From SolderSmoke: Watching Shortwave Broadcast Stations on the TinySA Spectrum Analyser

Curtain Antennas at VOA Site B: Greenville, North Carolina.

Watching Shortwave Broadcast Stations on the TinySA Spectrum Analyser

by Bill Meara

November 18, 2022 1244 UTC. I was using a TinySA spectrum analyzer to look at noise levels on the 40 meter ham radio band. I also wanted to take a look slightly above the band (in frequency) to see Radio Marti at 7355 kHz. As I was doing this I remembered that Vatican Radio was on the air at 7305 kHz from 1230 UTC to 1245 UTC. So was just going to catch the last moments of that day’s transmissions. Sure enough, I caught it, and watched it disappear from the TinySA screen. See the video below:

Radio Marti continued on. In the morning we can hear the rooster recordings from that station. We are using it to test how well our homebrew Direct Conversion receivers avoid AM detection. In the video I mistakenly said these two transmitters were on the air with 250 megawatts. The correct power is 250 kilowatts. Both transmit from Greenville NC. I think the signal from Vatican Radio is stronger here because they are using a different antenna pattern — Radio Marti is aimed at Cuba.

This reminds me of a cool project I have not yet done: modifying the TinySA to allow the user to listen to the station: https://soldersmoke.blogspot.com/2021/10/how-to-listen-with-your-tinysa.html I notice that Dean KK4DAS (my colleague in DC receiver design) was the only commenter on the blog post describing the TinySA mod. TRGHS. We need to to do this.

Here are the reports showing when Vatican Radio and Radio Marti were on the air on November 18, 2022:

Thank you for sharing this, Bill. I love it! The TinySA is such an affordable and useful workbench tool.

The International Radio Report’s 35th Anniversary!

Leave a reply

Many thanks to SWLing Post contributor, Sheldon Harvey–creator, co-host and co-producer of the International Radio Report–who shares the following announcement:

Almost impossible for me to believe it, but Sunday’s upcoming edition of the International Radio Report on CKUT-FM in Montreal will be our 35th anniversary edition of the program. The first edition of the program aired on Thursday, November 19, 1987, our old time slot. That week in 1987 CKUT was also born, going on the air on 90.3 FM, 7 days a week, 24 hours a day.

International Radio Report is one of only a couple of programs to have been continually on the CKUT schedule since the beginning. Our hosts have changed from time to time over the years, as did our time slot, moving from Thursday afternoons at 2:30 PM Eastern to Sunday mornings at 10:30 AM Eastern.

I’d like to thank everyone who has been a part of the program over the 35 years; the various hosts, the numerous guests, and the support of CKUT for standing behind us and providing us with an outlet to bring our program to the listeners, not just here in Montreal but, literally, around the world.

And, to the listeners, a big thank you to everyone who tunes in, whether Sundays on the radio, through online streaming, downloading the program, or tuning in through our YouTube channel. We thank those who have taken the time to submit stories and material for the program. It’s a great help.

Whether you’ve been with us since the early days, or whether you’ve discovered us and come on-board recently, without an audience and your support, we wouldn’t be here. And a very special thanks to those of you who have supported our program and CKUT over the years through the annual CKUT Funding Drive. It costs money to run a radio station. It certainly doesn’t all happen for free! Our listeners have been most generous over the years, making our 30-minute program one of the most successful programs on CKUT at bringing in funds to support the cause.

So, we hope you will tune in, by whatever means you tune in, on Sunday, November 20th to help us celebrate as we mark our 35th anniversary of the International Radio Report on CKUT 90.3 FM in Montreal.

Book Recommendation: War Diaries – A Radio Amateur

7 Replies

Earlier this week, I learned that my friend Volodymyr (US7IGN) published his book War Diaries: A Radio Amateur in Kyiv on Amazon.com and I immediately purchased and read it.

If you’d like to know what it’s been like for a radio listener and ham radio operator living day-to-day in Kyiv since Russia invaded Ukraine earlier this year, I highly recommend reading War Diaries.

Volodymyr (or Wlod) is a regular here on the SWLing Post and simply amazing fellow. We share a love of playing radio outdoors and were even recently featured on BBC Radio 4. Sadly, due to the nature of living in a war zone, Wlod cannot escape urban RFI/QRM by making journeys into the forest. These days, that would be a very dangerous activity.

Instead, Wlod makes the most out of the blackouts caused by Russian missile attacks: he enjoys the radio quiet conditions to listen to and DX stations across the globe from his small apartment on vintage radios that he’s repaired.

In fact, here’s a most recent longwave scan Wlod shared during a blackout with his vintage Radiotehnika Riga-104:

Since Russia’s invasion began, Wlod’s wife and children have taken refuge in Poland. Radio has been his constant companion and even a source of valuable intel.

In Wlod’s book, you’ll learn what’s it’s been like living in a world with constant air-raid sirens, artillery attacks, and blackouts. You’ll also learn how incredibly resourceful and resilient he and his fellow Ukrainians are in the face of the Putin war machine.

I highly recommend grabbing a copy of War Diaries. It’s available on Amazon.com as an eBook for $5.99 and even as a hard or soft cover print book.
