Good Listening from Brazil on Shortwave in 2025

by Dan Greenall

Fifty years ago, there were dozens, if not hundreds, of Brazilian shortwave signals to hear on shortwave. As with the rest of the world, this is no longer the case. However, especially with the advent of remote SDRs to assist with the enjoyment of the DXing hobby, there are still a number of stations broadcasting from Brazil that are well worth a listen, even if you don’t understand Portuguese. Here is a sampling of what can be heard in 2025.

Radio Nacional da Amazonia 6180 and 11780 kHz

This is perhaps the easiest station to hear for overseas listeners. They run high-powered transmitters and have been widely reported in many parts of the globe. The station began a short daily broadcast in English and Spanish in late March, but I’m not sure if this is still going, as I haven’t checked recently. Here is a recording from April 18:

The transmitter power used by the next two stations is unknown, so the use of a remote SDR to hear them well may be required. Overseas listeners can look for them anyway, but note that their schedules seem to be irregular. Broadcasts consist mostly of popular music with frequent station ID’s in Portuguese between selections.

Radio Ancora (free radio?) Bahia, Brazil 6200 kHz

Recording 1 – September 13, 2025 at 2337 UTC:

Recording 2 – September 13 at 2358 UTC:

Recording 3 – September 14, 2025 at 0223 UTC:

Radio Casa (free radio?) Amparo, Brazil 5900 kHz

Recording 1 – September 16, 2025 at 2020 UTC:

Recording 2 – September 16, 2025 at 2015 UTC:

Recording 3 – September 24, 2025 at 2200 UTC.

The last two stations should be audible to DXers outside Brazil.

Radio Inconfidencia, Belo Horizonte, Minas Gerais 6010 and 15190 kHz

With 5 kW of power, Radio Inconfidencia gives a full identification in Portuguese at the top of most hours that includes callsigns, frequencies, and location. It is on the air around the clock.

Radio Inconfidencia full ID recording – September 16 at 2158 UTC on 15190 kHz:

Radio Inconfidencia second recording – September 15 at 2353 UTC on 15190 kHz:

Radio Voz Missionaria, Camboriu SC 5940 and 9665 kHz

Using 10 kW of power from the south of Brazil, Radio Voz Missionaria should be heard, at least on occasion, in many parts of the world. This station also operates 24 hours a day.

Recording – Radio Voz Missionaria – April 23 at 2357 UTC on 9665 kHz:

Hearing Alaska and Hawaii on shortwave

by Dan Greenall

Alaska

Since 1983, the New Life Station, KNLS, has been broadcasting from Anchor Point, Alaska. Beamed primarily to Asia, their signals were not received as well in parts of North America as they might have been otherwise. From my location in southern Ontario, Canada, I was able to make this recording of their interval signal (“Chariots of Fire”) on 7355 kHz in 1987 around 1300 UTC with announcements in a Chinese dialect.

The station is still on the air in 2025. I made this recording on October 23 around 1200 hours UTC, in which you can hear their current interval signal prior to sign on in English. Reception was made on 7355 kHz using a remote KiwiSDR in northern Japan.

You can check out other opportunities to log KNLS on websites such as Shortwave.Live

Hawaii

Back in the 1950s, the Voice of America had a transmitter in Honolulu, but that was long before my introduction to shortwave. In 1993, World Harvest Radio station KWHR began broadcasting from Naalehu, near the southern tip of the big island of Hawaii. This one was widely heard by DXer’s and I still have a recording made of their announcement from November 10, 1996 on 9930 kHz.

Unfortunately, the station went officially off the air in 2009, so now the only way to hear Hawaii on shortwave is the NIST station WWVH at Kekaha on the island of Kauai. You can hear them on 2.5, 5, 10, or 15 MHz whenever propagation conditions are favorable to your listening post, assuming other stations like WWV and BPM are not overpowering them.

Here is a link to a few WWVH recordings. The first, from 1971, was made in Ancaster, Ontario, Canada, when they were still called the National Bureau of Standards and were using the term “Greenwich Mean Time.”

The second one was made on December 1, 2024 using a remote SDR near Honolulu.

Finally, if you can copy CW (morse code) and listen carefully, there is a brief 8 second clip of WWVH sending their call letters twice. It is from pre-1971 when the station was located on the island of Maui. Aloha!

Algeria on Shortwave – Then and Now

by Dan Greenall

In the early 1970s, Radiodiffusion-Television Algerienne ran a modest shortwave service (no English) mainly for North Africa, the Middle East, and Europe. A copy of their schedule from the 1972 World Radio TV Handbook is shown.

As a fledgling DXer in 1971, I was fortunate to hear their signal on 9510 kHz from my listening post in southern Ontario, Canada. Even better, they responded to my request for a QSL with this attractive card.

