Carlos Latuff’s shortwave radio logs are a work of art

For those who don’t know, our friend and SWLing Post contributor, Carlos Latuff, is not only a devoted radio enthusiast, but also a prominent political cartoonist in Brazil and throughout the world.

Recently, Carlos has been posting his shortwave logs on his Twitter feed and they’re pretty amazing.

Carlos’ shortwave logs not only include comments and notes from each broadcast, but also his own artwork.

Here’s Carlos’ recording of Vatican Radio which accompanies the log at the top of this post:

Click here to check out Carlos’ Twitter feed where he posts his political cartoons and, yes, even the occasional shortwave listening log!

If you’ve been a reader of the SWLing Post for long, you’ll notice that we’re not a space for political discussions; there are much better options out there on the Internet. Here, we stick to the world of radio, but we can’t help but highlight this intersection and Carlos’ creative logs.

In fact, Carlos, I might nudge you for that Vatican Radio recording and your artwork to post on the Shortwave Radio Audio Archive!

Five Beeps: Can you identify Carlos’ mystery signal?

Many thanks to SWLing Post contributor, Carlos Latuff, who writes from Brazil:

[Please check out this] audio sample of a signal I heard today (July 20, 2021) around 07h17 UTC on (at least) 4 different frequencies, simultaneously:

– 16166 kHz
– 16716 kHz
– 16747 kHz
– 16839 kHz

Always the same. Five beeps repeating in intervals of 30 seconds. 
Another mystery to be solved by your readers.

Thank you for sharing this, Carlos. Hopefully, a reader can comment and ID these beeps for us!

Can you ID these HF transmissions?

Many thanks to SWLing Post contributor, Carlos Latuff, who shares the following video of sounds he heard on HF. Carlos adds, “Are we in the Twilight Zone or Lost in Space? They sound like effects from a 60’s/70’s sci-fi movie!

Those sounds are wild! The stuff of Star Wars.

My only guess is that it’s a form of OTH RADAR? I’m sure an SWLing Post reader will sort this out in short order! Please comment!

Carlos seeks clarity about another CW station

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

Today (June 5, 2021) I heard another mysterious CW transmission here in Rio Grande do Sul coast, this time on 8779 kHz, 18h31 UTC.

I did some research and this frequency is related to Rome Radio (which is no longer transmitting in CW) and a marine channel (ITU821) related to Cape Town Radio but I’m not sure:

I’m sure your readers will solve this puzzle as well.

Thanks for sharing, Carlos!

Radiofax images of Typhoon Surigae from the Japan Meteorological Agency

Many thanks to SWLing Post contributor, Carlos Latuff, who writes:

Technology considered obsolete, the fax, or better, radiofax (transmitted by radio) continues to be used by several meteorological agencies around the world, which broadcast weather charts to vessels on the high seas. These two images were transmitted today by the Japan Meteorological Agency and received at 19h10 and 19h50 (UTC) in Porto Alegre, Brazil.

The first image is a photo from the Japanese satellite Himawari 8. Even with noise, due to the shortwave propagation, you can see clearly the “eye” of typhoon Surigae.

The second image is a typhoon alert, indicating on the map that Surigae has changed course and is now en route to the Pacific.

These two images were transmitted today by the Japan Meteorological Agency, on the frequency of 7795 kHz

Thank you for sharing this, Carlos. It’s amazing, the amount of information you can receive over the air even with modest equipment by today’s standards. With a modest portable radio and a little decoding software, anyone can grab images like this.
