Shanghai Coast Radio Station (XSG):

Those Giant Antennas!

The 17th of May is the World Telecommunication Day. It is also the open day of Shanghai Coast Radio Station. On this day, a group of amateur radio operators were invited to visit the transmission facility, a huge antenna farm, of the radio station, located on Chongming Island of Shanghai, the third largest island in China.

The transmission site of Shanghai Coast Radio Station is as shown below in the map of Chongming Island. Other sites of the station include a central control/receive station in Zhangjiang, a receive station on Hengsha Island and some VHF base stations in a number of other locations. All these locations in Shanghai, linked via cable and microwave connection, form Shanghai Coast Radio Station, also known by its callsign as XSG.

Presentation by Station Officials

Fifteen or so local hams were cordially invited to have a tour of the station. The radio enthusiasts were greeted by station representatives, including Mr Wan, Mr Wang, Mr Zhou and Mr Niu (BH4BFS), who also gave them an overview of the coast radio station’s history and development. 

Antenna Farm

Mr Wang then showed the visitors around the antenna farm. Many of us, myself included, saw and were deeply impressed with these huge antennas for the first time! Indeed, many professional radio facilities and operators of similar coast radio stations work quietly around the globe and around the clock to provide for distress, navigational, business and personal communications needs of ships!

The antennas cover a wide range of frequencies, from MF, HF, to VHF and UHF. Many of them are, however, shortwave (HF) antennas.

Transmitter Room

(I placed a Tecsun PL-330 radio near the transmitter at 12380.1 kHz (weather fax). The signal strength, in dbu, is 96. Given the margin of error of the receiver’s display, that’s probably as high as it could go.)

Shanghai Coast Radio Station (XSG) operates on a wide range of frequencies. Its HF frequencies include 4207.5, 4209.5, 4215.5, 4369, 6312, 6326, 6501, 8414.5, 8425.5, 8770, 8806, 12577, 12637.5, 13176, 13188, 16804.5, 16898.5 and 17407 kHz. Of particular note is that they have kept a CW frequency of 8665 kHz for general broadcast of information on a 24 hour basis.

The station’s VHF phone service covers 25 nautical miles of the coast. Its MF NAVTEX covers 250 nautical miles of the coast. And its HF phone and weather fax and HF NAVTEX extend to 1,000 nautical miles.

History and Current Status

Founded in 1905, Shanghai Coast Radio Station has been around 119 years. The XSG callsign has since remained in use.

China has in place DSC watch and NAVTEX broadcast in coast stations (including XSG) in accordance with GMDSS requirements. Among services provided by XSG are Radio Telephony (RT), Narrow Band Direct Printing (NBDP), “Voice of the East China Sea Coast” (voice broadcast on 161.600 MHz and 8806 kHz) and marine radio weather fax. The station is without a doubt one of the largest coast radio stations in the Asia Pacific region and plays an essential role in the region’s marine safety and communications.

QSL Cards

Shanghai Coast Radio Station issues QSL cards in Chinese and English, traditionally in paper form and nowadays electronically.

(This is an electronic QSL card issued to a Shanghai listener, who received their signal over the radio. Examples of QSL cards in English can be found online.)

Ham Station

Mr Niu of Shanghai Coast Radio Station, one of the tour’s organisers, is a ham himself with callsign BH4BFS. According to him, there are intentions to start a ham radio station within the establishment, possibly incorporating the letters XSG. However, there is much work to be done to make it happen. An amateur radio station with overlapping callsigns with a professional one would be really charming.

Passing by the Delano Transmitting Station

Many thanks to SWLing Post contributor, Tracy Wood, who snapped the photo above as he passed by this former IBB facility. Tracy noted:

The antenna field is still intact.
As a kid, the signals would leak into cheap AM radio sets in Oregon.

I could only imagine they would!  Thanks for sharing this, Tracy. Amazing to see that the antenna field is still standing.

AM Radio Transmitter Sites Now Valuable Real Estate for Logistics Industry (Transport Topics)

The familiar real estate adage “location, location, location” rings true these days for huge tracts on the outskirts of major cities — sites that for decades housed AM radio towers but that today command top dollar as e-commerce fuels rising demand for new warehouses and logistics centers.

