GB2RS goes digital

Last December, RSGB newsreaders were informed that some experimental GB2RS news broadcasts were planned for 2006 using digital voice transmissions.

The first of these experiments is due to take place from GX0BAA on Sunday 12 February at 2115UTC on 1,992kHz using USB WinDRM, the successor of HamDREAM software.

DREAM is an open software implementation of Digital Radio Mondiale, or digital radio worldwide, which was developed by the University of Darmstadt in Germany.

It was later modified by Cesco, HB9TLK, to an amateur standard that fits into a narrower 2.5kHz bandwidth. The software can be downloaded for free from the web.

GB2RS newsreaders are invited to contact the GB2RS news manager Gordon Adams, G3LEQ, on 01 565 652 652 if they would like to take part in these experiments.

The regular GB2RS MT63 USB data transmissions continue to go out every Sunday evening at 100wpm using 1kHz bandwidth long interleave on 3,600kHz at 2015UTC, and on 1,992kHz and 5,279kHz at 2045UTC.