Fast forward a quarter century to 1996. The international service of Radio Algiers could be heard at times here in eastern North America on 15160 kHz with broadcasts that included English. Here is a brief recording from November 3 of that year that I am lucky to have saved.

In July 2022, two new 300 kW transmitters located at Ouargla and Bechar were put on the air after several years of planning. These were to be used for the Radio Coran service in Arabic, but in May 2023, Ifrikya FM (the African Voice) was born with the objective of providing a pan-African voice by broadcasting educational, informative, and cultural programming from an African perspective.

Although there is no English, they can be spotted on shortwave on 13640 and 13855 kHz after their 1900 UTC sign on. If you can hear the same programming on these two frequencies, you will know you have them.

Here are two recordings made on October 19, 2025 using a KiwiSDR near Sao Paulo, Brazil. They were made one hour apart, the first at 2000 UTC and the second at 2100 hours.

13855 was noticeably stronger than 13640 on this receiver.

Bangkok Meteorological Radio: Can you name that tune?

Many thanks to SWLing Post contributor Dan Greenall, who writes:

Bangkok Meteorological Radio in Thailand broadcasts marine weather several times a day on 6765.1 and 8743 kHz USB in both Thai and English. An interval tune is played between the Thai and English segments that has left me trying to put a name to it for nearly a week as I play it over and over in my head. There seems to be a vague resemblance to “Love Me Tender” by the late Elvis Presley but now I’m looking for help. Can anyone “Name That Tune”?

Here is a recording made on October 9 around 1300 hours UTC using the LA6LU KiwiSDR in Thailand. Have Fun!

The 90 metre band – Then and Now

by Dan Greenall

A few decades ago, the 90 metre shortwave broadcast band used to be full of interesting and challenging-to-hear DX signals. In the 1974 edition of The Complete Shortwave Listener’s Handbook, author Hank Bennett reports on what you might expect to hear on these frequencies. There is a copy of this book on the Internet Archive. Here is a link to that specific page.

Also, this sample page from White’s Radio Log in the 1972 Communications World magazine shows a number of stations that could be logged in 90 metre band.

Here are a few links to recordings from my personal collection that have survived through the many years. These were all made between 3200 and 3400 kHz from my listening post in southern Ontario, Canada.

[Note: Click on each broadcast link to open the associated Internet Archive page with more info.]

Radio Bougainville, PNG 1971

Radio Rabaul, PNG 1971

Radio Santiago, Dominican Republic 1971

Radio Libertad, Santiago, Dominican Republic 1971

Action Radio, Guyana Broadcasting Service 1972

Radio Christian Voice, Zambia 1996

Malawi Broadcasting Corporation (MBC) 1997

Radio Maya TGBA, Guatemala early 1970’s

Radio Exitos, Dominican Republic 1971

Today, it seems that only a handful of stations can be found broadcasting in the 90 metre band. These would include WWCR in Nashville, the Voice of Indonesia, KCBS Pyongyang and Radio Mosoj Chaski in Cochabamba, Bolivia. As well, the Canadian time signal station CHU still continues to use 3330 kHz.

A recent recording of Mosoj Chaski Radio, a Christian broadcaster logged using a remote SDR in Lima, Peru, is presented here.

Although not in English, listen carefully and you can hear them give their frequency of 3310 kHz in the 90 metre band as well as their location of Cochabamba, Bolivia.

Vatican Radio – Then and Now

Many thanks to SWLing Post contributor Dan Greenall, who shares the following post:

When I began shortwave listening back in 1969, Vatican Radio was one of the first stations I came across. That same year, the late Dr. Richard E. Wood authored a book called “Shortwave Voices of the World” in which he writes some notes about the station that you can read here [PDF].

In fact, Vatican Radio was established in 1931 by none other than Guglielmo Marconi. It wasn’t until sometime after World War 2 that the present-day transmitter site was set up at Santa Maria di Galeria. A nice view of it is pictured on this 1970 QSL card.

By the early 1970’s, short English language broadcasts to North America were still included in their schedule as you can see from these pages in the 1972 World Radio TV Handbook [click to enlarge].

In 1983, Ken MacHarg, a former host of the DX Partyline on HCJB, was the author of a now out-of-print book entitled “Tune In The World”. Read Ken’s comments about Vatican Radio here.

Though their published interval signal (see WRTVH) was “Christus Vincit”, Vatican Radio could also be recognized by the bells of St. Peter’s, which you will hear in this recording from 1971 that I made from my listening post in Ontario, Canada: https://archive.org/details/vatican-radio-1971

In more recent times, I have read that shortwave broadcasts to North and South America, as well as Europe, ended in 2012. In addition, English language shortwave transmissions to Asia ended in 2017, though they could still be found online. A list of their current English language broadcasts, as found on short-wave.info is shown here:

Here is a recording made August 11, 2025 using a remote SDR in the UK, complete with “Christus Vincit” interval signal, as they began their African service on 9705 kHz.
