brief excerpts and articles on the evolution of radio from its inception in the 1920s through 1960.

Rogers, a longtime Allen Park resident who now lives in Dearborn with his wife, Clara, was inspired to compile the book out of his love for, and activity in, the shortwave radio community and as a columnist for the Great Lakes Monitor. [Continue reading…]

Crawford Will Flip an Alabama AM to All-Digital (Radio World)

Crawford Broadcasting is going to give all-digital HD Radio a try on an AM station in Alabama.

On Sept. 1 the Christian broadcaster will flip WYDE in Birmingham to the MA3 mode; only listeners with HD Radio receivers will be able to hear the AM signal after that, though the same content will be available on two local FMs. Two other AMs in the country currently operate in all-digital.

“We’d like to give all-digital AM a try and see how it performs,” said Director of Engineering Cris Alexander. “The timing is right for us.”

The FCC approved the use of all-digital AM in 2020. WYDE airs at 1260 kHz with a 5 kW signal by day and 41 Watts at night.

“That particular station is ideally situated for an all-digital move,” said Alexander, who also is technical editor of Radio World Engineering Extra. [Continue reading…]

Radio and Maui: A Failure To Communicate? (Jacobs Media Strategies)

The morbidly funny video from the 1960’s classic “Cool Hand Luke” became a popular meme well before there was an Internet. You see it pop up when organizations or people on the same team (or in a relationship) suffer a serious breakdown in communication. Suffice it to say, this is a common condition.

When we look at what happened in Maui, we have a human tragedy that is off the charts. By the time this is all set and done, we will likely be looking at hundreds of people dead, upwards of $6 billion in funds to restore the damage, and incalculable pain and suffering. When weather disasters happen, widescale damage is often unavoidable. And the wildfires that swept through Lahaina fit that definition. But could the damage in human, financial, and property costs have been mitigated or decreased?

Maui is a place where many of us have been on vacation. Looking at the photos, it is unimaginable just how extensive the damage is. And in the aftermath, there are questions – lots of them – about what went wrong. [Continue reading…]

Hawaii Puts AM Radio to Work on Maui

The state has acquired four portable emergency advisory radio systems

Emergency officials in Hawaii will use AM broadcast equipment to help communicate with the public during the ongoing wildfire recovery efforts on Maui.

The State of Hawaii Emergency Management Agency has purchased four RadioSTAT portable emergency advisory stations from Information Station Specialists in Michigan, which also makes specialized systems for applications such as Traveler’s Information Stations and Highway Advisory Radio.

The Wireline Competition Bureau of the Federal Communications Commission last week granted the state an emergency authorization to use the stations immediately at four locations including a checkpoint and police and fire stations. They can be used on 1620, 1650, 1670 or 1700 kHz. [Continue reading…]

FEMA and FCC Plan Nationwide Emergency Alert Test for Oct. 4, 2023 (FEMA)

Test Messages Will be Sent to All TVs, Radios and Cell Phones

WASHINGTON — FEMA, in coordination with the Federal Communications Commission (FCC), will conduct a nationwide test of the Emergency Alert System (EAS) and Wireless Emergency Alerts (WEA) this fall.

The national test will consist of two portions, testing WEA and EAS capabilities. Both tests are scheduled to begin at approximately 2:20 p.m. ET on Wednesday, Oct. 4.

The WEA portion of the test will be directed to all consumer cell phones. This will be the third nationwide test, but the second test to all cellular devices. The test message will display in either English or in Spanish, depending on the language settings of the wireless handset.

The EAS portion of the test will be sent to radios and televisions. This will be the seventh nationwide EAS test.

FEMA and the FCC are coordinating with EAS participants, wireless providers, emergency managers and other stakeholders in preparation for this national test to minimize confusion and to maximize the public safety value of the test.

The purpose of the Oct. 4 test is to ensure that the systems continue to be effective means of warning the public about emergencies, particularly those on the national level. In case the Oct. 4 test is postponed due to widespread severe weather or other significant events, the back-up testing date is Oct. 11.

The WEA portion of the test will be initiated using FEMA’s Integrated Public Alert and Warning System (IPAWS), a centralized internet-based system administered by FEMA that enables authorities to send authenticated emergency messages to the public through multiple communications networks. The WEA test will be administered via a code sent to cell phones.

This year the EAS message will be disseminated as a Common Alerting Protocol (CAP) message via the Integrated Public Alert and Warning System-Open Platform for Emergency Networks (IPAWS-OPEN).

All wireless phones should receive the message only once. The following can be expected from the nationwide WEA test:

  • Beginning at approximately 2:20 p.m. ET, cell towers will broadcast the test for approximately 30 minutes. During this time, WEA-compatible wireless phones that are switched on, within range of an active cell tower, and whose wireless provider participates in WEA, should be capable of receiving the test message.
  • For consumers, the message that appears on their phones will read: “THIS IS A TEST of the National Wireless Emergency Alert System. No action is needed.”
  • Phones with the main menu set to Spanish will display: “ESTA ES UNA PRUEBA del Sistema Nacional de Alerta de Emergencia. No se necesita acción.”

