AM Radio History: 80th Anniversary of the “Havana Treaty,”

Many thanks to SWLing Post contributor, Bob Colegrove, who writes:

Hi Thomas,

I came across this article on Wikipedia. It is a few days late, but thought it might be of interest to others. The link is

https://en.wikipedia.org/wiki/North_American_Regional_Broadcasting_Agreement.

Briefly, this past Monday, was the 80th anniversary of the implementation of the “Havana Treaty,” which was actually signed on December 13, 1937, and finally implemented 80 years ago on March 29, 1941. It provided for reorganization of the “AM” medium wave band into frequency allocations for clear channel, regional and local stations.

AM radio was the Internet of its day. The invention of the telegraph notwithstanding, radio provided widespread, instant communication, albeit one way, to a vast population reaching hundreds of miles from the transmission source. It extended to the most rural parts of the country adding “A battery” and “B battery” to the lexicon.

The initial licensing process had been done with very little planning and forethought using 96 channels between 550 and 1500 kHz. The reorganization was the culmination of the need for some order to reduce mutual station interference and provide more reliable service to listeners. It involved frequency changes for about 1000 stations in several countries. March 29, 1941 was informally known as “moving day.”

The Wikipedia article details the changes made at that time and goes on to describe subsequent expansions of the AM broadcast band.

Fascinating! Thank you for sharing this bit of radio history with us, Bob!

China bans BBC World News from broadcasting (BBC News)

China has banned BBC World News from broadcasting in the country, its television and radio regulator announced on Thursday.

China has criticised the BBC for its reporting on coronavirus and the persecution of ethnic minority Uighurs.

The BBC said it was “disappointed” by the decision.

It follows British media regulator Ofcom revoking state broadcaster China Global Television Network’s (CGTN) licence to broadcast in the UK.

Separately, the broadcaster Radio Television Hong Kong (RTHK) said it would stop relaying BBC World Service programming in the region, prompting condemnation from the BBC.

China’s State Film, TV and Radio Administration said that BBC World News reports about China were found to “seriously violate” broadcast guidelines, including “the requirement that news should be truthful and fair” and not “harm China’s national interests”.

It said that the BBC’s application to air for another year would not be accepted.

The BBC said in a statement: “We are disappointed that the Chinese authorities have decided to take this course of action. The BBC is the world’s most trusted international news broadcaster and reports on stories from around the world fairly, impartially and without fear or favour.”[]

In Our Time: The Invention of Radio (BBC Sounds)

Melvyn Bragg and his guests discuss the invention of radio. In the early 1860s the Scottish physicist James Clerk Maxwell derived four equations which together describe the behaviour of electricity and magnetism. They predicted the existence of a previously unknown phenomenon: electromagnetic waves. These waves were first observed in the early 1880s, and over the next two decades a succession of scientists and engineers built increasingly elaborate devices to produce and detect them. Eventually this gave birth to a new technology: radio. The Italian Guglielmo Marconi is commonly described as the father of radio – but many other figures were involved in its development, and it was not him but a Canadian, Reginald Fessenden, who first succeeded in transmitting speech over the airwaves.

World Radio Day 2021: Radio creates diversity and connects people (RADIOZENTRALE GmbH)

World Radio Day 2021: Radio creates diversity and connects people

World Radio Day will be announced by UNESCO for the tenth time on February 13th and once again refers to how important radio is for society and why it connects people.

Time to celebrate: UNESCO has proclaimed World Radio Day for the tenth time. In Germany, radio has been the everyday companion of people for a hundred years and, more than ever, radio is the medium of the hour. So this jubilee round provides many good reasons to pause and ask what radio means for each individual, society and the world. Radio itself does not take a break, it is on the air – every day and around the clock. Radio informs, entertains and offers a variety of programs, opinions and content. As a matter of course – and yet so indispensable – radio, both large and small, is the vital voice of people and for people.

