Historic Bell Labs Horn Antenna At Risk, Holmdel Citizens Group Says (Patch.com)

Citizens for Informed Land Use is against a proposal before the Planning Board to reclassify the former Nokia site for redevelopment.

HOLMDEL, NJ — Citizens for Informed Land Use, Preserve Holmdel and others are rallying to preserve the Bell Labs Horn Antenna, which they say is threatened if the 43-acre site it stands on is reclassified for residential development.

The property at 791 Holmdel Road is home to the Bell Labs Horn Antenna, once used by Bell Labs scientists Dr. Robert Wilson, who still lives in the township, and Dr. Arno Penzias, to study microwave radiation from beyond the Milky Way, the organization says.

The site is also described by the group “as the highest point in Monmouth County, providing remarkable views of Raritan Bay and Manhattan.”

The scientists’ “research confirmed evidence of the Big Bang Theory as the origin of the universe and earned both men a Nobel Prize in Physics in 1978,” the land use group said in a news release.

But on Nov. 22, the Township Committee approved a resolution directing the Planning Board to study whether the former Nokia site in the Crawford Hill section of Holmdel – the site of the Horn Antenna – should be reclassified as an “area in need of redevelopment.” [Continue reading…]

New Jersey’s Disturbing Monolith Secrete: The Rise and Fall of Tuckerton Tower (YouTube)

In Tuckerton, NJ, a massive cement monolith sits out of place, and upon closer inspection, out of time. You see, this gigantic block was once the base of the tallest structure in North America and the second tallest in the world after the Eiffel Tower. Built in 1912, the Tuckerton tower stood at 825 feet and was the first and most potent transatlantic broadcasting tower ever, but here’s the twist, although it was on US soil, it was entirely built by and belonged to Germany.

Why the tallest tower on earth collapsed | The Warsaw Radio Mast (YouTube)

The Warsaw Radio Mast (Polish: Maszt radiowy w Konstantynowie) was a radio mast located near G?bin, Poland, and the world’s tallest structure at 646.38 metres (2,120.7 ft) from 1974 until its collapse on 8 August 1991.

Designed by Jan Polak, and one of the last radio masts built under Communist rule, the mast was conceived for height and ability to broadcast the “propaganda of the successes” to remote areas such as Antarctica. It was the third tallest structure ever built, being surpassed as the tallest by the Burj Khalifa tower in the United Arab Emirates in 2009 and Merdeka 118 tower in Malaysia in 2022. Designed by Jan Polak, its construction started in July 1970, was completed on 18 May 1974, and its transmitter entered regular service on 22 July of that year. The opening of the mast was met with extensive celebration and news coverage by the Polish Film Chronicle.

ABC Radio Australia’s 83 years of broadcasting to the world (ABC)

This is the story of one of the ABC’s best kept secrets.

ABC Radio Australia was never intended to be a great secret. It was just the nature of the service that few Australians knew about it. When I hosted its breakfast program for nine years, I could count on one hand the number of people who knew what I was talking about when I told them I worked for RA.

Most people mistakenly thought it was the same thing as Radio National. I would have to explain, yet again, that this was our version of the BBC World Service, a worldwide broadcaster.

RA was founded at the start of the World War II by prime minister Robert Menzies as an antidote to the disinformation being broadcast by Australia’s new enemies, Germany and Russia. The idea of Australia Calling, as the service was initially named, was to provide an antidote to this propaganda, to counter that aerial bilge with factual, balanced and fair reportage.

So with a small team of English, Spanish, Dutch and French broadcasters, a minuscule budget and some tiny transmitters in antiquated shacks in Victoria and New South Wales, Australia joined the short-wave age in December 1939. [Continue reading…]

Boost for AM Broadcasting in NZ’s Northland Region (Content Technology)

Situated on the northwest tip of New Zealand’s north island, and home to the historically significant Waitangi Treaty Grounds, the Northland region is to receive a funding boost to strengthen its AM broadcasting infrastructure.

New Zealand’s Minister of Broadcasting and Media, Willie Jackson, and Minister for Emergency Management, Kieran McAnulty, have announced a NZD$1.48 million package to fund the repair and replacement of three transmission masts in Northland to ensure AM radio can stay on air in the region.

