VOA Radiogram, 7-8 September 2013: Fldigi, Flmsg, Flamp, RSIDs, MFSK

VOA Radiogram for the weekend of 7-8 September 2013 will include more experiments with RSIDs, the brief signals that automatically switch your decoding software to the correct mode.

For best results, please install Fldigi 3.21.75 from w1hkj.com. When you have 3.21.75 installed, go to Configure > ID > RsID, and adjust Errors to 0 (zero). This will prevent Fldigi from flipping to another mode while decoding our MFSK transmissions. For more information about this, seewww.w1hkj.com/FldigiHelp-3.21/ConfigID.html

Please also download the latest versions of Flmsg and Flamp (2.1.00) from w1hkj.com.

This weekend’s VOA Radiogram will include another transmission in MFSK128. This will be done mainly to see if the RSID works. However, to improve the chances for a successful decode of the very fast MFSK128, it will be in Flamp format. A paragraph will be divided into seven blocks of 64 characters each. And it will be transmitted three times, with the second and third passes filling in any blocks with incorrect checksums. Make sure Flamp is running before the MFSK128 transmission begins; it does not turn on automatically like Flmsg.

The foreign language for the weekend will be Spanish, with brief VOA news items in both plain text and Flmsg formatted. Please turn off and restart Fldigi before each of this weekend’s VOA Radiogram broadcasts to ensure the accented Spanish letters display correctly. You will need the UTF-8 character set. The adjustment can be found via Configure > Colors & Fonts.

In the Flmsg-formatted Spanish news story, you will see several html codes such as í for the accented characters. They might look like decoding errors, but the story should look OK when the web page renders.

To make Flmsg work with Fldigi, in Fldigi: Configure > Misc > NBEMS — Under Reception of flmsg files, check both boxes, and under that indicate where your Flmsg.exe file is located.

Shortwave Radio Recordings: Voice of Greece

1 Reply

Lately, the Voice of Greece has been playing very long sets of music; and not all of it Greek. I assume the break in format has to do with the reorganization of Greek national broadcasting.

I believe VoG could be cut without notice. With heavy budget cuts being dealt to national broadcasting, I doubt investment in shortwave radio will continue since they no longer even have an English language service. This is one of the reasons I’ve devoted a lot of recording time to VoG as of late. Admittedly, I certainly hope I’m wrong about my prediction.

On September 1st, I recorded over five hours of VoG, starting around 22:00 UTC. After about an hour of Greek commentary, you’ll hear music ranging from contemporary to classical.

Pirate Radio Recordings: BOCHF Radio (Boards of Canada HF)

Just last night, I came across a new shortwave pirate radio station: BOCHF.

BOCHF started broadcasting around 23:10 UTC on 6,925 kHz USB, and after about a twenty-five minute set, took a five minute break, then returned with a forty-two minute set, ending with an SSTV QSL. The signal, as you can hear below, is fairly strong, but interference was also strong at times; especially from SSB pescadores (fishermen) and the usual summer static crashes.

The entire mix consisted of Boards of Canada music from Tomorrow’s Harvest. There were no vocal ID’s, but there were messages in CW (Morse code) which clearly identifies this pirate as BOCHF.

The artists Boards of Canada have always had an affinity with shortwave radio, so I find a shortwave pirate station playing their music to be an appropriate tribute. Due to sound card problems, I was unable to decode the SSTV QSL, but thankfully a great copy was posted on HF Underground’s pirate radio forum (see above) by forum contributor, Chris Smolinski.

As I mentioned yesterday, Labor Day weekend is a great weekend to catch a few pirate stations on shortwave. Happy listening!

RTÉ Radio to broadcast GAA finals via shortwave radio

RTÉ Radio has announced that it will broadcast the GAA All Ireland Hurling Final on Sunday 8 September and the All Ireland Football Final on Sunday 22 September via multiple sources including shortwave radio (frequencies and times below).

RTÉ Radio explains:

“In Africa, where many Irish people live and work, often in relative isolation with poor communications, RTÉ is providing special transmissions on shortwave radio.

[…]These services are part of RTÉ’s continued commitment to Irish people overseas and, over the years, has proven especially popular with those in geographically or technically isolated areas.”

Of course, RTÉ will broadcast both finals via the Internet, local radio and television.

On shortwave, RTÉ will broadcast on multiple frequencies–attempting to target most regions of Africa–so there’s a very good chance you could hear one.

Shortwave frequencies for Africa–September 8 and 22, 2013

Both Finals throw in at 3:30 pm Irish Time (14:30 UTC)

Southern Africa – 7405 kHz (2pm to 6pm)
East Africa – 17725 kHz (2pm to 5pm)
East Africa -11620 kHz (5pm to 6pm)
West Africa – 7505 kHz (2pm to 6pm)

Russian Numbers Station UVB-76: “the most mysterious radio transmission in the world”

2 Replies

James Cook, associate editor, at The Kernal has written an excellent article about the Russian numbers station UVB-76. Those of us who listen to numbers stations are very familiar with this reliable buzzer on 4.625 MHz. Cook writes:

The radio signal that occupies 4625 kHz has reportedly been broadcasting since the late 1970s. The earliest known recording of it is dated 1982. Ever since curious owners of shortwave radios first discovered the signal, it has broadcast a repeating buzzing noise. Every few years, the buzzer stops, and a Russian voice reads a mixture of numbers and Russian names.

A typical message came hours before Christmas day, 1997:

“Ya UVB-76, Ya UVB-76. 180 08 BROMAL 74 27 99 14. Boris, Roman, Olga, Mikhail, Anna, Larisa. 7 4 2 7 9 9 1 4”

Instead of shutting down with the fall of communism in Russia, UVB-76 became even more active. Since the millenium, voice messages have become more and more frequent.
