Experimenting with digital text modes on 9450 kHz

At The Mighty KBC, we have been experimenting with digital text modes during our Sunday 0000-0200 UTC broadcast on 9450 kHz. Text via shortwave can be a useful substitute if the Internet is disrupted or blocked.

To decode the digital text transmissions, we suggest that you download FLDIGI from www.w1hkj.com. Please also download FLMSG, because we will use it on our 25 November broadcast.

On 18 November, the first text transmission at about 0130 UTC will be in three modes simultaneously. On the "waterfall," PSKR125 will be centered at 1000 Hz, DominoEX 16 at 1500 Hz, and MFSK32 at 2000 Hz. Decode one of the modes from your radio, then decode the others from your recording.

Just before 0200 UTC, The Mighty KBC program schedule will be sent as a web page. Two modes will be available: PSKR250 on the left, and MFSK64 on the right. Decode one from the radio, and the other from your recording.
