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.
