Radio Waves: Old Time Radio Book, AM to Digital, and Radio in Maui, and Nationwide Emergency Alert Test in October

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 Mike, David Iurescia, Rich Dalton, and Dennis Dura for the following tips:


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.

Japan’s Longest Day: August 15, 1945

Many thanks to SWLing Post contributor, Fred Waterer, who writes:

At Noon on August 15, 1945, Emporer Hirohito spoke to his nation by radio for the first time, ever. The intrigue surrounding the recording of his speech and the effort to get it on the air would be worthy of a Hollywood film. When word started getting out that the broadcast would be made, fanatics who wanted to keep fighting staged an attempted coup. An NHK (Japan Radio Corporation) engineer had a gun to his head as an officer attempted to hijack the station at 5am. His coolness under pressure saved his life. He also temporarily severed the line to the transmitter, just in case the officer changed his mind about killing him.

Meanwhile at the palace, the NHK recording engineers had recorded two versions of the speech. The recordings (and the engineers) were hidden overnight, as was the Emporer, in the labyrinth of the palace. Coup leaders searching for the disks to destroy them failed. Eventually troops loyal to the Emporer took control of the situation, with many of the coup plotters killing themselves. At noon, the recordings were in the NHK studios and were broadcast as scheduled.

The actual broadcast:

In 1967 a film about these events was made in Japan, called Japan’s Longest Day and starring the great Toshiro Mifune.

The recording scene:

Looks like quite a film!

Thank you for sharing this, Fred.

Can you help Bob identify this mystery signal?

Many thanks to SWLing Post contributor, Bob (K7ZB), who shares the following note and recording: 

Hi Thomas,

I recently started using an SDRplay RSP1A with their new software release SDRconnect.

Quite a nice piece of work and my first foray into SDR after 60 years of analog radio (K7ZB).

Today I was listening to WWV on 10MHz and it was being interfered with a strange type of digital signal that pretty much covered the band.

I finally tracked it down to 9.979MHz, recorded it and sent it to a friend who did a bit of audio analysis on it by expanding out the signal to look at individual bursts.

I certainly don’t recognize the modulation although it sounded like a form of CW in burst mode.

I am just curious if you have any insight on this signal or where I might go to find out more about it.

Thanks,

Bob

“Don’t throw out that radio in the basement after all”

“Don’t throw out that radio in the basement after all”. Well that got my attention.

With the wildfires in the North West Territories causing the evacuation of the Territorial Capital I received a daily email from the Canadian version of The Conversation with that subject line.

The article outlines the difficulty of getting information to thousands of Yellowknifers who have scattered to communities and cities in BC and Alberta, from Edmonton to Calgary and to remote campgrounds by the sides of major highways. Some are thousands of kilometers from home. At the same time Meta is in a dispute with the Federal Government and has blocked the posting of news articles of any kind on Facebook.

This has complicated things and left AM and FM radio as the key and sometimes only method of informing this diverse population. CBC Yellowknife has even relocated to Calgary.

It makes for interesting reading here:

Paul’s short recording of Marconi Radio International

Many thanks to SWLing Post contributor, Paul Jamet, who writes:

Hi Thomas,

I tried in vain to pick up Radio Marconi International … And I’m not the only one! I’ve used several SDR kiwis installed in Italy, and only one has enabled me to listen to this station, which has only a very weak transmitter.

Here’s the audio file below [RMI signing on at 18hOO UTC] and a snapshot of the screen of my PC (see above):

 

Kind regards.

KiwiSDR 2 on the horizon…

A number of SWLing Post readers have shared a link to this post by KiwiSDR creator John Seamons on the KiwiSDR forum. In it, he (somewhat reluctantly) describes a new version 2 of the KiwiSDR that is in the works.

Image source: KiwiSDR Forum

John writes:

I don’t like to announce something before it’s ready. But my hand is being forced.

So please consider this a pre-announcement. There are no guarantees.

The PCB and bill-of-materials (BOM) are finished and ready for prototype construction.

The problem is I don’t know WHO is going to build this or HOW. So I don’t know WHEN it might be available. And most importantly I don’t know what it might COST.

If YOU have specific ideas about these questions please email me. I’m especially interested in full-service manufacturing and distribution outside of China.

KiwiSDR 2 Goals:

Minimal changes. Fastest time-to-market with lowest possible risk. BUT since the PCB is going to be re-spun fix some of the known limitations that don’t add too much risk:

    • New RF front-end:
      •   Balanced input via balun transformer
      •   Digital attenuator (per the advisory group: pSemi PE4312, 0 – 31.5 dB, 0.5 dB steps)
      •   Gas discharge tube (GDT) across input in addition to TVS diodes
      •   Static drain resistors (100K) from input connections to ground
    • External ADC clock brought out on third SMA connector
      •   Self test loopback mode using a short cable between this SMA and antenna input
    • New GPS chip to replace current one which is now EOL
    • Reverse polarity protection (via P-FET) on 5V DC input
      •   TVS diode across 5V input

I have an email advisory group. Many, many other changes and additions were considered and deferred. They have been put onto a list for the future.

Additional info as things progress.

Thank you.

Readers: If you have suggestions for John regarding a manufacturing and distribution facility outside of China, please connect with him on the KiwiSDR forum.

In my opinion, the KiwiSDR has been the most accessible and effective web-based SDR platform out there. I’m looking forward to version 2 and hope it becomes a reality in the near future.
