The Mighty KBC is moving their regular Sunday (00:00 to 02:00 UTC) Giant Jukebox broadcast from 9,450 to 7,375 kHz on Sunday, March 3rd, 2013.
The new broadcast will come from Nauen, Germany, packing 125 kW. The KBC noted that they may move back to the 31 meter band for the summer period.
We will post updates when available.

We will try some fast text modes this weekend on The Mighty KBC, to see if they can survive the rigours of shortwave.
This will be during the North America broadcast at 0000-0200 UTC 20 January on 9450 khz. At about 0130 UTC, 4XPSK63R will be 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 0200 UTC, MT63-2000 (long interleave) will be centered on 1500 Hz, and PSKR250 on 2800 Hz. This will be an Flmsg formatted transmission, with html. Fldigi and Flmsg can be downloaded from www.w1hkj.com.
The Mighty KBC will be doing special broadcasts to test modulation on 6,150 kHz. They will broadcast old shows of The Giant Jukebox. Here is the schedule with dates/times in UTC:
Mail your reception reports to [email protected]
Caution: Don’t try this test if you’re driving an 18-wheeler!
The Mighty KBC is repeating the digital test they broadcast last weekend.
If you tune in (9,450 kHz, from 00:00-02:00 UTC) you should try decoding their digital message. If you configure FLDIGI according to their instructions, below, their broadcast should automatically launch your web browser with a message:
Because shortwave reception conditions were poor in many parts of the world last weekend, we will repeat the same digital text transmissions this weekend on The Mighty KBC.
These will be during the broadcast Sunday at 0000 to 0200 UTC (Saturday 7 to 9 pm Eastern Time in North America) on 9450 kHz. At about 0130 UTC, MT63-1000 will be centered at 1000 Hz, and PSKR125 will be centered at 2200 Hz. At just before 0200, MT63-2000 will be centered at 1500 Hz. Both MT63 modes will use long interleave.
Install both Fldigi and Flmsg from www.w1hkj.com.
In Fldigi, go to Configure > Modems > MT-63 > check 64-bit (long) interleave, 8-bit extended characters, and Allow manual tuning. Also, go to Configure > Misc > NBEMS > check Open with flmsg and Open in browser and, below that, indicate where your flmsg.exe file is located. If everything works, a shortwave transmitter in Bulgaria will open a new window of your web browser.

The Mighty KBC has announced that they’re going to broadcast in DRM again on the 22, 23, 25 & 26 of December from 16:00 – 18:00 UTC. This is in addition to their previous announced December specials. The DRM broadcasts will come from a 100 kW transmitter and curtain antenna in Kostinbrod (Sofia) Bulgaria on 9,755 kHz DRM.
Tune in and let us know if you heard The Mighty KBC in DRM.
As 
DRMNA.info says:
“Let Dr. Elliott take control of your PC!”
I agree.
On several occasions now, Dr. Kim Elliott has transmitted digital messages via shortwave radio in an assortment of digital modes. We’ve mentioned this in the past (and we even posted a tutorial on decoding his WBCQ message).
Early Sunday morning (UTC–Saturday night for many) The Mighty KBC will once again broadcast some of Elliott’s digital messages from 00:00-02:00 UTC on 9,450 kHz. This time, they’ll even broadcast two different messages in two different modes simultaneously (details below). No Johnny, this isn’t your granfather’s shortwave:

The Mighty KBC, 21 Nov 2012: “This UTC Sunday, 25 November, more digital text during the broadcast of The Mighty KBC at 0000 to 0200 on 9450 kHz. At about 0130 UTC, PSK125 will be centered at 1300 Hz on the waterfall, MFSK32 at 2200 Hz. Decode one from the radio, and the other from your recording. Just before 0200, only one mode, MFSK32, will be transmitted, centered at 1500 Hz. For this message, please have Fldigi and Flmsg (both available from www.w1hkj.com), as well as your web browser, all running on your PC. If all goes well, at the end of this transmission, the message should pop up in new windows of Flmsg and your browser. (In Flmsg, click Configure, then Misc, then NBEMS, then check Open with flmsg and check Open in browser.)
[Elliott’s comments] “UTC Sunday 25 November at 0000 to 0200 UTC is the same as Saturday evening, 24 November, 7 to 9 pm Eastern Time in North America. This transmission on 9450 kHz is via a leased transmitter in Bulgaria.
To decode the two text transmissions, download Fldigi and Flmsg from w1hkj.com. Configure Fldigi to work with your PC’s sound card.
Also, in Fldigi, click Configure, Misc, NBEMS. Under NBEMS data file interface, click Enable. Under reception of flmsg file, click Open with flmsg and Open in browser.
During reception, patch audio from the earphone or line out jack of your radio to the microphone input of your PC. You may have to experiment a bit with audio settings. You should see a “waterfall” on your Fldigi display.
If all goes according to plan, when the text message just before 0200 UTC (9 pm Eastern) is completely received, it should pop up in a new window of your default web browser.
By the way, if you haven’t noticed, I’m a big fan of The Mighty KBC. Not only do they broadcast an excellent mix of music on shortwave radio, but they’ll also blast these digital messages to their listeners. Thanks, KBC!
Again, please comment if you decode these messages!
