Radio Nederland, DX Contests, and a Silver Spoon: Ronald is Seeking Answers from the Past

From Ronald W. Kenyon’s collection

Many thanks to SWLing Post contributor, Ronald, who writes:

I am 83 years old now. When I was actively DXing from the late 1950s through the mid-1960s, some stations, such as Radio Prague and Radio Nederland, and clubs such as the Japan Short Wave Club (JSWC) organized contests with prizes, usually special QSL cards.

In 1957, Radio Nederland ran a DX contest and offered a special QSL card. The JSWC offered a special QSL card to SWLers who received confirmation of their special 5th Anniversary broadcasts from eight stations between December 1956 and January 1957.  I reproduced the JSWC card and the Radio Nederland card in my book, QSL: How I Traveled the World and Never Left Home.

Perhaps on this occasion or another occasion, Radio Nederland ran a contest and offered
prizes.  I won one of these prizes, a silver-plated commemorative sugar scoop spoon made by “Schonenberg.”

I illustrated it on the colophon of my book.Googling “Schonenberg,” I couldn’t figure out where it was located. Some said the Netherlands, some said Canton Thurgau, Switzerland, and one source  (obviously wrong) said England.

“Wettig gedept” on the box is abbreviated Dutch for Wettig gedeponeerd “legally deposed,” which suggests “Trademark Registered” in English.  Thus, I conclude that the spoons are made in the Netherlands–logical for Radio Nederland to have its prizes manufactured in its own country!

Questions:

    1. When did this contest take place?
    2. What were the rules of the contest?
    3. How many Schonenberg spoons were offered as prizes?
    4. Were there other prizes?

Harry Truman’s Hallicrafters

Many thanks to SWLing Post contributor Robert, who shares the following:

Hi Thomas – I visited the President Truman Library today and noticed an interesting item in their Oval Office recreation. It appears that not only did Mr. Truman have the first television inside the Oval Office, he apparently also had a Hallicrafters model SX-28 right behind his desk.

One wonders what stations he would specifically listen to, and what type of antenna was installed at the White House for this radio?

Cheers,

Robert

Pressing Buttons. Twirling Knobs and Throwing Switches

By Bob Colegrove

Move along.  Nothing informative to read here, just the wandering of an idle mind scheming with meandering fingers on a keyboard.  On the other hand, if your curiosity can’t be controlled, consider that a significant amount of enjoyment in this hobby is the mere operation of the radio – seeing what all the buttons, knobs, and switches do, both separately and in combination.  It’s always been this way.  Beginning in the Amplifiozoic Epoch there was continual rotation of the knobs.  This occurred before the discovery of ganged capacitors, when each circuit had to be tuned independently to resonate at the proper frequency.  Otherwise, nothing.

It could be quite confounding for a non-radiofile trying to break into the sport.  Just getting some sound out of a two-knob radio could be a challenge.  My late mother solved this problem on all our radios by painting a dab of red nail polish at the points on the dial where each local station came in.

The Complexities of Shortwave

Later, with the humble entry-level shortwave “set” there was conundrum in the way the bandspread interacted with the main tuning control, and the curious effect of the BFO switch.  Even the venerable Hallicrafters Company, which catered to the hams and SWLs of the time, recognized the problem. They tried to solve this by prescribing a default setting in installation and operating procedures for model S-40 receiver, The Hallicrafters Company, Chicago, USA, p. 4, 1946:

“NOTE. – Some of the control markings are in RED. This is an added feature incorporated for the convenience of the listener who is not familiar with radio terminology as an aid in setting the controls most used for the reception of standard broadcast stations.”

That was the nice way of saying it.  After many years, I still chuckle to myself thinking of an old ham radio mentor of mine who insensitively explained that the purpose of these markings was for certain members of the household who could not otherwise make the radio work.  On my S-40B, the “convenience” markings are white dots.

Modern Radios

Modern radios have many buttons, which can work in different ways.  A short press will do one thing while a long press will do something else.  Some buttons do one thing with the radio turned off and another thing with the radio turned on.  On many radios you can lock the buttons and knobs, in which case they won’t do anything.  You must get it right.

Hidden Features

Today, the possibilities with all these variables are boundless, even beyond the control of the manufacturers who incorporate the complex TEF6686 30-pin IC chips in their designs.  Qodosen has set the bar high by making a plethora of user-adjustable functions available on the DX-286.  An uncommonly informative 40-page manual has been included with each radio and is highly recommended as an essential tool to assist with its operation.

