Where VOA’s Broadcast Infrastructure Stands Today (Radio World)

Shortwave retains a role in serving particularly difficult-to-reach audiences

Russia’s horrific invasion of Ukraine and its simultaneous blocking of Western media outlets has renewed public interest in shortwave radio broadcasters like the federally funded Voice of America.

Now managed by the U.S. Agency for Global Media or USAGM, VOA’s roots go back to 1941, when the U.S. government leased a dozen commercial broadcaster owned/operated shortwave radio transmitters for the VOA’s predecessor, the U.S. Foreign Information Service. (These shortwave transmitters were previously used by U.S. broadcasters to share content between their AM radio stations.)

The VOA came into being in 1942. It played a major role in broadcasting U.S. news and views to the world during World War Two and the Cold War. After the fall of the Berlin Wall, shifting government priorities, the emergence of platforms competing with shortwave, and budget cuts led to VOA’s language services, broadcasts and programming being reduced.

Today, “USAGM operates transmitting stations around the world, including in the U.S., Africa, Europe and Asia,” Laurie Moy, USAGM’s director of public affairs said in an email earlier this year.

“All of these stations are equipped with multiple shortwave transmitters, and four of these stations have a medium-wave (AM) transmitter each. In total, USAGM’s network consists of about 75 shortwave (ranging from 100 to 250 kW) and medium-wave (ranging from 100 to 1000 kW) transmitters.”

The agency also has access to shortwave and medium-wave transmitters via leases and exchange agreements with other broadcasters.

At present, USAGM produces content in 63 languages, 35 of which are aired on shortwave and medium-wave. VOA itself produces content in 48 languages, 18 of which are aired on shortwave and medium-wave.

“In terms of the agency’s shortwave network, shortwave continues to reach particularly difficult-to-reach audiences, such as in North Korea, western China, Afghanistan and elsewhere,” Moy told Radio World. [Continue reading…]

How do you find out about tornadoes if your religion doesn’t allow TVs or smartphones? (Courier and Press)

If a tornado or flash flood is imminent, most Americans find out about it through a smartphone or a television.

But as the National Weather Service was reminded in the wake of the deadly Dec. 10, 2021 Kentucky tornado, one segment of the population uses neither of those things: the Amish, who shun technology.

As meteorologists studied damage in the days that followed that storm, which killed 80 people and damaged hundreds of homes, they encountered an Amish community in Ohio County, Kentucky, and asked: How do you get severe weather information?

“They basically said they listen for the weather sirens from town,” said Derrick Snyder, a meteorologist with the National Weather Service. But as loud as storm sirens are, not everyone is close enough to hear.

A solution may be on the way, as the agency teams with a national radio maker as part of the Weather Awareness for a Rural Nation initiative. Snyder and other meteorologists are part of a project developing weather radios that will be both effective in relaying information immediately, but also acceptable for the Amish lifestyle.

It will be a stripped-down, hand-crank model with absolutely no modern amenities. Continue reading

Radio Waves: 83 years of ABC Broadcasting, AM to New Zealand Northland, and Taliban blocks RFE/VOA/Radio Liberty

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!


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…]

About

Aacharya J.C.Bose is well known as the “Father of Wireless Communication”.

Acharya Bose’s demonstration in 1895 & 1897 predates all.

Bose transmitted wireless signals to a distance of a mile. Popova in Russia was still trying remote signaling at this time & the first wireless experiment by Marconi was not successful until May 1897.

Bose is a pioneer in microwave optics technology.

Bose’s invention of 1-centimeter to 5 millimeters radio waves is being used in radars, satellite communication& remote sensing.

Bose’s concepts from his original 1897 papers are now incorporated into a new 1.3 mm multi-beam receiver on the NRAO (National Radio Observatory) 12 Meter Telescope.

Bose anticipated the use of P-type& N-type semiconductors & hence 60 years ahead of his time. Bose developed the use of GALENA crystals for making receivers.

In Bose’s presentation to the Royal Institution in London in January 1897, he speculated on the existence of electromagnetic radiation from the sun. This radiation from the sun was not detected until 1942.

A former Chinese soldier turned artist explains how a song on Radio Australia changed his life (ABC)

It was 1979 and Jian Guo was stationed at a military camp in Yunnan, a province in south-western China bordering Vietnam, when he listened to Radio Australia for the first time.

The then-17-year-old was patrolling the base one night when he saw a group of fellow People’s Liberation Army (PLA) soldiers tuning radio equipment on the back of a truck.

