STF Radio International this weekend via KBC

STFradioLast week, I received an email from STF Radio International, a new venture that broadcasts digital modes over shortwave (similar to VOA Radiograms). I asked for a description of their mission–here’s their reply:

“STF Radio is primarily a narrowcasting project, a means to deliver specialized content to specific audiences in remote locations. And due to the nature of shortwave, we’re inviting the world to listen in.

The (possible) series of special multimedia broadcasts will continue the exploration of new possibilities with aging technology. We are currently preparing a 1-hour program for broadcast later in April. Depending on audience response, there may be additional programs throughout the year.

We will continue running tests leading up to the 1-hour show. The second round of tests will begin soon, with another segment of digital modes confirmed for this weekend on The Mighty KBC, same time/frequency as last weekend.”

If you would like to decode STF Radio International‘s broadcast, tune in The Might KBC on 7,375 kHz, April 6, 2014 from 00:00 – 2:00 UTC (Saturday evening in North America). STF indicates that their broadcast will be between 01:30 – 2:00 UTC.

The latest information about STF Radio broadcasts can be found on their website: http://stfradio.com

The Mighty KBC to remain on 7,375 kHz until May ’14

I’ve just heard from The Mighty KBC that they will not move to their summer frequency of 9,925 kHz until May 2014.

Until then, you will still hear the KBC’s Giant Jukebox show on Sundays (Saturday evening in the Americas) at 00:00 UTC on 7,375 kHz. Note that this only applies to KBC broadcasts to North and South America.

If you’ve never heard The Mighty KBC’s Giant Jukebox, listen to what you’re missing!

Shortwave Radio Recordings: The Mighty KBC

"Dad, that's The Mighty KBC! Turn it up!"

“Dad, that’s The Mighty KBC! Turn it up!”

Sunday at 00:00-02:00 UTC, I tuned to 7,375 kHz to listen to The Mighty KBC. This was the first time I tuned to their winter frequency this season and wasn’t sure how strong their signal would be on a relatively noisy night on the bands.

KBC’s signal was blowtorch strength into North America. It could have been easily received on even the most simple of portable radios.

As we’ve come to expect, the Mighty KBC’s Giant Jukebox of music has a lot of rock-n-roll and Euro-pop variety, spanning the decades; DJ, “Uncle Eric” knows how to entertain and spin the tunes! Uncle Eric includes Kim Elliott’s digital text modes in this broadcast–if you missed the live broadcast, you can even decode the messages from the recording below.

The Mighty KBC’s Giant Jukebox is moving to a new winter frequency

wurlitzerJukeboxI’ve just heard that The Mighty KBC is moving their Giant Jukebox program from 9,925 kHz to 7,375 kHz for the winter listening season. The KBC broadcast will still be scheduled on Sundays from 00:00 – 02:00 UTC.

The Giant Jukebox is an easy catch in North America and well worth tuning in as Eric always spins excellent tunes. For a sample, check out this recording from May 2013.

The Mighty KBC broadcast again early this morning (from 00:00-02:00 UTC) on their new summer frequency of 9,925 kHz. Their signal from Nauen, Germany was packing 125 kW–it was amazingly strong into North America. As we’ve come to expect, the KBC’s Giant Jukebox of music has a lot of rock-n-roll and Euro-pop variety, spanning the decades; DJ, “Uncle Eric” knows how to entertain and spin the tunes!

You’ll notice that Kim Elliott has another installation of digital text modes in this broadcast. Decode these digital modes using Fldigi from www.w1hkj.com. Be sure to check out Dr. Elliott’s VOA Radiogram website for full details about this broadcast.

KBC frequency change for North America

MightyKBCTruckThe Mighty KBC just notified me that they will move from 7,375 kHz to 9,925 kHz on Sunday, May 5th–returning to 7,375 kHz on Sunday, September 1st.

So, starting Sunday, May 5th 2013, you can tune in the Mighty KBC from 00:00 – 02:00 UTC on 9,925 kHz.

VOA Radiogram “soft launch” this weekend

VOARadioGramKudos to VOA research analyst Dr. Kim Andrew Elliott for his remarkable innovation:  VOA Radiograms (i.e., digital text messages sent over shortwave broadcast radio), and for promoting this concept through the Voice of America. His persistance, with support from forward-thinking shortwave broadcasters like WBCQ, WRMI and The Mighty KBC, who have all broadcasted his digital messages, has paid off.  Classic technology meets current in this new communication mode which makes internet disruption absolutely irrelevant, and which is even impervious, to a great degree, to interference.

This weekend, the VOA Radiogram will become a reality:

VOA Radiogram will “soft launch” this weekend. Here is the transmission schedule (all days and times are UTC):

Saturday 1600-1630 17860 kHz

Sunday 0230-0300 5745 kHz (Saturday evening in North America)

Sunday 1300-1330 6095 kHz

Sunday 1930-2000 15670 kHz

All via the IBB Edward R Murrow Transmitting Station in North Carolina.

The digital text modes to be transmitted this weekend on VOA Radiogram are as follows. Each text transmission will be one minute, unless otherwise specified. Asterisk * denotes RSID: if your RxID is on, Fldigi will automatically switch to this mode and audio frequency. The other modes you can decode from your recording.

  1. BPSK31 on 2000 Hz*
  2. QPSK31 on 1000Hz, BPSK31* on 2000 Hz
  3. QPSK31 on 1000Hz*, PSK63F on 1500Hz, BPSK31 on 2000 Hz
  4. QPSK63 on 1000 Hz, PSKR125 on 1500 Hz*, BPSK63 on 2000 Hz
  5. QPSK125 on 1000Hz, PSKR250 on 1500 Hz*, BPSK63 on 2000 Hz
  6. QPSK250 on 800 Hz, PSKR500 on 1500Hz*, BPSK250 on 2200Hz
  7. QPSK500 on 800 Hz, PSKR1000 on 1500 Hz*, BPSK500 on 2200 Hz
  8. PSKR500 on 1000 Hz, PSK63F on 1500 Hz, PSKR125 on 2000 Hz, and PSKR250 on 2500 Hz* (5 min 40 secs).  The latter portions of the PSKR250 and 500 transmissions are formatted for Flmsg. (In Fldigi, Configure > Misc > NBEMS > under Reception of flmsg files, click Open with flmsg and Open in browser, and below that state the location of the flmsg.exe file.)
  9. MFSK32 image on 1500 Hz (54 seconds)

In future weeks, after the “hard launch” of VOA Radiogram, only one mode will be transmitted at one time. This will ensure the highest possible signal-to-noise ratio and the best possible chances for a successful decode.