At the global level, radio remains the most widely consumed medium

The world is changing rapidly. Social and political processes are becoming more dynamic due to new technologies, the communication network is getting faster and bigger and the challenges are becoming more important. In these processes, radio not only offers diversity, classification and orientation, but is also an integral part of opinion-forming because it is the platform for democratic discourse. This unique ability to reach a wide audience means radio can shape a society through diversity and is the place for those who want to speak up.

100 years of radio in Germany

In Germany, the medium for the ears and the head cinema is celebrating its centenary this year. The innovative strength of the medium and the trust base with listeners that has grown over the decades make it possible for radio to be the medium of the hour more than ever. It is the last mass medium and at the same time can digitally reach everyone with the entire range of offers. Radio is at eye level with people – both in terms of content and technology. Because just as society and people’s everyday lives have changed dramatically, so too have listening habits and content. What remains, however, is the great art of putting complex topics into understandable words and giving diversity a voice.

“Today we are experiencing that the world is changing rapidly. We face major challenges when I think of climate change, the current corona pandemic or the debates on racism, for example. The task of radio here is to inform and classify. To make the soft tones heard and to reflect the diversity of opinions, ”says Grit Leithäuser, Managing Director of Radiozentrale. “But the most important thing is to act at eye level with the listeners. This grown connection and mutual trust are something for both sides that one should be aware of and that it has to be preserved every day. Then, in a hundred years, radio will be the medium for people who listen on whatever technical route, in order to learn from one another and to live diversity. ”

World Radio Day was first proclaimed by UNESCO in 2012 and this year it has the motto: “New World, New Radio”. At the suggestion of Spain, the General Conference of UNESCO initiated World Radio Day in memory of the founding of United Nations Radio on February 13, 1946. The aim of the day is to make the public and the media more aware of the importance of radio, to the decision-makers Encourage information to be established and made accessible through the radio.

Further information on World Radio Day can be found at: https://en.unesco.org/commemorations/worldradioday

The generic initiative Radiozentrale sees itself as a common platform for public and private radio stations as well as generic companies in the radio industry. The radio center has set itself the goal of positioning the medium of radio and providing comprehensive information about the (advertising) medium of radio. More information: www.radiozentrale.de

How radio became a cult in its early years in Germany (DW)

A century ago, the age of radio began in Germany. Cultural broadcasts made radio popular before the Nazis appropriated it for their propaganda.

On December 22, 1920, the first radio broadcast in Germany hit the airwaves. “Attention, attention — this is Königs Wusterhausen on radio wave 2700.” This was how a Christmas concert by the employees of the German Reichspost was announced. Featuring a clarinet, reed organ, string instruments and piano, they played in the broadcasting building of the city of Königs Wusterhausen.

Modest sound quality

Transmission quality was poor: static and crackling accompanied the musical performance. Only official agents of the German Reichspost could listen to this transmission since in accordance with the Treaty of Versailles, private citizens in Germany were forbidden from listening to radio signals.

Society on the move

Nonetheless, radio in Germany was born. Society at the time of the Weimar Republic was in transition. Painters were no longer merely depicting the natural worlds — Cubism, Dadaism and abstract art were unearthing new dimensions of the imagination that had no direct reference to reality. Musicians and composers were creating hitherto unheard-of sounds with jazz and twelve-tone techniques joining familiar rhythms and keys. Writers and poets were creating parallel plots and stories. Consumer products were being mass-produced. Aviation was connecting people over thousands of kilometers — and radio was booming.

The first official radio entertainment program in Germany was broadcast on October 29, 1923. The Allies had by then lifted the ban on listening to radio waves. The fact that we even have an acoustic record of it today is due to a coincidence: a few months after it was broadcast, the program was re-enacted and preserved on disc.

Broadcasting with a mission

Meanwhile, inflation was soaring in Germany. Poverty and misery were rampant, especially in the big cities. “Radio was welcomed in Germany like a liberating miracle, especially at a time of intense emotional and economic hardship,” Hans Bredow, considered the “father” of German radio, said at the time.

