Radio Bonaire 1530: A Mediumwave Station Built for Emergencies

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

Hi Thomas

Radio Bonaire 1530 went on the air July 27, 2026.

According to its website,

“Radio Bonaire 1530 is your source of information during emergencies, specifically for residents and visitors of Bonaire. Thanks to an off-grid system and continuous broadcasting, you stay informed at all times, even during power outages or other emergencies.”

It continues:

How did the idea come about?

During the major, prolonged blackout of 2023, all sorts of things went wrong.

The FM transmitters located at Subi Rincon had no audio; the studio also had no power, so nothing was being sent to the FM transmitters.

Most FM stations had already gone off the air, and those still broadcasting had no sound. Eventually, these stations also went off the air as their backup power ran out.

For many, the internet was also inaccessible because the Wi-Fi modems in their homes had no power.

Phones could still be used for quite a while; however, making calls was virtually impossible because everyone wanted to do so at the same time. But after 36 hours, the telephone connections also failed one by one.

In response, a few amateur radio enthusiasts put their heads together. Some already had experience setting up so-called LPAM transmitters in the Netherlands—LPAM stands for Low Power AM on the medium wave band. These LPAM transmitters achieved a remarkably wide range despite their low power output (400 watts).”

You can find more information on their web page at: https://bonaire1530.nl/en/

I came across the station last night, purely by chance, while doing some random tuning on a KiwiSDR located, where else, but on Bonaire. Here is a recording that I made around 0400 hours UTC.

While most of the announcements (about the 3:20 mark) are in (presumed) Dutch, there is a brief one and a jingle in English.

Snail Mail QSL’s – A few stories from a bygone era

by Dan Greenall

Before the days of the internet and e-mail, the most common way for the listener to contact a radio station was to mail them a letter. This would include requests for a QSL card or letter, which would “officially” verify that reception took place and the details heard were accurate.

Waiting for a reply was part of the SWL experience. A few weeks would go by, sometimes months, and the anticipation would build. I would arrive home from school or work each day in hopes of finding an envelope bearing exotic-looking stamps from halfway around the globe in my mailbox. This was the ultimate reward! Although I didn’t realize it at the time, many of these QSL’s would one day bear historical significance.

Today, I have to admit, much of that magic is gone. With the advent of online streaming and the availability of remote SDR’s, broadcasters are understandably less enthusiastic about receiving a report from a distant listener. Though I have one or two email QSL’s, I have not mailed out a reception report since 1999.

It was to Radio Veritas Asia in the Philippines, and their card finally arrived in 2001.

Some of my favorites were personal replies from a staff member at the station.

Examples are these 1986 letters received from FM stations KKAZ in Cheyenne, Wyoming, and KCME, Manitou Springs, Colorado, informing me that I was their most distant listener on the date of reception.

As well, B. Rudolph Paulus, the station manager at a low-powered maritime station in Rabaul, Papua New Guinea, typed out a long friendly letter and even included eight colour photographs of the station, equipment, and staff members.

That was in 1988. Six years later, Rabaul suffered from a devastating volcanic eruption, and the fate of the station is unknown.

In some countries, the postal service could be irregular at best, so one could really never know if your letter got delivered. Then again, there were times when a station would fail to write my complete address on the card or envelope before mailing it. Fortunately, these managed to reach my hometown, where the folks at the local post office seemed to know who I was and added the missing information. These ones from Congo and the USSR were lucky to arrive.

As a radio amateur VE3HLC in 1978, I was thrilled to receive this beautiful postcard from a station I had contacted in the jungles of Guyana.

A few months later, I was horrified to learn of the unspeakable tragedy that had occurred at the Peoples Temple in Jonestown.

Even the postmark could prove significant, as evidenced by this card from Radio Nacional de España that came direct from their relay site at Santa Cruz de Tenerife in the Canary Islands.

In 1992, the island of Palau was still being governed by the U.S. The postmark on this card from KHBN shows the old zip code they once had.

Many long-time listeners continue to keep these historical treasures tucked away in boxes or albums, waiting for their stories to be told. What is your most memorable QSL?

Recordings: VOA Chinese and Possible Co-Channel QRM

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

The Voice of America is currently using its Tinang, Philippines site for a broadcast in Chinese beginning at 2100 UTC on 9535 kHz.

Here are 2 recordings of their sign-on with English ID and Yankee Doodle, one using a Kiwi SDR in Athens, Greece, and another using a Kiwi SDR in Taiwan (closer to the target area).

Athens, Greece

Taiwan

The signal starts out OK around 2157 with a test tone prior to Yankee Doodle, but seems to suffer from QRM from a co-channel station signing on after a minute or so. CRI is listed as using 9535 at other times, but perhaps this is a deliberate attempt to make the reception of VOA “uncomfortable”?

1976 U.S. Bicentennial Callsigns

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

Hi Thomas,

In 1976, amateur radio operators in the United States were allowed the option of using a special prefix in place of their regular one to celebrate the country’s bicentennial year. Many amateurs issued special QSL cards for this bearing the new prefix, making reference to the US bicentennial year on the front.