“This funding will secure the reinstatement of the Waipapakauri mast, which services Far North communities, and replace the masts at ?taika and ?haeawai which are on their last legs,” Willie Jackson said. “This will ensure that Northland communities retain their access to AM transmission in areas that are not serviced by FM frequencies.

“RNZ has already completed work to reinstate the Waipapakauri mast, which went back on air today.”

Minister for Emergency Management Kieran McAnulty said radio is a critical information channel to help reach New Zealanders in an emergency.

“When emergencies happen, the National Emergency Management Agency (NEMA) and local Civil Defence Groups work with the media to issue warnings and other critical information. We rely on radio as our number one emergency info channel as it is the most resilient and widely available form of public communication.

“Northland is especially reliant on AM radio due to its remote and rugged terrain, its exposure to hazards like tsunamis, and limited access to cellular service and other information sources,” Kieran McAnulty said. [Continue reading…]

Taliban Blocks Afghan Broadcasts By VOA, Radio Free Europe/Radio Liberty (All Access)

The TALIBAN has shut down several VOICE OF AMERICA RADIO ASHNA FM repeaters and has blocked RADIO FREE EUROPE/RADIO LIBERTY’s Afghan service RADIO AZADI, alleging that the U.S.-backed outlets are violating Afghani press laws and journalistic principles.

A statement from the VOA said that the move, which it noted broke a multiyear contract between the stations and the Afghan government, “is a blow to the large audience that turns to RADIO ASHNA for uncensored news and information. VOA broadcasts provided the people of AFGHANISTAN uncensored perspectives and hope. They gave ordinary Afghans a voice through call-in programs and discussion shows about subjects censored by domestic media. On VOA programs, topics ranged from the increasing isolation of AFGHANISTAN’s current government and the second-class status of women and girls as a result of the TALIBAN’s policies to the persistent economic failures that have diminished the quality of life in AFGHANISTAN since the TALIBAN takeover.”

“Many programs were anchored by women,” said Acting VOA Director YOLANDA LÓPEZ. “Removing VOA from the domestic airwaves will not silence us. It will only increase the importance of serving the captive audience inside AFGHANISTAN.”

The statement noted that the VOA reaches 7.3 million adults per week in the country, with almost half of those listening on broadcast radio; the service can also be heard via satellite TV, shortwave, AM, streaming, and social media and is “actively exploring additional ways to provide our content and fulfill our mission of serving our audience in AFGHANISTAN.” [Continue reading…]

Taliban hit Voice of America with broadcast ban (DW)

US-funded Voice of America said Taliban authorities pointed to “complaints” about their programing. Radio Free Europe was also banned by the Islamist regime.

Voice of America (VOA) and the AP press agency reported that Taliban authorities banned radio broadcasting from VOA and Radio Free Europe/Radio Liberty (RFE/RL) in Afghanistan from Thursday.

According to VOA, the Taliban authorities cited “complaints they have received about programming content” as reason for the ban.

However, there were no further details provided about the alleged complaints, VOA shared in a press statement.

Both VOA and RFE are funded by the US government, but “operate with journalistic independence and aim to provide comprehensive, balanced coverage,” the statement continued.

Whether or not the ban will be extended to other international broadcasters in Afghanistan remains unclear at this point.

In March, some parts of DW’s Afghan programing were stopped from being rebroadcast by Afghan partners, and BBC news bulletins in Pashto, Persian and Uzbek also taken off air.

Taliban say VOA and RFE ‘failed to show professionalism’
Afghanistan’s Foreign Ministry spokesman Abdul Qahar Balkhi told AP his country had laws regulating the media and any network that was “repeatedly contravening” them would be banned.

“VOA and Azadi Radio (Radio Liberty) failed to adhere to these laws, were found as repeat offenders, failed to show professionalism and were therefore shut down,” he said.

The Taliban regime has been cracking down on press freedom in the country by imposing restrictions on media and journalists since seizing power last year. [Continue reading…]

Giuseppe upcycles and improves a homebrew MW antenna

Many thanks to SWLing Post contributor, Giuseppe Morlè (IZ0GZW), who shares the following:

Dear Thomas and Friends of SWLing Post …

This is Giuseppe Morlè. As always, I try recycling what I have and improving upon antennas I’ve built in the past. This is one way we radio lovers can experiment. Many years ago, I made an antenna only for medium waves; by adding a circuit, I can now listen to short waves.

