Many thanks to SWLing Post contributor, Pete Madtone, who shares the following recording of Cuban Numbers Station HM01 and notes:
I was reading HF Underground earlier and a post on it mentioned that HM01 had gone a bit mad “10345 kHz is HM01 Cuban Lady with what sounds like a cuckoo clock“. Well I got up straight away and tuned in on VE7AV KiwiSDR and here it is in all it’s glory:
It almost sounds a bit reggaeish and even has what sounds like a little drum roll in parts.
If you’re feeling a bit down or tired today please have a listen as this’ll cheer you up!
All the best
Wow–thanks for sharing this recording with us, Pete! What a mystery behind this numbers station! Was the cuckoo intentionally or unintentionally added to the audio at the studio or transmitter level? What could that signify? Since the audio is tracking with the HM01 broadcast, it seems to be originating from the same transmitter.
Perhaps this adds more context or confusion: SWLing Post contributor Paul Walker has noted a number of audio “shenanigans” from Cuban broadcasts. Here are a few notes from his listening post in Alaska:
0320UTC Mon Aug 28 and Cuba is missing from 9700 for the 2nd time in a week, but instead of regular programming they’re broadcasting a horror movie of some kind. I can detect some kind of noise under the movie but it’s like a screech/hum, which is all I heard from 9700 last time it was on.
I should also add, after the first time i heard 9700 down on 9600, I subsequently heard it back on 9700 again…..so something’s up!
And now HM01 aka Suzie Cubana on 10345 is broadcasting……. along with Suzie counting down the numbers and the digital data bursts, theres a cuckoo bird cuckooing over the top of that audio.
In the 0500 UTC, Rebelde on 5025 kHz noted running TV audio too….some English language movie.
The domestic Radio Rebelde AM and FM web feeds appear to be running normal programming
Radio Waves: Stories Making Waves in the World of Radio
Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Since World War I, countries around the world have been broadcasting mysterious numerical messages via shortwave radio. Though concrete evidence is hard to come by, the general consensus is that these coded messages are meant for undercover agents operating abroad. And one particular Russian station may have an even more sinister purpose. Featuring computer engineer Andrus Aaslaid, historian Maris Goldmanis, and documentary photographer Lewis Bush.
A public SDR network triangulates the island as the source of mystery signals
By Stephen Cass
As anti-government protests spilled onto the streets in Cuba on July 11, something strange was happening on the airwaves. Amateur radio operators in the United States found that suddenly parts of the popular 40-meter band were being swamped with grating signals. Florida operators reported the signals were loudest there, enough to make communication with hams in Cuba impossible. Other operators in South America, Africa, and Europe also reported hearing the signal, and triangulation software that anyone with a web browser can try placed the source of the signals as emanating from Cuba.
Cuba has a long history of interfering with broadcast signals, with several commercial radio stations in Florida allowed to operate at higher than normal power levels to combat jamming. But these new mystery signals appeared to be intentionally targeting amateur radio transmissions. A few hours after the protest broke out on the 11th, ham Alex Valladares (W7HU) says he was speaking with a Cuban operator on 7.130 megahertz in the 40-meter band, when their conversation was suddenly overwhelmed with interference. “We moved to 7170, and they jam the frequency there,” he says. Valladares gave up for the night, but the following morning, he says, “I realize that they didn’t turn off those jammers. [Then] we went to 140 the next day and they put jamming in there.”[…]
Houlton School, where Rugby Radio Station once stood, is set take its first influx of pupils in September
Plans for a new school at the historic former home of Rugby Radio Station are being fine-tuned and remain on track for a September start.
Houlton School, which will be named after the town in America that received the first transatlantic voice broadcast from Rugby Radio Station in 1927, will take its first influx of 180 Year 7 pupils this autumn.
The school, which forms part of the 6,200-home urban extension in Houlton, east of Rugby town centre, will take a new year group of 180 pupils every 12 months.
Michael McCulley, the school’s Principal Designate, said: “Whilst building a fantastic £39m new school during three lockdowns has had its challenges, we are also acutely aware that we have had a completely blank page from which to develop our exciting curriculum and pastoral programme.
“This freedom has been important as we have needed to evolve to the changing needs of our first group of students.[…]
Ham Radio Outlet to open store in Florida (Amateur Radio Newsline)
Ham Radio Outlet, the nationwide amateur radio retailer in the US, has announced that its ongoing expansion plans will include a store in the state of Florida. The new store will join 12 already open in such states as California in the West, where the company is based, to Delaware in the East, Arizona and Texas in the South, New Hampshire in the North. The company’s announcement on social media set off a wave of speculation about the new location, especially on Instagram where the company wrote, “We’re not telling yet! We’re open to suggestions.” The closest Ham Radio Outlet to Florida is in Atlanta, Georgia. The company, which calls itself the world’s largest supplier of amateur radio equipment, is also known for shipping internationally.
Every Sunday, an operator with Pune Police’s wireless wing sends a Morse Code message to the office of the Director General of Police, Maharashtra.
IN THE era of satellite communication, which involves transmitting signals into space and back, and internet based systems transferring gigabytes of data in a flash, police have kept alive the age-old system of Morse Code – a primitive method of sending messages in the form of dots and dashes.
