QSL Confirmation:

Due to differing regulations set by amateur radio licensing authorities across the globe, XSG will only confirm amateur radio QSOs and SWL reports via paper QSL cards delivered by mail. If you wish to receive an XSG QSL card, please send your card to: No. 1 Diantai Road, Zhangjiang Town, Pudong New Area, Shanghai 201206, PR China. Email: [email protected].

Important Reminder:

To be clear, contacts with XSG will be cross-band contacts where XSG will operate on its authorized frequencies outside of the amateur radio bands, and any amateur radio operator making contact will operate within their own allocated amateur frequencies as listed above. Operators should exercise caution when operating split cross-band, ensuring they do not accidentally transmit on top of another station within the amateur bands. It’s a good practice to regularly monitor your transmit frequency.

Please note that amateur radio operators are not permitted to transmit on XSG’s dedicated frequencies. Operators must adhere to the transmission requirements in their respective licenses. It is recommended that amateur radio enthusiasts consult their national licensing authorities regarding applicable regulations before engaging in communications with XSG.

We warmly invite amateur radio operators worldwide to participate in this event and look forward to celebrating this milestone together.

Worldwide Broadcast Frequency Allocation Table

Many thanks to SWLing Post contributor Alan, who writes:

Thomas,

You have been reviewing radios on your site lately, which has prompted me to produce an up-to-date table of all frequencies allocated to radio and TV broadcasting.

Worldwide radios need to tune any frequency up to 240 MHz. DAB+ in the 1.452 – 1.492 GHz band has been a failure. TV is as indicated.

Some chip manufacturers are making FM reception for the CIS and Japanese markets, they need to tune down to 47 MHz to cover all of band 1 for DRM.

Please note that DRM and DAB+ can transmit coloured slide shows to the screen in DAB+ and DRM receivers provided they have a colour screen included.

Carlos Explores Japan’s Radio Nikkei: A Unique Shortwave Listening Experience from Brazil

Many thanks to SWLing Post contributor Carlos Latuff, who shares the following guest post:


Exploring Radio Radio Nikkei

by Carlos Latuff

It’s been a while since I listened to Nikkei Radio, a Japanese commercial broadcaster that operates on shortwave for a domestic audience. If I remember well, the signal was very weak and, since I don’t speak Japanese, I didn’t know what the content of its broadcasts was about. But today, with the possibility of recording the audio, transcribing it and translating it, it has become more interesting to follow its programs on shortwave here in Brazil, more specifically in Porto Alegre (distance between Nikkei’s transmitter in Chiba, Japan, and Porto Alegre, Brazil: 18779 km).

Nikkei Radio 1 was founded in 1954 and Nikkei 2 in 1963, and at the time it was called Nihon Shortwave Broadcasting Co., better known by the acronym “NSB”. Some Japanese electronics manufacturers have in the past released receivers dedicated to receiving the signal from these stations (see below).

Today, the Japanese company Audiocomm has radio models whose packaging states that this receiver is compatible with Nikkei Radio; note the image alluding to horse racing (see below).

I haven’t been able to acquire any of these devices (yet), since they were basically produced for the Japanese public. But any receiver with shortwave bands can tune into Radio Nikkei. I use my good old XHDATA D-808 with a long wire antenna. In Porto Alegre, the best propagation is between 08:45 AM and 06:15 AM (UTC). In the late afternoon, the signal also arrives, but with a fair amount of static.

Both Radio Nikkei 1 and Radio Nikkei 2 operate on the following frequencies:

Radio Nikkei 1:

  • 3.925 MHz (in case of emergency)
  • 6.055 MHz
  • 9.595 MHz (in case of emergency)

Radio Nikkei 2:

  • 3.945 MHz (in case of emergency)
  • 6.115 MHz
  • 9.76 MHz: (in case of emergency)

On the station’s website https://www.radionikkei.jp/ you can find details of its programming, as well as broadcast times, including a table (in Japanese) with this information, which can be translated with the help of Google Lens.

