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.

Sunshine and shortwave

Mark’s First Impressions of the PK MW Loop

by Mark (M7MHY)

It was while travelling in the Greek islands a few weeks ago, I first spoke to Paul Karlstrand.

I’d sent him an email, requesting a shipping quote from his home country in Australia to mine, Scotland, UK. I got a prompt reply, and he was only too happy to answer any questions I had, not only regarding shipping, but with any other queries I may have had concerning his loops. What a nice guy.

Fast forward to present day and I’ve been using his 36cm MW passive loop (catalogue code ‘TAM’) for a few days now. From paying the invoice through PayPal, the loop being built and assembled, to arriving on my doorstep around 11,000 miles later – it took just 10 days.

The free pen is a nice touch!

This is most certainly not a review of the antenna, it’s just a quick note on my observations and experience from the hours of enjoyment I’ve now had using it.

My conclusion? It’s brilliant.

I’ve caught several stations now generally not audible through the day with the Tecsun AN-200. The signal gain of the larger 36cm diameter PK loop compared with the 22cm Tecsun, improves reception quite drastically. Combined with a ‘split band?’ switch from 525 to 710kHz in the left position and from 710 to 1725kHz on the right, it does a great job of matching the radio’s tuned frequency to the loop without feeling finicky while turning the knob.

MW band is split into two sections

Of course, during grey line propagation or after dark, things just keep getting better. I have a few low power ‘test’ stations that I’ll use to check conditions and test radios and antennas with and am pleased to report, that the PK Loop 36cm performed remarkably in its job of funneling those weak signals into my receiver.

Pulling in some weak signals during the twilight hours

These products are very well made and are obviously manufactured with passion, care and attention. I think it would be very difficult to break or damage one, within the confines of normal use.

As soon as I can think of an elaborate enough story to tell my other half, explaining why another large package has arrived from Australia – I can see myself ordering the larger 50cm version from Paul, too.

“Holocaust” 1978 TV Mini Series Underground Radios – Warsaw Ghetto

Many thanks to SWLing Post contributor Fred Waterer, who shares the following screenshots and writes:

A pair of screenshots of an underground receiver and antenna as imagined in the 1978 mini-series “Holocaust,” Part 4 of 5.

IIRC it ran Holocaust 5 consecutive nights in 1978. Some big names, including Meryl Streep, James Woods, and a very chilling performance by Michael Moriarty.

“Holocaust won Emmy Awards for Outstanding Limited Series, as well as acting awards for Meryl Streep, Moriarty, and Blanche Baker. Morton Gould‘s music score was nominated for an Emmy and a Grammy Award for Best Album of Original Score for a Movie or a Television Program.”

“Holocaust Part 4: 1944-1945” TV Mini-Series (1978) – Meryl Streep & Michael Moriarty

The whole thing is worth watching.

The Voice of Independent Myanmar: A new shortwave broadcast providing news to Myanmar

Many thanks to SWLing Post contributor Tracy Wood, who shares this fascinating report from Mizzima about the launch of “Voice of Independent Myanmar,” a new weekly shortwave broadcast aimed at providing independent news and information to listeners in Myanmar.

The new service, a collaboration between Mizzima and Reporters Without Borders (RSF), airs Sundays from 7:00–8:00 AM Myanmar time on 17,665 kHz. The programming includes local and international news, analysis, practical information, and features on human rights and disinformation.

Yet another powerful reminder of why shortwave radio remains so important. Unlike internet and cellular networks, shortwave can reach across borders without relying on local communications infrastructure—and a simple battery-powered receiver can be enough to access it. In a country experiencing censorship and periodic internet shutdowns, that can make shortwave a remarkably resilient lifeline for independent information.

Demod: A New iOS/iPadOS App for Exploring Remote Receivers

Many thanks to SWLing Post contributor Alphonse, who is an SWL and independent app developer, who recently reached out to introduce Demod, a new iOS/iPadOS receiver app designed for exploring shortwave and other radio signals via remote receivers.

Demod connects to KiwiSDR, SpyServer, and rtl_tcp servers, and includes a built-in directory of public receivers, so you can start exploring even if you don’t have any radio hardware of your own. One particularly intriguing feature is its Identify function, which uses the HFCC broadcast schedule, your receiver’s location, and the current UTC time to help identify the station you’re hearing, including its language and approximate transmitter distance. The app can also perform on-device live transcription and translation of received audio.

Alphonse says the app collects no data and contains no ads or tracking. The current release is version 1.3, and he has put together a short 90-second demonstration for anyone interested in seeing it in action:

I haven’t had a chance to try Demod myself yet, so consider this an announcement rather than a review—but it certainly looks like an intriguing tool for SWLs, particularly those who enjoy exploring remote receivers. I do plan to take it for a spin soon!
