RTI – Taiwan on direct broadcast from Tamsui transmitter center

As in recent years, the German and French services of RTI – Radio Taiwan International – will broadcast their programs to Europe and North-West Africa from the Tamsui transmitter center.

To determine which two frequencies will be used for the retransmissions, tests will be carried out on three frequencies in 10-minute increments, as follows:

Saturday July 6, 2024 by the German service:

    • 11,995 kHz (17:00-17:10 UTC) – 9,545 kHz (17:30-17:40 UTC) – 7,250 kHz (17:45-17:55 UTC)
      report your reception observations to the German service: [email protected]

Sunday, July 7, 2024 by the French service:

    • 11995 kHz (Angle 325 degrees)?17:00-17:10 UTC – 9545 kHz (Angle 315 degrees)?17:30-17:40 UTC – 7250 kHz (Angle 315 degrees)?17:45-17:55 UTC
      Report your reception observations to the French service: [email protected]

Official broadcast dates:

German service: every Friday, Saturday and Sunday from July 12 to August 4, 2024

UNESCO World Radio Day 2024: Club du Perche contribution

Many thanks to SWLing Post contributor, Paul Jamet, who shares the following contribution to World Radio Day 2024 on behalf of the Club du Perche:


Word Radio Day 2024

Paul JAMET

Member of the Radio Club du Perche

Among the framing elements of the 2024 edition, UNESCO states on its website that the celebration highlights three important values:

UNESCO – The indelible history of Radio and its powerful impact upon news, drama, music, sports …

P.J. – Radio is a grand lady, a hundred years old, still young at heart and full of projects! Its birth and history have given rise to numerous publications and captivating accounts, because for over a century, radio has been the world’s sound memory. Radio stations regularly draw on their rich archives to help us relive key events, because history informs the future. Since the 1920s, radio has demonstrated its usefulness in explaining how the world works, educating listeners and providing entertainment (music, theater, sports, etc.).

UNESCO – The ongoing utilitarian value of Radio as a relatively free and portable public safety net during emergencies and power outages brought on by natural and human-made disasters such as storms, earthquakes, floods, heat, wildfires, accidents and warfare.

P.J. – In recent years, with the increasing number of conflicts and natural disasters resulting from climate change, radio has taken on a new and extremely important role, that of providing a public safety network for both emergency resources and victims. Dozens of models of portable emergency receivers are already available, while others are arriving on the market all the time, using new technologies such as the digitization of radio signals, the use of emergency frequencies for broadcasting warning messages: NOAA frequencies in North America, EWF (Emergency Warning Functionality) technology with DRM broadcasting, and expected also with DAB+ broadcasting.

UNESCOThe continuing democratic value of Radio to serve as a grassroots catalyst for connectedness within underserved groups including immigrant, religious, minority and poverty-stricken populations; and as an instantaneous bellwether of public opinion expressed through the auspices of free speech in the public space.

 P.J. – I was born after the Second World War. My mother often told me about the importance of [clandestine] listening to Radio Londres broadcast by the BBC to occupied France. At the time, the BBC was broadcasting messages to the Resistance operating in France and other European countries. Since then, radio has played a decisive role in many similar situations. Such was the case with Radio Free Europe and Radio Liberty until the fall of the Berlin Wall in November 1989. More recently, a few days after the outbreak of the Russian-Ukrainian war, some stations reactivated their Shortwave transmitters to broadcast special programs to the conflict zone – Zone CIRAF 29. 

Since the start of the third millennium, or even before, several countries have abandoned international broadcasting for a variety of reasons: financial, but also linked to the declining audience, preferring to use the Internet, at least in the best-equipped countries. Many stations have disappeared, and not the least, stations that made a major contribution to the plurality of information and points of view, such as RCI – Canada and RSI – Switzerland, not forgetting DW – Germany and ABC – Australia. Some countries have even demolished their installations and taken down their antennas! 

Yet there are still vast areas of the globe without Internet access or a reliable Internet network. There are still countries where freedom of information is severely controlled. 