Like many radio pioneers of the Weimar years, Bredow had lofty ambitions to widen national perspectives in his position as Radio Commissioner to the German Reich’s Postal Minister. This new technology was to signal an end to the age of ignorance and prejudice.

In December 1923, there were a total of 467 listeners. One year later, there were already one million listeners within the Reich’s entire territory. And in 1932, there were more than four million paying radio subscribers — and at least as many non-paying listeners. The daily broadcasting time also increased steadily. In 1923, it was 60 minutes; by 1932, there were already 15 hours of radio programs every day.

Entertainment for the masses

It was the new possibilities of simultaneous acoustic reporting that captivated the “Radioten, ” a derogatory term that was used for radio lovers at the time. An extraordinary media event at that time, the radio achieved its exciting effect through its immediacy and “live” character. And it gave birth to a genre unknown until then: the radio play.

Meanwhile, heated debates abounded about the negative effects of radio on listeners, culture and politics. Many intellectuals and artists distanced themselves from the new medium. Among them was the Austrian composer Arnold Schönberg. “Broadcast media caters to the majority. At any time of the day or night, people are served a feast for the ears without which they apparently can no longer live today. I assert the right of the minority against this delirium for entertainment: one must also be able to broadcast what is necessary, and not only the trivial.”[Continue reading full story at DW…]

Earthlings and astronauts chat away, via ham radio (Phys.org)

The International Space Station cost more than $100 billion. A ham radio set can be had for a few hundred bucks.

Perhaps that explains, in part, the appeal of having one of humankind’s greatest scientific inventions communicate with Earth via technology that’s more than 100 years old. But perhaps there’s a simpler explanation for why astronauts and ham radio operators have been talking, and talking, for years.

NASA astronaut Doug Wheelock was just a few weeks into his six-month mission at the space station when feelings of isolation began to set in.

Wheelock would be separated from loved ones, save for communication via an internet phone, email or social media. At times, the stress and tension of serving as the station’s commander could be intense.

One night, as he looked out a window at the Earth below, he remembered the space station’s ham radio. He figured he’d turn it on—see if anyone was listening.

“Any station, any station, this is the International Space Station,” Wheelock said.

A flood of voices jumbled out of the airwaves.

Astronauts aboard the space station often speak to students via ham radio, which can also be used in emergencies, but those are scheduled appearances. Some, like Wheelock, spend their limited free time making contact with amateur radio operators around the world.

“It allowed me to … just reach out to humanity down there,” said Wheelock, who interacted with many operators, known as “hams,” during that stay at the space station in 2010. “It became my emotional, and a really visceral, connection to the planet.”

The first amateur radio transmission from space dates to 1983, when astronaut Owen Garriott took to the airwaves from the Space Shuttle Columbia. Garriott was a licensed ham who, back on Earth, had used his home equipment in Houston to chat with his father in Oklahoma.

Garriott and fellow astronaut Tony England pushed NASA to allow amateur radio equipment aboard shuttle flights.

“We thought it would be a good encouragement for young people to get interested in science and engineering if they could experience this,” said England, who was the second astronaut to use ham radio in space.[]

Special call signs in Belgium during the second lockdown period (Southgate ARC)

Belgian amateurs activate the following special event callsigns to remind everyone of Covid-19 restrictions and express gratefulness to medical personnel:
OS2HOPE, OT5ALIVE, OT4CARE, OR20STAYHOME, OT6SAFE, OP19MSF, OQ5BECLEVER, OR6LIFE, OO4UZLEUVEN and OT2CARE.

Due to the recent stricter COVID-19 measures, many radio amateurs will be forced to spend most of the following weeks at home again. Many are obliged to telework. Teleworking is definitely becoming the new standard for several employees. COVID-19 has accelerated teleworking for almost all companies.