In recent years, Tecsun has capitalized on this by incorporating “hidden features” in some of their models; that is, their operation and even their very existence are not revealed in the manual.  In computer gaming parlance, these features are called “Easter eggs” for which one must hunt.  Originally, the inclusion of hidden features may not have been intentional, but with the introduction of the PL-880 in 2013 they became a veritable sensation, as testified by the countless owner postings on the PL-880 Yahoo users’ group of that time.  A prize of unbounded esteem and self-satisfaction went to the intrepid listener who discovered and solved a hidden feature.  This interest went on for several months as Tecsun tweaked the firmware and the “features” migrated somewhat.  But unfortunately, a spoiler has been introduced.  Hidden feature data sheets are now packaged with current models.  In case you are missing any, here is a sampling.

SDR

The complexity of radio operation is compounded still further by the advent of SDR, wherein combinations of various hardware and software components result in a host of possibilities.  Features and their placement seem endless as they are distributed on multiple menus.  As my personal experience is limited to WebSDR, I leave the pursuit of this point to others.

Manual Power Generation

Finally, the inclusion of some elementary form of leverage and dexterity is present in some radios.  Isn’t the hand-powered crank on today’s emergency radio akin to the vintage treadle-operated transcription machine pictured at the beginning of this posting?  Perhaps we have come full circle.

Conclusion

Today’s radios are a sort of Rubik’s cube which can continually be manipulated to provide many hours of discovery and complement the listening and DXing experiences.  So, the next time you crawl underneath the headset and unconsciously tune to the object frequency, zero beat on the necessary sideband, and adjust the proper bandwidth and volume, reflect on all the time and practice it took you to develop this useful skill.

Vote to Preserve the Battle Harbour Marconi Towers

The Battle Harbour Marconi Towers, located on Labrador’s rugged coast, are the last of their kind in North America and possibly the world. Built in 1904, they played a pivotal role in early global communications, notably transmitting Admiral Robert Peary’s 1909 North Pole expedition announcement. However, over a century of harsh weather and the impacts of climate change have left them in disrepair, threatening their survival.

Many thanks to David Iurescia, who notes that The National Trust for Canada’s Next Great Save competition offers a chance to secure $50,000 for the restoration of this historic site. Public voting is open from March 31 to April 17, 2025.

If anyone deserves recognition as the first tourists to visit western Guatemala it would be the American John Lloyd Stephens and Englishman Frederick Catherwood. In the 1820s and 1830s, Stephens traveled extensively in Europe and the Middle East and published several books about his journeys. On one of those trips he met Catherwood, an accomplished artist who traveled around the Mediterranean making drawings of archaeological sites.

The pair decided to visit Central America after coming across accounts of ruins in the region by the Honduran explorer Juan Galindo. Their trip received official support when U.S. President Martin van Buren appointed Stephens as a special ambassador to Central America.  The two men wandered the region for several months in 1839-40 visiting known Mayan sites and rediscovering many others. Stephens wrote two books about their travels, Incidents of Travel in Central America, Chiapas and Yucatán and Incidents of Travel in Yucatán while Catherwood published a book of his drawings, Views of Ancient Monuments in Central America, Chiapas and Yucatan. All three books became immediate bestsellers.

Frederick Catherwood’s 1840 lithograph of the central plaza in Quetzaltenango, Guatemala. 

The three books introduced the Mayan civilization to the rest of the world for the first time, bringing new visitors to the region. Some came to do serious research. Others were just curious adventurers. But the numbers that came were small as only a few wealthy people had the time and money to journey to exotic places.

Then the 1960s brought a new kind of tourist – the hippie. Many young people in Europe and North America saw flaws in the materialism of their own societies and became interested in experiencing non-western cultures. The Mayan region of Guatemala was a perfect destination. It was exotic, relatively easy to get to, and cheap.

That qualification of cheap was especially important. The hippies weren’t big spenders staying in classy hotels and eating at pricey restaurants. They found rooms in basic hospedajes and ate everyday local food cooked by indigenous women at roadside comedores. In many ways that was better. The money went directly to local working people instead of to the wealthy owners of fancy establishments.

The 1960s and 1970s became the era of hippie tourism in Guatemala. Most of visitors went to the area around Lake Atitlán, drawn by the lake’s natural beauty and the region’s year-round springlike climate. The epicenter of it all was the little lakeshore village of Panajachel.

