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

wurlitzerJukeboxThe 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.

Pirate Radio Recordings: Bust A Nut Radio

You know the proceedure

Bust A Nut Radio‘s AM signal came in fairly strong last night sometime around 5:45 UTC (February 2nd) on 6,940 kHz.

You’ll hear a great variety of music–from classic rock to electronica–complete with originally produced ID’s and bumpers in this pirate radio recording.

Note: This is a recording of a real pirate radio broadcast. If you are easily offended by strong lyrics and offensive music, you should slowly back away.

Pirate Radio Recordings: Red Mercury Labs

CommRadio CR1 is now available for purchase

The CommRadio CR-1

The CommRadio CR-1

You can now purchase the CommRadio CR1 (we recently mentioned) for $500 plus $12 shipping on CommRadio’s website.

Don Moore (N0HDX), founder of CommRadio, placed the following statement on the CR-1 order page:

As the lead designer of the CR-1, I am pleased to offer this new radio to you. It draws on my experience as a kid building Knight Kits, from my paper route earnings through currently owning a classic Drake 2B and a Zenith Transoceanic; my benchmarks for enjoyable, high quality short wave listening. I added a smooth machined aluminum tuning knob and minimized the number of buttons to provide you (and me), an intuitively obvious and enjoyable radio to operate. This radio is solid as a brick, looks cool and sounds great. The tall feet have a purpose besides good-looks: rest your hand on the tabletop to spin the knob and for the bottom- speaker to bounce the sound to you instead of going straight up into up in space. The military ‘black box’ people who visit us see it sitting on the shelf with the bright OLED display and they all say: “I want one!” Well, here it is. Let the CR-1 draw you into the wonderful hobby I’ve enjoyed throughout my life.

I do love the look of this little radio–its simplicity reminds me of the Palstar line of shortwave radios.

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.

 

Mike’s home brewed amplified antenna

In my recent post, The truth about portable amplified shortwave antennas, I argue that small, portable amplified antennas are, by and large, ineffective. The post comments are interesting, however; many readers agree, and some tout the Sony ANT-LP1 as worthy, but Mike made the following comment about his amplified antenna:

The one active antenna that I have been pleased with is one I built myself.  The design was by ON2NLT and uses a ferrite rod, so it is somewhat directional.  Rotating the unit (it is very compact) often allows nulling out noise or interference.  You have to be careful not to crank up the gain too much though, or you will amplify the noise floor.  The link is here

Looks like a fairly simple project.  Thanks, Mike!

Shortwave Radio Recordings: Radio Havana Cuba’s DXers Unlimited

ArnieCoroDXersUnlimitedIf 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.)