At the request of the Royal Union of Belgian Radio Amateurs (UBA), the BIPT has decided to once again grant permission to apply for customised special call signs. The exceptional conditions apply to special call signs with an encouraging meaning.

These appropriate special call signs may be used at the home address of radio amateurs. The conditions are the same as during the first lockdown in spring.
Radio amateurs are allowed to re-request the special call sign obtained during the first lockdown.

Operation until January 31, 2021.

Many thanks to SWLing Post contributors Ted Lipien, Josh Shepperd, Ronnie Smith, and Gary Butterworth,  for the following tips:


Ted Lipien returns to U.S. international broadcasting as head of RFE/RL December 18, 2020 (USAGM)

WASHINGTON, D.C. — Michael Pack, CEO of the U.S. Agency for Global Media (USAGM), announced today that veteran civil servant Ted Lipien is returning to U.S. international broadcasting as CEO and President of Radio Free Europe/Radio Liberty (RFE/RL).

“Few people have a greater understanding than Ted of the multifaceted operation and mission of U.S. international broadcasting,” said CEO Pack. “Ted is an ardent and captivating advocate of democracy who will excel at sharing America’s founding principles and ideals with the world.”

“When I was a teenager in Communist Poland, I would listen to Radio Free Europe to find out what the government was not telling me,” said Mr. Lipien. “It had an enormous impact on my life, and on the lives of millions of others. I’m honored, and humbled, to be entrusted with helping this storied organization continue to break the hold of censorship and give voice to the silenced.”

Mr. Lipien has dedicated virtually his entire career to U.S. international broadcasting. He joined Voice of America (VOA) in 1973 and served as the network’s Polish Service Chief for 12 years, from 1981 to 1993, including the Solidarity labor union’s struggle for human rights and democracy in Soviet-communist-ruled Poland. From 1993 to 2003, he served as the Broadcasting Board of Governors’ Eurasia Marketing Specialist and Director, first in Munich and, later, in Prague. Mr. Lipien then rejoined VOA, serving as Eurasia Division Director from 2003 to 2005 and Acting Associate Director from 2005 to 2006. He has interviewed a number of eminent public figures, including Cardinal Karol Wojty?a (Pope John Paul II), Lech Wa??sa, George H.W. Bush, Zbigniew Brzezinski, and Czes?aw Mi?osz.

In 2008, after leaving the federal service, Mr. Lipien founded Free Media Online, a non-governmental organization committed to supporting free media worldwide. His pro-media freedom work has been noted in a variety of national publications, including the New York Times, Wall Street Journal, and Washington Post. His articles have appeared in National Review, Washington Times, and Washington Examiner. Mr. Lipien earned his bachelor’s degree in international relations with distinction from George Washington University.

RFE/RL, headquartered in Prague, is a non-federal network funded by the United States Congress through USAGM. Daisy Sindelar, who had been serving as Acting President of RFE/RL since June 2020, is returning to her former role as the network’s Vice President and Editor-in-Chief.[]

On the Radio: The Library’s Special Research Collections to become home to the American Radio Archives (UC Santa Barbara)

The American Radio Archives, one of the world’s largest and most valuable collections of radio broadcasting will soon become part of the UC Santa Barbara Library’s Department of Special Collections.

Established by the Thousand Oaks Library Foundation (TOLF) in 1984, the archive is one of the first in the state and includes original recordings of Winston Churchill, as well as broadcast photographs, radio and television scripts, books and film dated as early as 1922.

“It is critical that such a wonderfully curated collection documenting the golden age of radio is preserved and accessible, said Thousand Oaks Mayor Claudia Bill-de la Peña. “UCSB has one of the largest collections of performing arts records, sound recordings and broadcast recordings on the West Coast as well as a state-of-the-art audio laboratory, making it our first choice and a natural fit for the American Radio Archives.”

The collection was established in 1984 and grew significantly with the purchase in 1987 of radio memorabilia from the estate of Rudy Valleé, one of the nation’s most popular singing bandleaders and personalities. Valleé documented his career, which took off in the1920s, through an extensive array of journals, photographs and original pieces of advertising.

