Many thanks to SWLing Post contributor, Tom (DF5JL), who writes:

Who doesn’t know the mysterious station “The Buzzer” on 4625 kHz – but now it gets even more exciting: Because since today “The Buzzer” has a twin that transmits on 4810 kHz – fully synchronous. And to make to put a scoop on it: location is apparently near Changdu in China.

Thanks for the tip, Tom!

Yes, I noticed that our friend, Tudor Vedeanu, recently posted a recording of the new Buzzer twin on 4810 kHz:

I’m curious if the new Buzzer frequency is being used 100% of the time? Can anyone confirm?

Proposal to suspend Radio Romania International’s shortwave service has been rejected

11 Replies

Many thanks to SWLing Post contributor, Tudor Vedeanu, who shares the following update regarding the threat to RRI’s shortwave service.

Tudor writes:

I contacted MediaSind asking for more details about the suspension of the SW broadcasts at RRI. Liviu Grosu, the general secretary of MediaSind told me this:

“Following the reactions of MediaSind, the members of the Board of Directors rejected the proposal of the president-general director of the SRR, Georgica Severin, regarding the suspension of the shortwave broadcasts.”

Brilliant news, Tudor! Thank you for sharing this and also many thanks for obtaining Liviu Grosu’s approval to post his message here on the SWLing Post.

Readers, if you love RRI’s shortwave service, I believe this would still be a great time to let them know you’re happy they’re on the air! For the English language service, use the following email address: [email protected]

Radio Romania International’s shortwave service under threat

Important: Click here to read our update.

Many thanks to a number of SWLing Post readers who have shared a link to this article on the AGERPRES website.

The article is in Romanian and many are interpreting it as stating that the shortwave services of Radio Romani International have already been cut.

I asked SWLing Post contributor, Tudor Vedeanu, for his interpretation. Tudor replied:

[I]t looks like Georgic? Severin, the President and Director General of Radio Romania, repeatedly announced his intention of ceasing shortwave transmissions, due to the recent budget cuts. I could’t find an official announcement about this, but the press release from MediaSind (the Romanian Journalists Trade Union) is worrisome enough.

Tudor will keep us informed as he learns more about this development.

RRI is one of my favorite broadcasters on shortwave. The Romanian service has amazing music programs and I also enjoy listening to their English and French news reports. If the budget cuts are severe, I suspect it may indeed mark the end of their shortwave service.

If you’d like to share your thoughts or express your concerns, consider dropping the English language service of RRI a note via this email address: [email protected]

Tudor demos his portable Raspberry Pi-powered AirSpy HF+

14 Replies

Many thanks to SWLing Post contributor, Tudor Vedeanu, who has kindly shared details about his portable Raspberry Pi system which now can run the AirSpy HF+ SDR.

Tudor writes:

I bought the RPi to use it as a Spyserver for my Airspy HF+ SDR.

My main radio listening location is a small house located on a hill outside the city and there is no power grid there (it’s a radio heaven!), so everything has to run on batteries and consume as little power as possible.

My first tests showed that the Raspberry Pi works very well as a Spyserver: the CPU usage stays below 40% and the power consumption is low enough to allow it to run for several hours on a regular USB power bank. If I add a 4G internet connection there I could leave the Spyserver running and connect to it remotely from home.

Then I wondered if the Raspberry Pi would be powerful enough to run a SDR client app. All I needed was a portable screen so I bought the official 7” touchscreen for the RPi.

I installed Gqrx, which offers support for the Airspy HF+. I’m happy to say it works better than I expected, even though Gqrx wasn’t designed to work on such a small screen. The CPU usage is higher than in Spyserver mode (70-80%) but the performance is good. Using a 13000 mAh power bank I get about 3.5 hours of radio listening.

I made a video showing how it works:

This is fantastic, Tudor. Thanks for taking the time to put together a video for us. I’ve just ordered the latest Raspberry Pi 3 (Model B+). It has slightly more horsepower than the previous Pi3. Tudor, you’ve inspired me to grab the 7″ touch display as well and try my hand at running the AirSpy HF+ portable.

I’m not sure if the Raspberry Pi 3 will be able to record spectrum without hiccups, but it’s certainly worth a try.

As you tweak your system, please keep us in the loop!

How Tudor enjoys Radio Australia

In response to my recent Radio Australia post, SWLing Post reader, Tudor Vedeanu comments:

“I’ve also enjoyed listening to music on Radio Australia lately. “Saturday Night Country” is currently my favorite show on SW. Here is a recording I made during the weekend:

“And indeed Triple J is very good too. I discovered some nice music from talented people I’ve never heard about in my part of the world.”

Tudor, it appears you (and your pup!) live in a very beautiful part of the world. The Romanian countryside certainly makes for a scenic radio listening backdrop. I, too, am a big fan of Saturday Night Country–great stuff!

Many thanks for sharing!