Radio Nikkei also broadcasts its programming via streaming, however the platform used (radiko) is inaccessible to me here in Brazil (see message below).

Nikkei Radio is majority-owned by the business newspaper Nihon Keizai Shimbun and the Tokyo Stock Exchange, which means the station focuses mainly on the financial market. However, much of its programming, especially on weekends, is dedicated to horse racing, a popular sport in Japan. In addition to news, talk shows and music, the radio station also broadcasts evangelical preaching (!). One of these religious programs is called “True Salvation” and is sponsored by The Japan Gospel Mission, a Christian Protestant organization.

This heterogeneous mix of business, horses and Jesus Christ makes Nikkei Radio an interesting station to tune into, to say the least.

The radio listening sessions published here were made in the central Porto Alegre, Brazil, between January 15th and 19th, 2025.

Don Moore’s Photo Album: Chota, Peru

Don Moore’s Photo Album: Chota, Peru

by Don Moore

More of Don’s traveling DX stories can be found in his book Tales of a Vagabond DXer

For DXers of Latin American stations, the period from about 1978-1998 was the golden age of DXing Peru. Those years saw an explosion of shortwave broadcasting from small towns, especially in northern Peru. Most of the stations were unlicensed and few lasted long. I tell the complete story of the period in Tales of a Vagabond DXer. However, the book doesn’t have many pictures as that would have made it much more expensive to produce and to buy. Fortunately, this blog is a perfect place to share photographs.

In those days one of the biggest radio hotspots in Peru was the department of Cajamarca. Over one hundred stations broadcast on shortwave, however briefly, just from that department. Cajamarca is a special place to me because I visited the region in 1985 during the height of the radio boom and visited over a dozen stations in the towns of Chota, Bambamarca, Cutervo and Celendín and the city of Cajamarca.

Chota is the largest town in the central part of Cajamarca department and played an important role in the development of broadcasting in small provincial towns.  It’s about 140 kilometers north of Cajamarca but in between is cold barren Andean altiplano rising to over 4,000 meters elevation. In 1985 the bus ride took twelve hours and we encountered ice storms coming and going.

In 1985 Chota was a sleepy Andean town in a fertile river valley.

Radio Chota was already seven years old when I visited in March 1985. The station only had a medium wave license but also broadcast unlicensed on the out-of-band shortwave frequency of 6296 kHz where it was widely heard by DXers. Later they received a shortwave license and were assigned 4890 kHz but several years passed before they actually switched frequencies. Radio Chota was a success story and is still on the air today.  Most of the stations I visited in 1985 were not so lucky.

Radio Chota as heard on 6296 kHz in 1982 via On the Shortwaves:

Radio Chota as I heard it in Quito, Ecuador on 4890 kHz in 1997:

Radio Acunta was a more typical broadcaster of the period. The station broadcast irregularly in 1984 and 1985 with a homemade 100-watt transmitter. The station didn’t survive but the transmitter with its crystal-controlled frequency of 5800 kHz was a good starter set. Over the next several years DXers followed its movements around northern Peru as it was sold from one would-be station to another.

This picture with the homemade posterboard signs really captures the transient nature of broadcasting in rural Peru in the 1980s. Radio San Juan de Chota was on 5274 kHz for a few months in late 1984 and early 1985. I doubt they ever had permanent signs made. They did, however, have professionally printed envelopes.

Recording of Radio San Juan de Chota via On the Shortwaves:

Bambamarca is a smaller farming town 20 kilometers south of Chota. It was also home to several shortwave stations over the years. Radio Bambamarca had a short appearance on 5657 kHz in the mid-1980s.

Return to Chota

I always expected to return to the Cajamarca area someday. Finally, in November and December 2017, I revisited all the places I had seen in 1985 and more while researching my historical travelogue Following Ghosts in Northern Peru. A few months later, in May 2018, I returned to the city of Cajamarca and Chota with my DX travel buddies, John Fisher and Karl Forth. Continue reading