The prominence of the Valleé collection attracted numerous celebrities and radio historians from around the world who gravitated toward the American Radio Archives. Among them were such luminaries as Norman Lear, Carl Reiner, Ron Howard, Ray Bradbury, Norman Corwin, Edward Asner, Walter Cronkite, Janet Waldo, Candice Bergen and William Shatner.

When Norman Corwin — dubbed America’s poet laureate of radio — donated his career files in 1990, it further increased esteem for the archives and generated significant interest among radio aficionados. As a result, many noteworthy collections were donated to TOLF, including, among others, those of radio station KNX-CBS; radio actor and radio historian Frank Bresee, who hosted “The Golden Days of Radio”; comedian Red Skelton; Carlton Morse, the creator of the long-running radio soap opera “One Man’s Family”; radio and television writers Milton and Barbara Merlin; and Allin Slate, a pioneer of the sports talk show format on KABC radio in Los Angeles.[]

Oregon ARRL VEC Testing Group Offers Testing from the Comfort of Your Car (ARRL News)

The coronavirus pandemic has made life difficult for everyone. On the plus side, however, it’s prompted creative solutions to work around the various roadblocks the pandemic has imposed. Volunteer Examiners in Grant County, Oregon, affiliated with the ARRL Volunteer Examiner Coordinator (VEC) put their heads together to overcome the adversity and hold a safe and secure exam session. Current health regulations in Oregon precluded both indoor and outdoor gatherings. Nonetheless, the Grant County Amateur Radio Club, the local ARES Group, and the Grant County Emergency Radio Infrastructure Coalition (ERIC) combined forces to offer five candidates the chance to obtain their first license or to upgrade their existing license, all from the comfort of their vehicles.

“Many amateur radio clubs have experimented with exams via the internet,” said Steve Fletcher, K7AA, who is the ARES Emergency Coordinator for Grant County. “In eastern Oregon, with the cooperation of the County Roads Department, we chose to hold a ‘drive-up’ exam session on Saturday, December 12. Under the circumstances, we used four ARRL VEs for the exam instead of the required three.” Wheeler County ARES loaned Stuart Bottom, K7FG, to help as the third required Amateur Extra-class Volunteer Examiner.

Fletcher reports three new Technician licensees and two new General-class radio amateurs resulted from the session.

Required ARRL VEC forms contained pre-printed data — including the FCC Registration Number (FRN) — were given to the candidates on a clipboard. Each candidate took the exam in the front seat of their own vehicle. Cell phones, papers, and anything not required for the exam were removed.

“Everyone dressed warmly, and most candidates had their heaters running,” Fletcher reported. A camper owned by Ronda Metler, KB5LAX, and a communications van owned by Fletcher served as sites to check results and sign forms.

The Grant County Roads Department loaned its parking area for the exam session.[]

On International Migrants Day, VOA Expands Broadcasts to Displaced Communities in Africa (VOA Press Release)

As the world observes International Migrants Day on December 18, Voice of America continues to enhance its operations to serve the growing refugee populations in Africa. UNHCR, the UN Refugee Agency, reports that, in just the past few weeks, 50,000 Ethiopian refugees have joined the world’s 80 million forcibly displaced people, including more than 18 million in sub-Saharan Africa.

Recognizing the deteriorating conditions in northern Ethiopia’s Tigray region in recent weeks, VOA rapidly added existing Tigrigna-language radio broadcasts to existing VOA FM radio stations in the Libyan cities of Tripoli and Misrata. These newscasts reach not only the newly displaced civilians, but also Eritreans in both cities who arrived prior to the current exodus and still have ties to the crisis-affected area. Newly created “micro sites” deliver digital content in TigrignaAmharic, Afan Oromo and English from VOA regional reporting teams.