Clouds of War

To anyone wandering the shoreline of Lake Atitlán in the mid-1970s, Guatemala seemed to be a peaceful place. In reality, a guerilla war was raging just a hundred kilometers away. In 1954, a CIA-sponsored coup overthrew Guatemala’s elected government and ushered in a long period of repressive military regimes. With the military showing no signs of relinquishing power, around 1965 a few leftist activists went into the remote mountains of northern Huehuetenango and Quiché departments with hopes of repeating Fidel Castro’s success in Cuba.

By all appearances, this should have been a minor footnote in Guatemala’s history. The would-be revolutionaries, after all, were city people without the skills to survive in the remote mountain highlands. But they recruited a few Mayans to their movement and then a few more until the Mayans dominated the guerilla movement. Yet the Mayans were never guided by ideology. The guerilla movement was a way of fighting back against centuries of repression, discrimination, and poverty. As one observer put it, “They’re Communists because of their stomachs, not because of their heads.”

As the guerilla movement grew the combat zone gradually moved south and into other regions. And the war became less a political revolution than an ethnic conflict. The military was dominated by Spanish-speaking ladinos who knew nothing of Mayan culture or the Mayan languages. All Mayans were seen as potential enemies, as was anyone who attempted to improve the Mayans’ lives. That lead to the formation of military-run death squads which targeted small town mayors, teachers, social workers, church leaders, and anyone else who dared to speak up. By 1981 over two hundred non-combatants were being kidnapped, killed, and dumped by the side of the road every month.

In 1976 the Lake Atitlán region had been seen as a peaceful place. A few years later the combination of active military death squads in the villages along the lake and a widening guerilla war elsewhere had put an end to that image. The era of hippie tourism in Guatemala was over. Continue reading

When I started DXing in 1971, and for several decades afterwards, the most widely logged Guatemalan shortwave station by DXers was Radio Cultural on 3300 kHz. It was also known as TGNA, the call letters of that 90-meter-band frequency. The medium wave outlet on 730 kHz was TGN. The station also used 5955 kHz and 9505 kHz, but those frequencies were always harder to hear because of interference from more powerful international broadcasters.

Back then this Evangelical broadcaster was owned and operated by the Central American Mission of Dallas, Texas, but only received a portion of its funding from the CAM. Additional funding came from local donations in Guatemala and another important source was selling time to American Evangelical preachers to air their prerecorded English language religious programs. These programs were broadcast late at night, when propagation into North America and Europe was best, and were always preceded by an English station identification. That made it an easier log for DXers who didn’t understand Spanish.

TGNA was the station I most wanted to visit when I arrived in Guatemala City in June 1983. But Guatemala DX Club members informed me that the station had been temporarily closed down because of “philosophical disagreements” with the government. They were off the air and would remain so for several weeks. I made four more visits to Guatemala City over the next year but somehow never found the time to visit the station. It wasn’t until my visit in December 1987 that I finally stepped inside their front door. That visit became the subject of the first article I wrote for Monitoring Times magazine in June 1988.

Wayne Berger, station manager and chief engineer, and missionary Bob Rice gave us a very long tour of the station. Wayne and Bob had built or rebuilt most of the station’s technical equipment and even some of the infrastructure. On the day we arrived they were welding a broken door back on its hinges. Wayne had built the 3300 kHz transmitter, shown in the next picture, out of spare parts.

At the time of my visit, TGNA had two pennants. The larger one was mostly reserved for local listeners. The smaller one was sometimes included with QSLs to lucky DXers.

But neither of those compared with these traditional handmade weavings given by listeners for the station’s 37th anniversary in August, 1987. (I just wish my color photos had survived.)

Easter in Guatemala

Of all the things I’ve seen in my travels, the Easter processions of Guatemala certainly rank near the top. I am fortunate to have been in Guatemala twice for the holiday, in 1982 and 1984, and I plan a return trip in the next few years. Processions take place all over Guatemala during Easter week, but the most elaborate take place on Easter Thursday and Good Friday in Guatemala City and, especially, in Antigua, the old capital twenty kilometers to the west. There are several processions both days in each city and each procession takes several hours. Continue reading

Don Moore’s Photo Album:  Guatemala (Part Two) – Guatemala City

Guatemala City, the country’s capital, is the political, economic, and social hub of the country. The next largest city, Quetzaltenango, is less than a fifth as big. Guatemala City also forms a pivot point dividing the country. The departments to the west and the Verapaz region to the north are heavily indigenous. Quiché department is named after the country’s largest Mayan group. The Pacific departments to the south and those to the east are mostly populated by Spanish-speaking ladinos, which is what mestizos of mixed Spanish and indigenous heritage are called in Guatemala. It’s the ladinos and Guatemala’s small European-descended upper class who rule the country. Although the Mayans and a few smaller groups represent half of Guatemala’s population, the country has never had an indigenous president. That’s not where the power lies.

