I’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.
Kudos 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.
- BPSK31 on 2000 Hz*
- QPSK31 on 1000Hz, BPSK31* on 2000 Hz
- QPSK31 on 1000Hz*, PSK63F on 1500Hz, BPSK31 on 2000 Hz
- QPSK63 on 1000 Hz, PSKR125 on 1500 Hz*, BPSK63 on 2000 Hz
- QPSK125 on 1000Hz, PSKR250 on 1500 Hz*, BPSK63 on 2000 Hz
- QPSK250 on 800 Hz, PSKR500 on 1500Hz*, BPSK250 on 2200Hz
- QPSK500 on 800 Hz, PSKR1000 on 1500 Hz*, BPSK500 on 2200 Hz
- 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.)
- 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.

The Mighty KBC will be testing Monday and Tuesday mornings (March 11th & 12th) from 09.00 -11.00 UTC.
They will be on the following frequencies (simultaneously):

The Mighty KBC will be broadcasting the Giant Jukebox this weekend, Sunday (00:00 to 02:00 UTC) on their new 7,375 kHz frequency.
For those of us in North America, this broadcast will be Saturday evening (tonight!) from 19:00-21:00 EST. Last Sunday, March 3rd, 2013, was the KBC’s first broadcast from Nauen, Germany, packing 125 kW.
More of Kim Elliott’s digital text in this broadcast, too–faster modes this time. At about 0130 UTC, MFSK64 will be centered on 1000 Hertz, and PSKR250 on 2000 hertz. At just before 0200 UTC, MFSK32 images will be centered on 800, 1500 and 2300 Hz.

VOA Radiogram is a new Voice of America program experimenting with digital text and images via AM shortwave broadcasting. One might say this is the crossover point between classic shortwave and current technology. It’s fun and fascinating stuff, and also has real utility.
If you’ve been an SWLing Post reader for very long, you’ll be familiar with the digital messages, otherwise known as radiograms, included in broadcasts from The Mighty KBC and, earlier, from WBCQ. We’ve also offered a small primer on decoding.
In the near future, Dr. Kim Elliott’s digital radiograms will be broadcast through VOA via the Edward R. Murrow Transmission Station in Greenville, NC.
The new VOA Radiogram website contains time and frequencies and all of the information you’ll need to decode VOA radiograms.
Incidentally, Kim Elliott and I will be presenting on the topic of VOA Radiograms and digital modes at the 2013 NASWA Winter SWL Fest. If you’re interested, it’s not too late to register! Meanwhile, stay tuned for more information about radiograms.