In Kakuma, Kenya, site of one of the world’s oldest refugee camps, VOA launched a new FM station to provide both refugees and the local community with news, music, and educational content in English, Swahili, and Somali. For the Dadaab refugee complex near Kenya’s border with Somalia, a new VOA station offers local residents and refugees a mix of VOA English and Somali language content that airs in Somalia and Djibouti.

“VOA is committed to providing vital news and information to underserved populations worldwide, including refugees and other forcibly displaced persons,” said VOA Director Robert Reilly. “In particular, as the only international broadcaster with a presence in Kakuma, VOA serves as a critical lifeline for individuals in this region with access to few other reliable media resources.”

VOA’s efforts to reach at-risk refugee populations expanded exponentially in 2017 in south Asia and Latin America. VOA’s Bangla language service began broadcasting in Rohingya to reach refugees in Kutupalong, the world’s largest refugee camp. Nearly one million ethnic Rohingya, who fled persecution in neighboring Myanmar, inhabit the site. When Venezuelans began to flee President Nicolás Maduro’s regime, the VOA Spanish language service significantly increased its coverage of this unfolding crisis for audiences all across the region.

VOA FM Frequencies

Existing in Libya: Tripoli (106.6 MHz); Misrata (99.1 MHz)

New in Kenya: Kakuma (99.9 MHz); Dadaab (106.7 MHz)

Ham radio operators honor legacy of Mars Hill company (Citizen Times)

During the 1950’s and ’60’s, when the Hammarlund Manufacturing Company had a factory just west of Mars Hill College, the town could have been considered a world center of advanced electronic technology. With a company motto of “Quality Without Compromise,” almost 90% of American WWII wartime military electronic equipment employed Hammarlund capacitors. They also built U.S. Navy search radar installed on aircraft carriers, battleships and cruisers.

Hammarlund was one of the three leading brands of radio communications equipment at the time, along with Hallicrafters and Collins Radio. These three companies dominated in providing state of the art electronics equipment to the U.S. military, large and small corporations, and to private individuals who had the means and taste to own the very best.

Hammarlund Radio initially operated out of New York City starting in 1910, in the early days of radio. They began consolidating all of their operations in Mars Hill in 1951, in a newly constructed facility that spread out to over 100,000 square foot on Hammarlund Drive — now named Hickory Drive. The site employed hundreds from around the area and their work lives on today. []

FM Radio From Scratch Using An Arduino (Hackaday)

Building radio receivers from scratch is still a popular project since it can be done largely with off-the-shelf discrete components and a wire long enough for the bands that the radio will receive. That’s good enough for AM radio, anyway, but you’ll need to try this DIY FM receiver if you want to listen to something more culturally relevant.

Receiving frequency-modulated radio waves is typically more difficult than their amplitude-modulated cousins because the circuitry necessary to demodulate an FM signal needs a frequency-to-voltage conversion that isn’t necessary with AM. For this build, [hesam.moshiri] uses a TEA5767 FM chip because of its ability to communicate over I2C. He also integrated a 3W amplifier into this build, and everything is controlled by an Arduino including a small LCD screen which displays the current tuned frequency. With the addition of a small 5V power supply, it’s a tidy and compact build as well.[]

2016 Report Confirmed Problem of Political Bias At Voice of America (USAGM Watch)

by Dan Robinson

Trump USAGM CEO Michael Pack Was Attacked For Attempts to Focus on Problem

It was May of 2016 and Amanda Bennett was only a few weeks into what would become a nearly four year stint as director of the Voice of America, among the “plum” jobs in Washington, D.C.

Bennett was just getting her feet wet, and at the time was dependent on a group of longtime embedded VOA managers that she would at one point describe as a “fantastic leadership team.”

She had received fair warning, from former VOA employees and extensive reporting by the independent watchdog website BBG and USAGM Watch, of disturbing issues at VOA, located in what has long been one of the most dysfunctional of federal agencies.