WEA alerts are created and sent by authorized federal, state, local, tribal and territorial government agencies through IPAWS to participating wireless providers, which deliver the alerts to compatible handsets in geo-targeted areas. To help ensure that these alerts are accessible to the entire public, including people with disabilities, the alerts are accompanied by a unique tone and vibration.

Important information about the EAS test:

  • The EAS portion of the test is scheduled to last approximately one minute and will be conducted with the participation of radio and television broadcasters, cable systems, satellite radio and television providers and wireline video providers.
  • The test message will be similar to the regular monthly EAS test messages with which the public is familiar. It will state: “This is a nationwide test of the Emergency Alert System, issued by the Federal Emergency Management Agency, covering the United States from 14:20 to 14:50 hours ET. This is only a test. No action is required by the public.

FCC Authorizes AM radio stations to operate using all-digital broadcast signals

Many thanks to SWLing Post contributor, Paul Evans, Mike S, and a number of others who have contacted me regarding the FCC’s Authorization of All-Digital AM Radio. Below, you’ll find the FCC press release:


For Immediate Release

FCC AUTHORIZES ALL-DIGITAL AM RADIO

Action Will Improve Listening Experience and Provide Consumers with Enhanced
Services

WASHINGTON, October 27, 2020—The Federal Communications Commission today
adopted a Report and Order that allows AM radio stations to operate using all-digital broadcast
signals. AM broadcasters will be able to voluntarily choose whether and when to convert to
all-digital operation from their current analog or hybrid analog/digital signals.

All-digital broadcasting offers AM listeners significantly improved audio quality and more
reliable coverage over a wider listenable area than analog or hybrid digital broadcasts. It also
allows broadcasters to provide additional services to the public, such as song title and artist
information. These enhancements will enable AM broadcasters to better compete in today’s
media marketplace.

Today’s Order establishes technical rules to protect existing AM broadcast stations from
interference. In addition, stations converting to all-digital operation will be required to notify
the Commission and the public 30 days in advance of their transition. These stations must
provide at least one free over-the-air digital programming stream that is comparable to or better in audio quality than a standard analog broadcast. They also must continue to participate in the Emergency Alert System. The Order envisions that AM broadcasters will decide whether to convert to all-digital operation based on the conditions in their respective markets.

Action by the Commission October 27, 2020 by Report and Order (FCC 20-154). Chairman
Pai, Commissioners O’Rielly, Carr, Rosenworcel, and Starks approving. Chairman Pai, and
Commissioner Rosenworcel issuing separate statements.

MB Docket Nos. 19-311, 13-249

Radio Waves: First Microprocessors, Ocean FM, SWL Interviews, and NPR’s take on All-Digital AM

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’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Marty, Martin Butera, and the Radio Survivor for the following tips:

The Surprising Story of the First Microprocessors (IEEE Spectrum)

Transistors, the electronic amplifiers and switches found at the heart of everything from pocket radios to warehouse-size supercomputers, were invented in 1947. Early devices were of a type called bipolar transistors, which are still in use. By the 1960s, engineers had figured out how to combine multiple bipolar transistors into single integrated circuits. But because of the complex structure of these transistors, an integrated circuit could contain only a small number of them. So although a minicomputer built from bipolar integrated circuits was much smaller than earlier computers, it still required multiple boards with hundreds of chips.[]

Ocean FM Was Fire: How Local Radio Done Right Can Heat A Cabin | Radio Schmaltz (Part-Time Audiofile)

[…]The cabin on a rocky peninsula in Northwest Ireland might not have had all the letters for its Scrabble set or a microwave, but it did have another marvel of 20th century technology. It was a little CB/AM/FM radio crouching behind a box of matches on top of a kitchen cabinet.

I decided to put the switch on FM and started swirling the dial. As soon as I heard a lilting woman’s voice underneath a sheet of static, I began carrying it around the tiny room while adjusting the rabbit ears.

Now the signal was as clear as the peat-rich water was brown, a farmer was being interviewed about the economic downturn. It was a quick piece — just some brogue-ish assurances that one doesn’t choose agriculture for an easy life. Then came a trio playing an Irish ballad, and then came North West Hospice Bingo: a bingo game that allows listeners from across the broadcast range of Ocean FM’s two regional frequencies to play bingo, including the residents of the hospice.

I’d bundle up for walks outside where the wind was loud, blustery, and sacred. The ocean crashed against the rocks in a way I never conceived as being real outside of movies. But when I was inside, the radio might as well have been a Soviet relic with only a volume control and no tuner because I simply couldn’t touch that dial. I learned the schedule quickly, timing walks and firewood runs so that I’d be back in time for Country Jamboree, a boy-girl-boy-girl style line-up of Irish and American country tunes.