In a recent article published on the Radioworld website, Kim Andrew Elliott, who produced “VoA Radiogram”, argues for a revival of Shortwave by proposing Shortwave 2.0, essentially using the following argument: « radio is the ultimate internet circumvention tool ». The author criticizes DRM for dropping out when transmission conditions are poor. He prefers text transmission via the system he has experimented with, which he believes to be more robust. Finally, he adds that « international broadcasters should not close any more shortwave transmitting sites. They are essential facilities to relay information when the internet is blocked, which will happen in more places, more frequently and more thoroughly ».

Through regular listening and exchanges, I fully support international radio stations for the indispensable role they play in providing a plurality of information, but also in providing entertainment (there are many cultural programs) and education, enabling the discovery of other countries and, above all, a better understanding of other cultures.

 As for the Clubs d’écouteurs, they have had to adapt to changes in the radio landscape and advances in information technology.  On the strength of its 40 years of existence and experience, the Radio Club du Perche wishes to take up these challenges and continue its role of promoting international broadcasting – particularly French-speaking – by adapting as best we can to the technological evolutions that are taking place. 

In conclusion, international shortwave broadcasting not only makes sense, but is still very useful for a large number of listeners or in certain situations. Nevertheless, it must adapt to the new realities of modern communication if it is to remain relevant and viable.

Paul explores the incredibly affordable XHDATA D-219

Many thanks to SWLing Post contributor, Paul Jamet, who shares the following article that was originally published in the Radio Club du Perche Newsletter.

Note that Paul also includes information about the new XHDATA D-109 and an XHDATA sale in the addendum of his article!


Let’s discover the XHDATA D-219

by Paul JAMET

A truly incredible performance/price ratio

A year ago, many people wondered if it was wise to resume short wave broadcasts to Russia and Ukraine (CIRAF Zone 29). Although a century old, this technology is still widely used around the world. Moreover, the world market for Short Wave receivers is apparently doing well because new models are regularly arriving on the market, in particular ultra-portable DSP receivers with surprising performance. As proof, the latest XHDATA model: the D-219, marketed since November 2022. This is a very easy-to-use receiver, with a vintage look and a needle dial, which is available in gray or silver, for less than $7 (excluding shipping and batteries) on the XHDATA company website.

The D-219 is a “Full DSP” receiver which allows it to be very sensitive and power efficient. It is powered by two AA/R6 rechargeable batteries or by the mains (batteries and 220/5.0 volt adapter not supplied). A small multilingual manual – including French – is provided.

From my point of view, the most important innovation – on a DSP receiver of this price – is the possibility of precise tuning when searching for stations with a pointer dial; there is absolutely no play, which allows perfect and stable tuning to the desired frequency. This receiver has a 3.5 mm jack, a rear stand and a hand strap. The 7-core telescopic antenna is about 55 cm long and provides good reception of FM and SW stations. The sound quality is very good for this 150g receiver (without batteries)! It has two FM bands (87-108 and 64-87 MHz), the AM band (Medium Waves) from 522 to 1620 kHz and nine SW bands from 4750 to 22000 kHz. See photo above.

For a SWL, it’s a real pleasure to explore the 9 Short Wave bands. For instance, I have already easily tuned to international stations several thousand kilometers away only with the telescopic antenna, such as RFA – Radio Free Asia – broadcasting from Agignan Point and Tinian Island in the Pacific Ocean.

Audio samples:

VoA in Dari from Udon Thani on 12075 kHz (250 kW; 9900 km):

RSI in English from Kall Krekell on 6005 kHz (1 kW; 350 km)

Note: A 23-foot wire antenna was clipped onto the whip antenna
recordings made by placing my smartphone near the speaker of the receiver.

QSLs

I received two QSLs (Year of the Rabbit) sent by RFA. See attached images below. These QSL confirm my reception reports (recordings made with the XHDATA D-219 and sent to RFA)

Summary

In conclusion, the XHDATA D-219 is really very easy to use. I can only recommend it to anyone who wants to start exploring the wide world of shortwave with a receiver that offers a truly amazing performance/price ratio!

NB: DSP technology –  Digital Signal Processing – allows, among other things, to reduce noise and limit distortion; it is perfectly adapted to the processing of radio signals.
