Digital text this weekend on The Mighty KBC and WRMI

Because of poor propagation in many parts of the world last weekend, The Mighty KBC, via Bulgaria, will repeat last week's digital text transmission. This will be during the KBC broadcast UTC 16 Dec, 0000-0200, on 9450. At about 0130, MT63-1000 (long interleave) will be centered on 1000 Hz, PSKR125 centered on 2200 Hz. Decode one from your radio, decode the other from your recording. At just before 0200, MT63-2000 (long interleave) will be centered on 1500 Hz. This second transmission will be an html-formatted Flmsg message. Download 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. Also, WRMI, 9955, will transmit IDs in digital text modes this weekend. Saturday 0500 to Sunday 0500, the mode will be BPSK63F (also known as PSK63F). Sunday 0500 to Monday 0500, the mode will be Olivia 64-1000 (a non-standard mode that will require a custom setting in Fldigi; unlike most digital modes, this one sounds pleasant). The WRMI IDs are, of course, mostly on the hour and half hour. In Olivia 64-1000, the ID will appear a few seconds after you hear the tones and see the waterfall.