Look no further than the $51 million sale of a five-acre parcel in Queens, N.Y., where an AM radio station will eventually abandon its existing tower and transmitter site, and move it.

New York radio station WFME’s owner, Nashville, Tenn.-based Family Radio, sold its AM transmitter site to Prologis, a San Francisco developer that specializes in building warehouses for companies looking to expand final-mile capability.

This property is situated near the Long Island Expressway, the Brooklyn-Queens Expressway, the Queens-Midtown Tunnel, and La Guardia and JFK airports. The spot’s current value as a logistics hub far outstrips its importance to a broadcast outlet that didn’t register in New York’s most recent radio ratings book.

“Long term, we see this as a strategic move that adds to our growing footprint of high-quality logistics space that offers quick and easy access to consumers.” said Jeremiah Kent, Prologis senior vice president of value added investments. “In one of the most densely populated markets in the world where demand for logistics real estate is high and land is scarce, Prologis is well-positioned to respond to the acceleration of e-commerce and consumers’ expectation for same- and next-day delivery services.”

The rising value of these locations is being driven by changing consumer habits and rapid technological evolution. Sites on the edge of town that in radio’s heyday were cheap and plentiful can now house vital links in a supply chain propelled by technology that was hard to imagine back in AM’s early days.[]

USAGM CEO Names New Leaders for RFE/RL, OCB (VOA)

WASHINGTON – The U.S. Agency for Global Media announced that former VOA journalist Ted Lipien will return to run Radio Free Europe/Radio Liberty and Jeffrey Scott Shapiro, the current acting director at the Office of Cuba Broadcasting, will become director.

The appointments follow USAGM CEO Michael Pack’s December 9 announcement that former Voice of America director Robert Reilly would return to lead that network.

Lipien joined VOA in 1973 and worked as the chief of the Polish language service and later as a senior news and marketing executive until 2006. For 10 years, Lipien worked in Munich and Prague as the Eurasia regional marketing director, helping VOA and RFE/RL place programs on stations across the region. In an announcement sent to staff, he recalled listening to Radio Free Europe while growing up in communist Poland.

“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,” he wrote.

Since leaving U.S. broadcasting, Lipien has been a vocal critic of VOA’s and USAGM’s previous leaders. He has also defended Pack’s tenure as CEO, saying Pack has focused on correcting long-running issues of bias and mismanagement at the networks.

Radio Free Europe/Radio Liberty is a nonprofit multimedia broadcasting organization funded by U.S. Congress grants. Based in Prague, it serves as a surrogate media source in 27 languages, mostly in places where a free press remains either banned or not fully established.

Jeffrey Scott Shapiro has been with the Office of Cuba Broadcasting since July 2017. In announcing Shapiro’s new position, Pack cited his deep connections to local communities in South Florida and his track record in producing objective news.

“Transmitting objective news and information to the island plays a critical role in moving toward a free Cuba, and it is a privilege to be a part of such an important mission,” Shapiro wrote in a published statement.

The Office of Cuba Broadcasting oversees Radio and Television Marti, based in Miami, Florida. The network provides news, information and analysis to the people of Cuba via satellite television and shortwave radio, as well as flash drives, DVDs and text messages.

Pack was confirmed by the Senate as CEO in June with a three-year term and fired several news executives upon his arrival. He later declined to testify before a House of Representatives panel examining his decisions at the agency, including his decision to fire the heads of RFE/RL, Radio Free Asia and OCB, and replace their boards. The then-director of VOA, Amanda Bennett, resigned two days before Pack joined the agency.

Last month a federal judge granted a preliminary injunction prohibiting Pack and other USAGM officials from interfering with the editorial independence and First Amendment rights of journalists at VOA and other networks they oversee. The ruling still allows Pack to appoint leaders of those news networks to oversee them.

The November 20 court order prohibits the CEO and other defendants from communicating directly with journalists at the networks without the consent of their directors. The order is part of a lawsuit filed by five USAGM officials whom Pack placed on administrative leave in August. The suit accuses Pack and his political appointees of unlawful actions and of violating the First Amendment and a statutory firewall set up to ensure editorial independence. Pack has said the lawsuit is “without merit” and that all of his and his team’s decisions and actions are “correct and lawful.”