Others simply modified their existing cards. The bicentennial commissions in Massachusetts and South Dakota even made up fill-in-the-blank commemorative QSL cards.

WL1CEN was a special events station in Lexington, Massachusetts, that appears to have been operating earlier in 1975.

The American Radio Relay League also issued a bicentennial WAS award to amateurs making contacts with all 50 U.S. states during 1976.

Here is a link to more bicentennial QSL’s

I wonder what’s going on this year, as I am not QRV at the moment?

Time Stations from the 1970s Heard in Ontario, Canada — And What You Can Still Hear Today

by Dan Greenall

Time and standard frequency stations have been around for a long time.  In my early years of DXing, there were more than 20 of them scattered all over the globe.  These two pages from the 1972 World Radio TV Handbook show what could be heard back then, along with the frequencies used.

A page from the 1975 WRTVH indicates the arrival of BPM.

I managed to log at least ten of them from my listening post in southern Ontario, Canada.  They are listed below, some of them including links to recordings I made, have survived for over half a century.

WWV, Fort Collins, CO   (change of format in 1971)

WWVH, Kekaha, Kauai, Hawaii

YVTO, Caracas, Venezuela

LOL, Buenos Aires, Argentina

VNG, Lyndhurst, Victoria, Australia

JJY, Tokyo, Japan

BPM, Shaanxi Province, China

CHU, Ottawa, Ontario, Canada

RID, Irkutsk, USSR

FTK77, Bureau International de l’Heure, Paris, France

A link to some of their vintage QSL cards can be found here: https://archive.org/details/vng-australia-1971

Time stations in 2026

Today, only a handful of these time signal stations remain on shortwave.  Most are listed below.

BPM, Shaanxi Province, China (70 km northeast of Lintong)   2500, 5000, 10000 and 15000 kHz

ID given twice per hour during the 29th and 59th minute.  BPM was sent 10 times in CW, then the announcement in Chinese was given twice.

RWM, near Moscow, Russia   4996, 9996 and 14996 kHz

ID’s given twice per hour.  During 9th and 39th minute, RWM sent 21 times in CW.

CHU, Ottawa, Ontario Canada   3330 kHz, 7850 and 14670 kHz

ID and time announcement (English/French) in UTC, last 9 seconds of each minute.  Scheduled to close June 22, 2026.

WWV, Fort Collins, Colorado, USA   2500, 5000, 10000, 15000, and 20000 kHz

Time announcement (UTC) in English, each minute (male voice).  Station ID at :00 and :30 minutes.

WWVH, Kekaha, Kauai, Hawaii   2500, 5000, 10000 and 15000 kHz

Time announcement (UTC) in English, each minute (female voice).  Station ID at :29 and :59 minutes.

Best to log the remaining ones before their time runs out.

DXing from another country – Bermuda 1975

by Dan Greenall

A half-century ago, long before the internet, e-mail, and SDRs, I was fortunate to visit the islands of Bermuda. In addition to meeting up with a fellow amateur radio operator, whom I had contacted from my home QTH in Ontario, Canada, I was able to do some listening on the AM broadcast band, as well as FM, on an inexpensive portable receiver from Radio Shack that I had brought along with me. To this day, I still have the recordings of a few medium wave “catches” that I made, a few from the Caribbean, and a few from the eastern seaboard of the U.S. and Canada.

You can hear them by following this link to the Internet Archive.
https://archive.org/details/bcb-dx-from-bermuda-1975

As well, I recorded station ID’s of all the AM (3) and FM (2) local radio stations in Bermuda.

According to the 1975 World Radio TV Handbook, there were only 4 FM outlets, as the 94.9 FM outlet is not listed. Here is the link to these on the Internet Archive.

Today, I can DX from another country without leaving home (through the use of various worldwide SDR’s), though I have to admit that some of the magic is missing.

VOA Hitting the Target in Korea

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

Hi Thomas,

Judging by the 60 dB over S9 signal strength on a Kiwi SDR receiver in South Korea, I would say the Voice of America is getting into its target area very well.

They have a Korean language broadcast on 9310 kHz beginning at 1530 hours UTC using their Tinang transmitter in the Philippines. I made a couple of recordings, which are as follows:

April 29, 2026, leading up to 1600 hours UTC (programming in progress), presumed news about King Charles’ visit, “VOA” heard a few times around 3:04 and 3:10:

April 30, 2026, starting at 1527 UTC, open carrier with tone, carrier off after 40 seconds. carrier back on around the 1:44 mark with English ID and Yankee Doodle briefly, then off, Yankee Doodle resumes at the 2:03 mark, then programming in Korean:

Since my original post on March 9, I’ve noticed the Voice of America is no longer using 7500 kHz for its 2200 UTC broadcast in Mandarin Chinese. According to short-wave.info, they are now using 9625 and 11590 kHz from 2200 to 2230 UTC. Shortwave.live has them here as well, but in recent checks using remote SDRs, I have been coming up empty on 9625, and a bit of a mess on 11590. Other listed times and frequencies checked for the Mandarin service have not been heard either.
