Shortwave Radio Recordings: The Giant Jukebox and Kim Elliott’s digital text on The Mighty KBC

wurlitzerJukebox The Mighty KBC’s broadcast from Bulgaria was mighty strong last night into North America. I recorded the full 2 hour show of The Giant Jukebox on 9,450 kHz beginning at 00:00 UTC.

As I’ve come to expect from The Mighty KBC, this show has an marvelous mix of rock-n-roll through the decades along with Eric’s professional DJing. The Mighty KBC has real people behind the music mix, a refreshing alternative to the iHeart Radio and Pandoras of the world.

Of course, this recording includes Kim Elliott’s digital text modes. For those of you who would like to decode it, here are the details:

At about 01:30 into the recording, 4xPSK63R is centered on 1000 Hz and MFSK64 centered on 2000 Hz. (For 4XPSK63R, use Fldigi 3.21.65 or newer: OpMode > PSKR > MultiCarrier > 4XPSK63R.)

At just before the end of the transmission, an image will be transmitted in the MFSK16 mode. Also, MT63-2000 (long interleave) will be centered on 1500 Hz. This will be an Flmsg formatted transmission, with html. Fldigi and Flmsg can be downloaded from www.w1hkj.com.

Please comment if you were able to decode.

As I suspected, the unidentified broadcast I recently posted was the Chinese jamming service, Firedrake. Thanks to all who confirmed.

Mark Fahey even commented with a link to an article explaining how he made a studio recording of Firedrake from Chinasat 6B. Read Mark’s article here.

Mark also has the full 60 minute studio copy of Firedrake available as a 90MB MP3 file.

Shortwave Radio Recordings: All India Radio – Ravi Shankar

Ravi Shankar passed away December 11, 2012. Like many people, Shankar was a complicated fellow, but no one can deny his talent on the Sitar. His music will live with us forever, not to mention through the musical talents of his children, Anoushka Shankar and Norah Jones.

I recorded this clip of him on All India Radio some weeks ago. Click here to download or enjoy below:

Shortwave Radio Recordings: Firedrake?

“Mum, this sounds like Firedrake. Quick, make a note of it in the logs!”

I’ve noticed a broadcaster that routinely transmits weekends at 11:00 UTC on 6,970 kHz. Some mornings, it’s much stronger than others. Saturday morning, my time, I managed to record it in its typical format: music. Specifically, Chinese folk music, at least so it sounds to my untrained ear.

I searched through logs and in the WRTH, and I could find no mention of a broadcaster on 6970 kHz. It doesn’t help that the 27 minute broadcast contained no audible IDs.

So, I’ve come to the conclusion that my initial hunch is correct–that this is the Chinese jamming service, Firedrake. Using Firedrake, the Chinese government transmits music on top of broadcasts they wish to block. It’s fairly effective (and annoying). While I’ve heard Firedrake a number of times over the bands, I can’t say I’ve ever tried to listen to the one-hour production.

The following recording contains a 27 minute broadcast of what I believe may be Firedrake on 6,970 kHz, starting around 11:00 UTC, Saturday January 26, 2013. Click here to download the MP3, or simply listen via the embedded player below. Note that the first two minutes have some digital noises (in the lower side band) that affected my receiver’s AGC.

If you can confirm or correct my supposition, please comment!

Shortwave Radio Recordings: Radio Havana Cuba’s DXers Unlimited

ArnieCoroDXersUnlimited If you live in the Americas and you regularly listen to a shortwave radio, you have no doubt heard Radio Havana Cuba across the shortwave spectrum. When I travel in North or Central America, I can easily hear RHC, often without even extending the telescopic antenna on my portable.

A long-running program on RHC’s English hour is Arnie Coro’s DXers Unlimited.

Tuesday night, I recorded the DXers Unlimited segment from RHC’s The English Hour on 6 MHz, and offer it here for your listening pleasure. If the recording doesn’t sound typical of shortwave radio, it’s because: a) RHC’s signal is exceptionally strong into North America, and b) I recorded this with an AM filter 24 kHz wide. In other words, I widened my DSP filter to match RHC’s bandwidth on my spectrum display–and to put this in perspective, I regularly record between 7-9 kHz wide. (This results in the crisp, high-fidelity audio you hear in this recording, though unfortunately at the compromise of any adjacent stations abiding by HF broadcasting etiquette.)

Thanks, Benn, for sharing this:

Radio continues to be a powerful tool for community information, and the RootIO project amplifies it by mixing its power with new mobile and Internet technologies. RootIO is an open-source tool kit that allows communities to create their own micro radio stations with an inexpensive smartphone and transmitter, and to share, promote, and collaborate on dynamic content. The project will be piloted in Uganda in partnership with the Uganda Radio Network, UNICEF Uganda and UNICEF Innovation Unit.