Earlier this month, a federal office set up to protect whistleblowers ordered USAGM to investigate allegations of wrongdoing by its own top officials.[]

All new car radios to have digital terrestrial radio (Southgate ARC)

From today, people purchasing new passenger vehicles across Europe will be able to benefit from the advantages of digital radio – greater choice, clearer audio and enhanced data services.

Article 113, Annex XI in the EECC states that “Any car radio receiver integrated in a new vehicle of category M* which is made available on the market for sale or rent in the Union from 21 December 2020 shall comprise a receiver capable of receiving and reproducing at least radio services provided via digital terrestrial radio broadcasting”.

The regulation applies to all EU member states – regardless of the status of DAB in each country.

Despite the impact of Covid-19, Germany, France, the UK, Italy and Denmark have already introduced laws mandating digital terrestrial radio in cars and other countries are expected to follow shortly.

In the first half of 2020, over 50% of new cars sold in Europe included DAB+ as standard – a number that is expected to reach 100% by the end of 2021 as DAB+ adoption continues to grow across Europe.

More information and regular updates on the EECC directive and its implementation across Europe is available on the WorldDAB EECC factsheet.

*Motor vehicles with at least four wheels designed and constructed for the carriage of passengers

North Korean fisherman publicly executed for listening to foreign radio (The New Daily)

A North Korean fishing boat captain has been publicly executed for listening to banned foreign radio stations while at sea.

The man, only known by his surname Choi and said to have been in his 40s, was killed by firing squad in front of 100 boat captains and fisheries executives, according to a Radio Free Asia report.

Choi, who owned a fleet of more than 50 ships, is thought to have been turned in by a crew member after they turned against him.

According to the RFA report, Choi ultimately confessed to authorities and was charged with “subversion against the party”.

“In mid-October, a captain of a fishing boat from Chongjin was executed by firing squad, on charges of listening to Radio Free Asia regularly over a long period of time,” a North Korean law enforcement official told RFA.

“They publicly shot him at the base in front of 100 other captains and managers of the facility’s fish processing plants. They also dismissed or discharged party officials, the base’s administration and the security officers who allowed Choi to work at sea.”

The network said the fishing boat captain began his habit of tuning into foreign radio stations, including RFA, while serving as a radio operator in the military. He had listened to RFA – a US-government funded network that broadcasts in Korean – for 15 years.

“The security authorities decided then that the time to re-educate him had long past, so they executed him by firing squad,” the source said.

“It seems that the authorities made an example out of Choi to imprint on the residents that listening to outside radio stations means death.”[]

My buddy, Rob Wagner (VK3BVW), has just posted an article with detailed photos of the Brandon Antenna farm on his excellent blog, the Mount Evelyn DX Report.

Rob introduces his article:

During our recent two month trip north from Mount Evelyn through Queensland and New South Wales, we had an opportunity to visit the former Radio Australia transmitter site near the little town of Brandon, about 85 km southeast of Townsville in Far North Queensland. Well, actually I visited the site while my wife Jan sat in the car, exhibiting a state of relative boredom!

Officially, I had not made arrangements to inspect the transmitters. We were just passing through the town one warm Sunday afternoon. The site is only 5km out of Brandon on Jack Road. The topography is quite flat, making it ideal land for the sugar cane plantations that grow vigorously throughout this region. Here you’ll find the powerhouse 50 kW mediumwave outlet of 4QN Townsville on 630 kHz with local programming from the ABC North Queensland studios. This frequency is well heard across a 250 km radius during the daytime, and easily heard throughout most of Queensland (and well beyond) in the evenings. Indeed, 4QN has been broadcasting reliably from the Brandon site to its local communities throughout all sorts of weather including many tropical cyclones since 1958.[…]

North Carolina Public Television features VOA Greenville

This is an excellent video about the VOA Greenville transmitter site produced by North Carolina Public Television. What I love most is the time they took to explain the importance of shortwave radio across our globe, how it is an existing technology that governments and regimes cannot easily block or track. We certainly repeat this theme often, here on the SWLing Post.