I took advantage of a small frame that I recovered from an old commercial FM / AM stereo receiver by removing its coils for medium waves and I wound around it only two coils sufficient to have a frequency range from 3.5 to 18 MHz.

I remember that the antenna in question also receives medium waves as it was born.

I chose this small frame because I wanted everything to be small in order to carry this compact antenna everywhere.

Unlike my other projects for SW and MW, which have a cable that carries the SW signal to the receiver, this time I used the induction that is created around one end of the loop, which I spiraled to get inside the stylus of my Tecsun PL-660 and which then transfers the signal to the receiver.

I did some tests on my balcony the day after a strong storm and I noticed that the propagation was absent but I still wanted to make sure that everything was working.

[Note that you can translate this video into your language via YouTube’s automatic subtitles. Click here to learn how to do this.]

I will keep you updated on other tests on more favorable days of propagation … I still invite you to follow me on my Youtube channel.

I wish everyone a good listening …
73. Giuseppe Morlè iz0gzw.

Many thanks, Giuseppe. I, for one, love all of your homebrewed and recycled antennas. This one is no exception! What a fun project. I love how you use what you have and aren’t afraid to experiment! Thank you for sharing.

Colombia’s life-saving pop song (BBC Sounds)

It is 2010 and Colombian Colonel Jose Espejo has a problem. Not only is the Farc increasing its kidnapping activity, targeting police and military hostages, but many of the soldiers already in captivity – some kept in barbed-wire cages and held isolation in for over a decade – are losing hope of ever being rescued.

Colombia’s dense jungle and mountainous terrain mean rescue missions can take months to plan, especially because Farc guerrillas are known to shoot all hostages dead at the first hint of a raid. Colonel Espejo knew that in order for future missions to succeed, he would need to warn the captives that help was coming so they could be ready to make a break for it when the army arrived. But how do you get a message across to military hostages without tipping off their captors and placing them in even greater danger?

The unexpected solution – hide the message in a pop song with an interlude in Morse code that the military hostages could decipher. Soldiers learned Morse code in basic training, and it was unlikely that the Farc, who were not military trained, would know it. This is the tale of Better Days, a pop song with a secret Morse code message that became an actual lifesaver.

FCC Commissioner Advocates for Preservation of AM Radio (Radio World)

At the NAFB Convention, Simington said AM radio is an “indispensable resource”

FCC Commissioner Nathan Simington met with members of the National Association of Farm Broadcasting during their 79th annual convention on Nov. 16. In his remarks, Simington emphasized the importance of AM radio and outlined the steps needed to ensure its future in a changing market.

Simington began his remarks with a more personal anecdote. He said he grew up on a farm in Saskatchewan, Canada, where “besides the trade papers, there was no media institution more trusted to inform us about all we needed to know than AM radio.”

“AM radio was for us then, and is for the more than three million farmers across the U.S. now, an indispensable resource,” he said.

Simington said AM radio is the “essential spine” of the Emergency Alert System and “lets you know what’s happening not just globally, but locally — from school closures and traffic delays to city council and county management meetings and high school sports games.”

He comments on the growing populations that view AM radio as a “dead” and outdated technology, and why he believes that to be a falsity. [Continue reading…]

Don Moore’s Photo Album: Santa Bárbara, Honduras

by Don Moore

I first set foot in Latin America in January 1982 when I arrived in Tegucigalpa to begin three months of Peace Corps training. Three months later I moved to my Honduran home, the town of Santa Bárbara in the western mountains. For the next two years I worked as a teacher and resource person at the Escuela Normal Mixta de Santa Bárbara, a specialized high school that trained its students to teach primary school.

Santa Bárbara had a shortwave station, La Voz del Junco on 6075 kHz but it was rarely reported because it broadcast irregularly and was usually blocked by big international broadcasters when it was on the air. I had never heard it but I met Miguel Hasbun, the owner-manager, on my first visit to Santa Bárbara when he picked me up hitchhiking north of town. He told me that the shortwave transmitter had been broken down for a while but that he was going to fix it ‘soon’. Over the next year I kept inquiring about the shortwave and he finally did fix it. After that the station broadcast irregularly for the next year or so, mostly in the morning. I served as volunteer veri-signer and issued around fifteen QSLs. I even issued one to myself.