Every Sunday, an operator with Pune Police’s wireless wing sends a Morse Code message to the office of the Director General of Police, Maharashtra. While this is their way of paying tributes to one of the earliest modes of telecommunication, it is primarily a way of maintaining a robust stand-by mode of message delivery in case all other means of communication fail.
Pune City police have recently started a series of tweets featuring the communication systems used by the police and their evolution till date. On Sunday, Pune Police Commissioner Amitabh Gupta tweeted, “As an ode to the beginning of wireless communications, the Commissioner’s Office still uses Morse Code to transmit Messages every Sunday.”[…]
ANTIQUES ROADSHOW saw a World War II spy radio which was disguised as a toolbox fetch a huge valuation when it travelled to Kenilworth Castle.
Antiques Roadshow’s expert Mark Smith marvelled at the ingenuity of a spy radio which was used in World War Two in a recent episode. The item, from the outside, was made to look like a toolbox but when opened, displayed a detailed radio which could be “powered by any source”. So how much was it worth? Mark put a £10,000 to £15,000 price tag on it.[…]
Former WNYC director Seymour N. Siegel suggested that WNYC once received fan mail from Einstein. As I continue to look far and wide for evidence of this alleged bit of praise, I can’t help but wonder, what broadcast prompted the great man to write? Alas, so far, the document has eluded me. But, we do know that the father of the theory of relativity was a subscriber to both the WNYC and WQXR program guides. And we have no less than Erwin Panofsky, the noted German-American art historian and friend of Einstein’s, to thank for that.
It all began when the distinguished gang at the Institute for Advanced Study in Princeton, New Jersey decided to chip in and build the Nobel laureate a “high-fidelity” radio for his 70th birthday. The 1949 gift included subscriptions to the WNYC, WQXR, and WABF program guides.[…]

Massive jamming on 40m (possibly from Cuba) is bugging the radio community
Apparently this is going on for a week now on 40m:
Spent last night at my beach listening post on the German North Sea coast and found this fairly strong signal and a 40m band mostly cleared of any other signals. As soon as I found out that it wasn’t something local, I was wondering who’s responsible for this mess again. It looks like Josh (“Ham Radio Crash Course” YouTube channel) may have found a possible origin of that signal:
Here’s what it sounds like on each of the apparently manually controlled jamming channels:
Cuba would’ve probably been my last guess here on the other side of the big pond. 🙂 In other words, they – whoever they are – jam the band for at least half of the world. Luckily 40m isn’t exactly a pleasure in most of the summer anyway but after having to suffer OTH radars, FHSS blips and politically motivated broadcasting with associated jamming on 40m for a long time, this is a new low. I don’t want to get all political here but trying to erect some electromagnetic fence around a country has never really worked out, it’s just a futile, at most temporarily effective and symbolic act, perceived as pointless and aggressive vandalism out of blank despair by the rest of the world.
SWLing Post community: perhaps you can help with an inquiry I recently received. Radio historian, Alejandra Bronfman, writes:
I’m a historian of radio in the Caribbean, and David Goren suggested I contact you with a question about some 1959 broadcasts I’m trying to track down. These were produced by Haitian dissidents Daniel Fignolé and Louis Dejoie; one in Brooklyn, one in Havana, for broadcast over Havana’s Radio Progreso. They started in January 1959 and ended a few months later. I’m not sure whether they were in shortwave format, though I would guess that they were if they were aimed at Haiti as well as the eastern part of Cuba. I’m looking for any sources at all that might help me fill in the story, which I have mostly from some contemporary accounts, newspapers and US-based official sources.
Anyway, please excuse the intrusion and the out-of-the-blue nature of my query. I’m trying to hunt down all possible clues that may lead to more source material.
thanks so much;

If you have any information or leads that could help Professor Bronjman, please comment! Thank you!
Note that the Edward R. Murrow Transmitting Station–the last VOA/BBG transmitting site in the US–is the main provider of Radio Marti over shortwave. No doubt, this proposed cut could close the site permanently. The end of an era.
Trump’s budget includes drastic cuts to Radio and TV Martí
President Donald Trump’s recently released budget would drastically cut funds and staffing at the Miami-based Radio and TV Martí, while restoring funds to support other democracy projects in Cuba and new ones in Venezuela.
The restoration of funds comes amid large cuts to the Department of State and the United States Agency for Development (USAID). The proposal would allocate $10 million for programs related to Cuba and another $9 million for similar initiatives in Venezuela.
Someone recently described my shack in Oxford as ‘an impressive mess’…. and that really is just about the most positive comment I’ve ever received regarding my listening post! So, my apologies for displaying the mess in public, but in response to having been asked many times by subscribers to Oxford Shortwave Log to ‘share my shack’, here it is, well most of it at least, in all it’s unadulterated glory.
The primary reason however for this post is to share my most recent transatlantic medium wave catches using the brilliant Elad FDM DUO and Wellbrook ALA1530 magnetic loop antenna. This excellent combination continues to pull in really nice DX, although not so much very recently as propagation has been fairly rubbish. However, since early to mid December, the dynamic duo have managed to pull in a number of transatlantic medium wave signals, including Radio Rebelde, Cuba on (670 and 710 kHz), KVNS Texas, CHIN Radio, Toronto, WFED Washington DC, WWNN Health and Wealth Radio, Pompano Beach, Florida, and huge signals from WMEX Boston and WWKB Buffalo, New York. Embedded reception videos and text links follow below and in the mean time, I wish you all great DX!