Some VOA journalists were using their taxpayer-funded positions to engage in self-promotion and campaign for political causes, a fact little known to most Americans. VOA’s website and digital operations were plagued by failures in breaking news coverage, and inaccuracies in content.

Both VOA and what was then called the Broadcasting Board of Governors (BBG) were increasingly seen by U.S. lawmakers as moribund. A Republican-led and eventually bipartisan effort in Congress proposed major restructuring – there was little patience left on Capitol Hill where the agency was increasingly considered to be “broken,” “rudderless,” and “worthless.” President Obama signed the reform legislation in December 2016 to create a powerful agency CEO position and to make the BBG Board purely advisory.[]

ARISS Slow Scan TV event (Southgate ARC)

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS) for late December. This will be a special SSTV event to celebrate the 20th anniversary of ARISS.

The event is scheduled to begin on December 24 and continue through December 31.

Dates are subject to change due to ISS operational adjustments.

The Geminids – a reminder (Southgate ARC)

The Geminids are a prolific meteor shower caused by the object 3200 Phaethon, which is thought to be a Palladian asteroid with a “rock comet” orbit. This would make the Geminids, together with the Quadrantids, the only major meteor showers not originating from a comet.

They are the biggest meteor shower of the year, and normally occur between 4 December – 17 December.

The peak is expected on 14 December.

Expect FM “pings” and hopefully interesting dx opportunities.

“QSL: How I Traveled the World and Never Left Home” by Ronald W. Kenyon

A few weeks ago, I was contacted by author Ronald W. Kenyon who has written non-fiction books covering a variety of subjects, but primarily collections of essays and albums of photography.

He was very proud to announce that his latest book, QSL: How I Traveled the World and Never Left Home, focuses on his pursuit of DX during his youth.

Kenyon is a radio archivist at heart.  He has carefully preserved QSL cards that he received between 1956 and 1961–a time period many of us consider the zenith of international broadcasting and DXing.

Kenyon’s book presents color reproductions of over 100 vintage QSL cards—most displaying both front and back—issued by 89 shortwave stations in 75 countries. For the uninitiated, he includes an introduction that acquaints with shortwave radio listening, submitting listener reports, and obtaining QSL cards. Radio enthusiasts will be familiar with these topics, but this addition is an important one since we often forget that we’ve a niche pursuit and for many of his readers, this will be their first introduction.

Kenyon sent me a pre-sales sample of his book. It’s what I’d call a “coffee table” paperback. The format is 8.5 x 8.5 inches which gives each QSL image proper page space to be presented. The color reproduction and print in this publication is excellent.

I’ve thoroughly enjoyed taking in Kenyon’s book at a very leisurely pace. It’s divided into three main sections:

  • Section One of his book is a gallery of 107 vintage QSL cards from radio stations in 78 countries.
  • Section Two features SWL and ham radio cards.
  • Section Three features seasonal greeting cards sent to listeners by radio broadcasters from nine countries.

There’s even an appendix featuring, “A Letter from Antarctica,” which recounts how Kenyon was linked to a British meteorologist at a base in Antarctica via a radio station in Montevideo, Uruguay of all places. A fabulous example of how radio–especially in the late 50s and early 60s–was a fabulous medium for connecting listeners across vast distances.

I’m a nostalgic fellow–especially during the Thanksgiving and Holiday season. I’ll admit: this wonderful, simple bit of radio nostalgia is just what the doctor ordered as we celebrate the season. We all can relate to and enjoy Kenyon’s gallery of radio nostalgia and history. Indeed, my hope is that his book will encourage others to document their radio journey as well.

Being a limited print, full-color, 150 page book, the price will be $35 US. However, the author has offered 10% off his book if ordered before December 31, 2020. That will lower the price to $31.50 US via Amazon.com or £23.95 via Amazon.co.uk.

If you enjoy browsing QSL cards like I do, you’ll love QSL: How I Traveled the World and Never Left Home. Certainly, a fabulous gift idea for the radio enthusiast in your world.