Santa Bárbara had one other radio station, Ondas del Ulúa on 1140 kHz medium wave (later 1150 kHz). They also announced 4770 kHz shortwave in their canned IDs and station staff assured me they would be adding shortwave “soon”. It never did happen but the WRTH did list the frequency as future plans for several years.

Audio:

Ondas del Ulúa 1982 sign-off announcement mentioning 4770 kHz.

The department of Santa Bárbara had one other radio station, Radio Luz y Vida on 1600 and 3250 kHz in the town of San Luis. The founder, manager, and veri-signer for Radio Luz y Vida was a missionary from Oklahoma named Don Moore. Needless to say, this caused a lot of confusion in the DX world as some people assumed he and I were the same person. On the map, San Luis is only about thirty kilometers from Santa Bárbara but getting there involved a five-hour journey on two buses. I only went once and the other Don Moore was out of town, so I never met him. I did meet two nurses who were working at the mission’s health clinic.

The small tower on the left was the corner of what had been an army post but was being used as a regional prison in the early 1980s. I once went there every day for a week to supervise student-teachers doing adult literacy classes for the inmates. It was not a pleasant place to be.

The International Radio Report’s 35th Anniversary!

Many thanks to SWLing Post contributor, Sheldon Harvey–creator, co-host and co-producer of the International Radio Report–who shares the following announcement:

Almost impossible for me to believe it, but Sunday’s upcoming edition of the International Radio Report on CKUT-FM in Montreal will be our 35th anniversary edition of the program. The first edition of the program aired on Thursday, November 19, 1987, our old time slot. That week in 1987 CKUT was also born, going on the air on 90.3 FM, 7 days a week, 24 hours a day.

International Radio Report is one of only a couple of programs to have been continually on the CKUT schedule since the beginning. Our hosts have changed from time to time over the years, as did our time slot, moving from Thursday afternoons at 2:30 PM Eastern to Sunday mornings at 10:30 AM Eastern.

I’d like to thank everyone who has been a part of the program over the 35 years; the various hosts, the numerous guests, and the support of CKUT for standing behind us and providing us with an outlet to bring our program to the listeners, not just here in Montreal but, literally, around the world.

And, to the listeners, a big thank you to everyone who tunes in, whether Sundays on the radio, through online streaming, downloading the program, or tuning in through our YouTube channel. We thank those who have taken the time to submit stories and material for the program. It’s a great help.

Whether you’ve been with us since the early days, or whether you’ve discovered us and come on-board recently, without an audience and your support, we wouldn’t be here. And a very special thanks to those of you who have supported our program and CKUT over the years through the annual CKUT Funding Drive. It costs money to run a radio station. It certainly doesn’t all happen for free! Our listeners have been most generous over the years, making our 30-minute program one of the most successful programs on CKUT at bringing in funds to support the cause.

So, we hope you will tune in, by whatever means you tune in, on Sunday, November 20th to help us celebrate as we mark our 35th anniversary of the International Radio Report on CKUT 90.3 FM in Montreal.

Introduction

When I discovered DXing over fifty years ago I also discovered the world. Through my ears I traveled to other countries and explored other cultures. But DXing has also literally taken me places. My early interest in Latin American DXing developed into a broader interest in Latin America. That led to me joining the Peace Corps after college and working three years in Honduras. That experience furthered my interest in Latin America and I have continued to travel in the region whenever possible. For me DXing and travel were always intertwined. I’m one of a handful of hobbyists who took DXing beyond just listening and went knocking on broadcasters’ doors to visit the distant stations I heard. My ex-wife dubbed this ‘door-to-door DXing.’

To date I’ve visited over 150 radio stations in thirteen countries. A few were medium-wave or FM only, but I was always most interested in visiting broadcasters that used shortwave, either at the time of my visit or a few years before. As my station visits were primarily made in the 1980s and 1990s, almost all of the stations are long-gone from the shortwave bands. However, many are still around on medium wave and FM and often also via streaming on the Internet. As much as I miss the magic of shortwave I know that these stations reach more listeners today via streaming than they ever did with their low-powered shortwave transmitters. Honestly, I sometimes enjoy tuning them in without the fading and static of shortwave. But the memories of what shortwave once was are still there.