As I’d stand by the wood-stove, taking off my cold wet socks to put on the toasted, at time singed socks that I’d been roasting, I felt the fulfillment of the promise of radio. I could hear Fessenden making history with the first radio broadcast of music, Oh Holy Night transmitted on a rocky coast on Christmas Eve of 1906 and heard by ships at sea.[]

Coffee and Radio Listen

Coffee and Radio Listen is an investigation of Brazilian radio listener, by Martin Butera.

How they began listening to radio, the local or international stations that influenced them, the interests they have when tuning to a station, the languages they like to listen to, if they send listeners reports and collect QSLs, their antennas and receivers, and all aspects related to the radio listen both in shortwave and in other bands and modes.

Each month they will have in this blog, an exclusive interview with a Brazilian radio listen. At the end of this project, a free downloadable e-book will be available, which contains all the interviews and statistical references.

Every month there will be a new interview, this month of March launch month we start with 2 interviews

Martin is Argentinian, born in the city of Buenos Aires capital. He currently lives in Brasília DF, capital of Brazil. He is also a journalist, documentary maker and founding member of Radio Atomika 106.1 MHz (Buenos Aires, Argentina).

NPR Supports All-Digital on AM, With Caveats (Radio World)

National Public Radio “generally supports” allowing stations to transition, if they wish, to all-digital AM transmission using HD Radio in the United States. But it believes the commission needs to go further on how it would handle interference complaints from neighboring analog stations in the band.

About 80 AM public radio stations are affiliated with NPR or receive operational funding from the Corporation for Public Broadcasting, including WNYC(AM) in New York City.

NPR says it has significant interest in any measures to help AM broadcasters better serve the public by improving the listening experience.

“Facilitating the expansion of HD Radio and its additional functionality for program and public safety information and services would serve the public interest, provided the transition to all-digital HD Radio operation does not cause harmful interference,” NPR wrote in comments filed with the FCC this week.

“As it has in the past, NPR supports the expansion of HD Radio, but not at the expense of current analog AM service.”[…]

Many thanks to SWLing Post contributor, Dan Robinson, who shares the following note posted by Paul McClane at Radio World:

For those who want to sound off to the FCC about using all-digital on the AM band — either “fer it” or “agin it” —- the comment deadlines now are set.

Comments are due March 9, reply comments are due April 6.

As RW has reported, the FCC recently released a notice of proposed rulemaking to establish rules governing all-digital broadcasting by AM radio stations in the United States.

Read the NPRM here. The NPRM number is 19-123.

FCC proposes allowing AM stations to go all-digital

(Source: Radio Insight)

The FCC approved today the adoption of a rulemaking allowing AM stations to transition to all-digital operation.

Hubbard Radio’s “The Gamut” 820 WWFD Frederick MD has been operating in all digital mode since July 16, 2018 in collaboration with HD Radio owner Xperi. The new rulemaking will allow AM stations to go all-digital and establish operating parameters for doing so.

The FCC today also is opening a comment period on the removal of the programming duplication rule adopted in 1992. The rule limits AM or FM stations from airing more than 25% of total hours in an average broadcast week of duplicative programming. The rule applies to commercial stations in the same service (AM or FM) with substantial contour overlap that are commonlyowned or subject to a time brokerage agreement.[…]

FCC to consider allowing AM broadcasters to transition to digital

(Source: Radio World)

All-Digital on the AM Band? The FCC Might Allow It Soon

AM radio station operators in the United States may soon have the option of switching their transmissions to all-digital.

It’s not a done deal; but the concept is about to take a step closer to reality, because the Federal Communications Commission will consider a proposal at its next meeting that would start a process. It will take comments on whether to allow AM band licensees to make the switch if they want.

Ben Downs, VP/GM of Bryan Broadcasting in Texas, petitioned the FCC in March to initiate a proceeding to authorize the all-digital mode of HD Radio.

Allowing stations to use all-digital transmission is an idea that some broadcasters feel could give business-challenged AM stations in the United States new life or at least another option. Turning off their analog signals would mean that most existing receivers could no longer pick up that signal; but many AM broadcasters are currently heard on FM translator simulcasts now. And adding the all-digital AM option could open up new possibilities for them as the number of digital receivers in the marketplace continues to grow.

[…]Chairman Ajit Pai described the proposal in a blog post Monday: “Just as the FCC is trying to keep pace with changes in the market, so are AM radio operators, and the commission wants to give them as much flexibility as possible to compete in the digital age,” Pai wrote.[…]

The Radio World article mentions WWFD in Frederick, MD–a station that has been broadcasting AM digital for over a year. We posted a note about this last year and I even included a short recording/video with reception when traveling through the area.