He initially thought they were intercepting enemy signals, but, as he got closer, he realised they were listening to a radio broadcast.

It was the ABC’s international broadcasting service, which was considered an “enemy channel” at the time.

“The so-called ‘enemy channels’ included almost every station outside mainland China,” Guo told the ABC.

“The biggest ones were the VOA [Voice of America] from the US, Voice of Free China from Taiwan, and Radio Australia.”

Guo had joined the PLA in 1979 during the peak of the Sino-Vietnamese War but, thanks to his talent in the arts, he was chosen to be a secretary of his company, so he could avoid fighting on the battlefield.

Apart from painting propaganda materials, he also looked after weapons and communication equipment like the radios, which was an extraordinary privilege.

He was not supposed to use the equipment he maintained, and was fearful of breaking the rules, but after seeing his comrades listening to the Australian broadcast the curiosity grew inside him.

One night, alone in his room, he turned on a radio.

It took a while for him to find the right frequency, because of the interference put out by China, but then suddenly he was listening to Radio Australia and the song that would change his life.

“It was broadcasting The Moon Represents My Heart by Teresa Teng,” Guo said.

“That was the first time I knew such music existed in the world.” [Continue reading…]

Voices in the Air: Sarah Johnston on 100 years of radio (RNZ)

Kia ora koutou k?toa. Thank you to RNZ and National Library for organising this celebration of the start of radio in New Zealand, 100 years ago tonight.

Tonight is something of a game of two halves: first I will talk about the first broadcast of voice and music by radio and the start of radio broadcasting in this country – and then I’m also going speak about a research project I am working on, radio recordings made of New Zealand’s forces overseas during World War II.

I have always been a huge fan of radio, ever since childhood listening to the Weekend children’s request sessions, and then as a teenager, eating my breakfast with Morning Report coming out of the family transistor beside me. As a radio journalist I became one of those voices and worked for RNZ and Deutsche Welle in Germany, where I experienced the power of voices coming out of the air from the other side of the world. And as a sound archivist working with the Radio New Zealand archives, I learnt that that power of the voice doesn’t diminish with time – listening to a voice from 80 years ago can transport you not just through space but also time. Sound to me, has a power that in many ways seems different to that of visual images. Continue reading

Guest Post: Jerome’s experiences as an SWL in Saudi Arabia from 1990-91

Many thanks to SWLing Post contributor, Jerome van der Linden, for the following guest post:


Experiences as an SWL in Saudi Arabia 1990 /91

by Jerome van der Linden

From about 1986 I worked for the Broadcasting Division of Telecom Australia (now “Telstra”), in Adelaide, South Australia. This Division of Telecom Australia had responsibility for installation, maintenance and operation of Australian Government funded broadcasting services (radio & TV) such as ABC (including Radio Australia) and SBS. In later years responsibility for this was taken away from Telecom Australia and handed to BAI.

I already had a life long interest in Broadcasting and short wave radio in particular, and I was recruited into a new non technical managerial position in the then new Broadcasting Division of Telecom Australia: it was the perfect job to my mind. In this period of the late 1980s, the organisation was heavily involved in the capital works to get Radio Australia Cox Peninsula (Darwin) back into operation, after it was largely destroyed by cyclone Tracy in 1975, as well as building the three Northern Territory vertical incidence (“shower”) services at Katherine, Tennant Creek, and Alice Springs (VL8K, VL8T, and VL8A respectively).  (The NT is probably about the size of a major US state like Texas). Apart from doing my non technical work, I took every opportunity to learn more and get involved in the technical side of things. On one occasion, when I knew that the technical staff would be testing the new transmission facilities on a range of frequencies, I was able to confirm with the onsite technician a booming signal into Adelaide from the Alice Springs transmitter he was briefly testing on 11715kHz in the daytime.

Alice Springs (VL8A) transmitter site in the last year is was operating (Photo by Jerome van der Linden).

As the opportunity arose, and as I was also part of the Southern Cross DX Club, I regularly participated in the Radio Australia DX program (I cannot even remember its name, 30 years later) that was produced by Mike Bird. I also contacted many rural cattle stations (equivalent to “ranches” in the US) that were spread throughout the Northern Territory to get them to report on how they were receiving the new NT HF service broadcasting stations when they came on the air. I saw it as a way of promoting the shortwave radio services throughout the Northern Territory.