Photos also bring back memories. I took dozens of pictures on my station visits and enjoy scrolling through them now and then. You may have seen some of them. Many of my photos were printed with articles I wrote for various DX publications and I’ve done a few slide-shows at DX get-togethers over the years.

In this series of columns I want to share my old photos once again. If you’ve been DXing as long as I have maybe they’ll bring back memories of what you once heard. And if you haven’t been around that long you will have a better understanding of the good old days we oldtimers talk about.

Ecos Del Torbes

There is no better place to start this journey than with Ecos del Torbes. Using ten kilowatts on 4980 kHz, this Venezuelan broadcaster was possibly the most consistent station in the sixty-meter band throughout the 1970s, 80s, and 90s. If you were DXing the tropical bands during those years you surely logged them a few times. If you were lucky you may even have heard their one kilowatt signal on 9640 kHz. They were a very good verifier and for many DXers Ecos del Torbes was among the first Latin American stations QSLed.

Just after Christmas in 1994, my then-wife, four-year-old daughter, and I flew to Mérida in western Venezuela for a family vacation. For ten days we had a great time in this Andean city and then Theresa and Rebecca returned to Iowa while I stayed another week to visit radio stations. I was also getting paid by the Voice of America to research and write a study on the media scene in Andean Venezuela. The now very-out-of-date report can be read at my Patepluma Radio website (which hasn’t been changed in over twenty years and is in need of a facelift).

In that week I visited fifteen radio stations in six towns and cities and Ecos del Torbes was the highlight. I arrived at their doorstep unannounced but was immediately treated as an important guest. I was given a great tour and even got to sit in on a live newscast to see the famous Venezuelan doorbell being used live. I was there about ninety minutes and then walked a block up the street to sister station Radio Táchira. Their facilities were smaller but that’s where the technical offices were and Chief Engineer Ivan Escobar had been told to expect me. Ivan gave me a tour and invited me to visit the Ecos del Torbes transmitter site with him in the afternoon. On the way we stopped by his house where his wife had lunch waiting for us. Visiting Ecos del Torbes was not just the highlight of this trip but ranks as one of my all-time favorite station visits. These pictures bring back many good memories.

Ecos del Torbes was located in the second floor of this building in downtown San Cristóbal. The entrance was the door on the side.

The small plaque next to the door was easy to miss. I walked right by the first time.

Edgar Fabala of the news department showed me around. Here he demonstrates the mini-xylophones that Venezuelan stations used to make the distinctive ‘doorbell’ sound that separated items in the news reports.

Ecos del Torbes had one of the largest record libraries in Venezuela. The LPs were color-coded by type.

Julio Achila was a control room operator who had worked at the station since it opened in 1947.

This pennant was considerably larger than the ones sent to DXers.

Sister station Radio Táchira was located a block up the street on the fourth floor of this building.

Dipole antenna used for 9640 kHz.

San Cristóbal once had a third broadcaster on shortwave. Radio San Sebastian used 6070 kHz in the early 1970s. (They were not affiliated with Ecos del Torbes).

That was nearly three decades ago and a lot has changed. Ecos del Torbes and Radio Táchira have been gone from shortwave for over twenty years.

In 1995 Ecos del Torbes was at the corner of Calle 9 and Carrera 8, the same address as when I first QSLed them in 1972. Sometime since my visit they moved an outer neighborhood about two kilometers to the east. To find the new offices locate San Cristóbal on Google maps and then search for “Grupo Radial Gonzalez Lovera”. The transmitter site is still where I visited it and can be seen by plugging the coordinates “7.7885, -72.2725” into Google maps and switching to satellite view. (Ignore the picture that pops up to the side. That’s not it.) Zooming in, the medium wave tower is clearly visible but there are no signs of the old shortwave antennas. I suspect they were sold for scrap years ago. I never have found out where the Radio Táchira transmitter site was.

I’d love to go back to Venezuela someday and see some of the other cities that I used to listen to, such as Barquisimeto, Valencia, El Tigre, and Sucre. Unfortunately the political and economic situation there doesn’t look good and it doesn’t look as if it will improve any time soon. But when it does, I’ll be back.
