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.

Shortwave Radio Recordings: All India Radio – Ravi Shankar

Leave a reply

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?

13 Replies

“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!

Pirate Radio Recordings: Renegade Radio

4 Replies

Friday night (late) I caught Renegade Radio on 6.93 MHz in the upper side band.

Renegade’s signal was consistently clear for unusually noisy conditions, though the station was occasionally plagued with transmitter problems. I did not edit these out in the recording because dead air never exceeded a few minutes. So, if you hear dead air, simply fast-foward a minute or two. Total broadcast exceeds one hour and, near the end, Renegade informs us that his transmitter was getting hot. I’ll bet: I don’t know Renegade’s set-up, but many pirates use modified ham radio transceivers that were never intended for those 100% duty cycles, often at full power. Keeps a pirate warm on a winter night, though!

Shortwave Radio Recordings: All India Radio on the Bonito RadioJet

The Bonito 1102S RadioJet IF receiver

After posting my latest All India Radio recording, SWLing Post reader, Pete, suggested that I check out their broadcasts starting around 21:00 UTC on 11,670 and 9,445 kHz, as they are quite strong into North America. He was right.

On Thursday afternoon, I tuned the Bonito RadioJet to 9,445 kHz, where I was greeted with a strong signal from AIR’s Bengaluru, India, transmitter site (over 8,500 miles from my home). I compared the signal on the RadioJet with that of my trusty WinRadio Excalibur to find that the RadioJet’s audio was somewhat fuller and richer. In situations where AM sync detection is not needed, I may start using the RadioJet for recordings. I’ve been using it strategically over the past few months for DRM reception and digging weak stations out of the static–something I typically don’t record, but probably should, as the RadioJet deserves even more air and recording time!

AllIndiaRadioLogo1 I recorded this AIR broadcast on Thursday January 10th–around 21:30 UTC–on 9.445 MHz. This particular broadcast features news, commentary and the wonderful music I’ve come to expect from All India Radio.