My work gave me the opportunity to visit not just each of the new NT HF transmitter stations, but also included several visits to the Radio Australia (RA) facility at Cox Peninsula. While I also saw the old RA Receiving station on Cox Peninsula (dating from the period when signals were received from RA Shepparton and then re-transmitted from Darwin, in the period pre cyclone Tracy), this was at a time when that facility had already been largely dismantled.

In early 1990, I sought and was awarded a contract position with Telecom Australia’s Saudi project, and I was seconded to that from my job in the Broadcasting Division. From my own research, I knew that radio and TV in Saudi Arabia was quite unlike what I was used to, and I made it a point to take with me, on loan, a Sony ICF 2001D receiver. So it was in March 1990 that I arrived in Riyadh on a single person’s contract. I was allocated a 2 storey 3 bedroom villa for my own use among a large number of other identical villas occupied by other Telecom Australia staff, that were all located within a walled compound close to the Saudi Telecom offices.

Almost immediately, it was obvious that I would have to rely on the BBC World Service for my English news, as the KSABS radio services were nearly all in Arabic, and its TV service was even less appealing to me. I managed to string up some long wire antennas on the roof, and it was not long before I was also able to pick up services from Radio Australia. I got in touch with Nigel Holmes, then RA’s Frequency Manager in Melbourne, and was able to let him know how signals were being received in the Middle East, even though South Asia was about the limit of RA’s intended reach at that time. As my office was in the city of Riyadh some distance away, I was allocated a car for my own use, and – having found these were quite common – soon fitted it with a Short Wave capable car radio. In fact it was the one I reviewed in the 1991 WRTH.

The compound housing the many Australians and their families had its own CCTV system, and the Aussies were entertained by a regular supply of Australian VHS TV tapes. The same CCTV network was also used by Australians from the project making out as wannabee disk jockeys with their own programs before 7am and into the evenings.

As many people will recall, in mid 1990, Sadam Hussein, the then leader of Iraq, invaded Kuwait, and there was some concern he might continue and invade Saudi Arabia. As a direct consequence, radio with World news became even more important for the Australians,  and the many other expats working in the Kingdom of Saudi Arabia (KSA).

An unexpected benefit to the expats living in Riyadh was the arrival of thousands of US ground forces, who brought with them their very own AFN broadcasting services which operated on FM with their own high pitched professional female DJs who played the latest pop music. This was at a time when this type of music was not heard at all on local Saudi radio, and the only source we had of modern music was the many bootlegged copies of cassette music which were for sale everywhere (in addition to pirated copies of software).

When Sadam Hussein decided to stop international residents from leaving Iraq to travel home, their roles as ‘hostages’ caused international broadcasters to improve their services into the Middle East.

That included Radio Australia, and at least one of its Cox Peninsula transmitters was used to improve the signal to the Middle East in the hours up to its daily shutdown at midnight Darwin time (1430UTC). The strongest signal in those days was a 21MHz frequency, and it mostly boomed in. I recall one evening when the transmitter’s audio sounded very suspect to me. I made a quick international phone call direct to Cox Peninsula; spoke to the duty shift supervisor who I knew personally; described the signal to him; he picked the problem; switched the transmitter off and placed another transmitter online on the same frequency which gave clean audio, that I was able to confirm to him.

It was about this time that I realised my Sony ICF2001D had a feature I could use to the benefit of all my fellow Australians in the compound. In the first instance, I was able to arrange for an audio feed from the 2001D in my villa into the compound’s CCTV system, so that – provided someone plugged the audio in correctly – the signal from my Sony radio’s line out was relayed to every other villa that cared to listen. As I was absent during most of the working day, I used the Sony’s programming feature that allowed for up to 4 separate listening sessions to be set up. Each program required a SW frequency and start/stop times to be programmed. I think each session had a time limit of perhaps 4 hours. This enabled me to set the radio up to relay BBC World Service for most of the day switching automatically to certain frequencies as appropriate, and also provided the people with some brief Radio Australia segments with news from home.

In the period prior to January 1991’s, when George Bush had promised to retake Kuwait if Sadam Hussein did not withdraw, it was also interesting to pick up Iraqi broadcasts intended for (and to try to demoralise) American servicemen. Very strong signals from Baghdad were regularly audible, I seem to recall 11825kHz being one such frequency.

In the event, about January 16, 1991 the allies invaded Kuwait from Saudi Arabia, and made devastating air based attacks on Iraqi facilities. Radio Baghdad’s shortwave service did not seem to last very long after that.