While I was working in Honduras, all of my visits to Guatemala included a few days in Guatemala City. It wouldn’t make anyone’s lists of Latin America’s best capitals but I always enjoyed returning. It felt like a city. Honduras’ capital of Tegucigalpa felt like an overgrown small town.

Guatemala City had a very diverse radio scene with stations programming for all the segments of the population. You could tune in everything from Guatemalan marimba music to English-language rock to Spanish-language romantic pop to Mexican ranchera to Argentine tango. There was even a commercial classical music station on medium wave. Several of the stations – Radio Nuevo Mundo comes to mind – had very professional news departments. And three of Guatemala City’s radio stations broadcast on shortwave.

But for me the best part of visiting Guatemala City wasn’t the shopping or the museums or even visiting the radio stations. It was getting to see my friends in the Guatemala DX Club.

Guatemala DX Club

In early 1983 I connected with the Guatemala DX Club through Radio Netherlands’ Spanish language DX program, Radio Enlace.  I first got together with them on my second visit to Guatemala in June 1983 and then made a point of visiting them every time I came to the city. The GDXC had several dozen members, mostly in Guatemala City. Only about eight or ten regularly participated in club events and those are the ones I met. The club had occasional meetings, sometimes organized visits to radio stations, and published an annual newsletter. They also produced a weekly fifteen-minute DX program on La Voz de Guatemala.

This photo was taken during my last visit in December 1987. In the back row are Carlos Zipfel Valencia, Jorge Luis Álvarez, and Edgar Oliva. Me and Ralf Gruner are seated in front.

Edgar was an official monitor for Deutsche Welle and had a beautiful huge Grundig receiver that the station had gifted to him. It had been sent by diplomatic pouch to the West German embassy where he had picked it up in person.

Carlos’ father, Carlos Zipfel y García, was a well-known Guatemalan writer but Carlos was more interested in the spoken word of radio. After getting a communications degree he received professional training through programs run by Radio Netherlands and Deutsche Welle and pursued a career in broadcast journalism and management. At different times he’s served as a producer for La Voz de Guatemala, director of Radio Universidad de San Carlos, and in various roles for several public and non-government organizations such as the Federation of Guatemalan Radio Schools.

I’ve always liked the GDXC pennant. It was intentionally designed to point left so that it would easily fit on the wall between the usual right-pointing radio station pennants. Only a DXer would think of doing that! The design features Guatemala’s national bird, the quetzal, which is known for its long tail feathers.

La Voz de Guatemala

During my first visit with the club, Carlos used his day off to take me to visit the radio station he was working at plus several more medium wave and FM stations. He already had many professional contacts so I had some very memorable station tours. Carlos also used his press credentials to get me a private tour of part of the Palacio Verde, or presidential palace.

The station I was most interested in seeing was the official government radio station, TGW La Voz de Guatemala, also sometimes called Radio Nacional de Guatemala. I had a very long visit there as Carlos, of course, had connections. It was he who produced the club’s weekly DX program on TGW.

The Estudio Maya was a spacious room where live marimba music concerts were broadcast each week. The station even had its own handmade marimba. The use of the name Estudio Maya is interesting. Guatemala embraces the historical image and importance of the Mayans while at the same time ignoring the present-day Mayan population. Half of Guatemala’s population speak Mayan languages but the national radio station only broadcast in Spanish.

Visiting radio stations usually includes collecting souvenirs and TGW didn’t disappoint. Here are several items from the station’s 50th anniversary in 1980. I also picked up several QSLs signed and sealed not just by the head station producer but also by Carlos on behalf of the Guatemala DX Club.

TGW La Voz de Guatemala, 640 kHz, as recorded in Guatemala City in June 1983:

A Musical Interlude

The marimba is Guatemala’s national musical instrument and if you ever heard one of Guatemala’s shortwave stations you surely heard the music. Like the banjo, the marimba is an instrument that always sounds happy. It’s impossible to play a sad song on one. The instrument is like a xylophone but is made of wood. Although smaller ones do exist, a true marimba requires seven musicians playing in unison. A live concert is an amazing sight. Continue reading