We Australians were told in no uncertain fashion that Iraqi “Scud” missiles were ballistic (hence not accurately targeted), and would definitely not have the range to reach Riyadh in Saudi Arabia. The experts were wrong however, and a couple of scuds did reach Riyadh. As our compound was in the “flight path” from Iraq to the Riyadh airbase the Americans were using, it turned out we were not in the best location! The American forces had “Patriot Missiles” set up to intercept any Scuds that got through, but nobody told us that the Patriots break the sound barrier seconds after being fired, and that they’re only capable of intercepting Scud missiles just before they hit the ground. You can imagine the sonic booms that went off the first night Scud missiles arrived: I have photo in my home that some daredevil took outside, that proves all this.

We had been told to tape up the glass on our villas in case it should shatter, and that we should leave our TV sets tuned to our CCTV channel turned on at all times, with the volume up so that if there was an air raid the staff and their families could be alerted by means of a piercing alarm sound that someone had fiendishly created. And so it was that one Thursday, when Jonathan Marks had scheduled a telephone interview with me for Radio Netherland’s Media Network, we were discussing media events in Saudi Arabia when the air raid alarm went off, and we had to postpone the rest of the interview. I seem to recall that he did call me again later the same night and we finished things off. I never did get to hear the program, or I would have recorded it! As far as I know, it’s not one of the programs that Jonathan has been able to find to include in his on line media vault. If anyone else has a copy of this early 1991 edition, I’d love to hear it again.

As the experts had been wrong in their assessment, it was decided that most of the Australians would be removed from Riyadh, and I was sent to do my work from Jeddah, for about 6 weeks. Again it was a slightly different media environment, and while interesting, I missed the ICF2001D, and bought a cheap multi band analogue portable to be able to keep up to date with BBC World Service News broadcasts.

By early March 1991, most of the fighting was over, and it was safe for me to return to Riyadh, where I worked for another two or three months, before returning to my normal job and family in Australia.

Annual Armed Forces Day Crossband Test Postponed (ARRL News)

Due to the ongoing COVID-19 response and mitigation actions, the 2020 Armed Forces Day (AFD) Crossband Test scheduled for Saturday, May 9, has been postponed. Because it’s uncertain just when stay-at-home orders will be lifted across the US, AFD planners chose to postpone this year’s event, because the government stations that typically support this event may not be available. Armed Forces Day Crossband Test planners are considering scheduling a November event in honor of Veteran’s Day, depending on COVID-19 mitigation actions. During the AFD Crossband Test, military stations in various locations transmit on selected military frequencies and announce the specific ham frequencies they are monitoring to work radio amateurs. — Thanks to US Army MARS Program Chief Paul English, WD8DBY

World War II and Radio (All Things Radio)

I have added an article I wrote some years back on the code breaking efforts of the Allies during WWII. While certainly not exhaustive, I found many of the connections between countries and equipment rather fascinating, and new things continue to pop up regarding Bletchley Park’s role in training officers and decoding texts. While most famously known for breaking the Enigma code, also significant was the breaking of the Lorenz Cipher.

VI3RA: Last RF emanations from RA Shepparton before demolition (March 14-15, 2020)

Many thanks to SWLing Post contributor, Nigel Holmes, who writes:

Those of you who hold amateur (VK) licenses – form an orderly queue to book a spot.

Those of you who listen – make space on your shack wall for the last QSL card from Shepparton IHFTS.

A special callsign has been issued by ACMA for the event: VI3RA (Victor India…)

Amongst other experimental transmissions, will be an attempt will to reflect radio signals from the Moon using the high gain HF aerials at Shepparton. Frequencies in the 18 & 21 MHz amateur bands would be employed. This would emulate the ground-breaking work done by CSIR Radiophysics Laboratory in the 1940s from the Shepparton station which initiated Australia’s entry into radio astronomy.

Click here for more information about VI3RA at QRZ.com and SADARC.org.

Note that the event with take place March 14-15, 2020 (GMT +11:00).

Thank you for the tip, Nigel!  I’ll certainly attempt to put Shepparton in the logs! If I lived in anywhere near Shepparton, I’d make the pilgrimage to be in that long line of people hoping to light up one of those massive antennas!

I hope if any SWLing Post readers attend the event or operate as VI3RA, they’ll perhaps snap a few photos to share here with the community!
