Summarised from the Signal-GK The Fanzine Re-issue (v1.0) 10/10/2006 website:
The Signal-GK fanzine was put together in the late 80s/early 90s and ran for thirteen issues. The primary objective was the mapping of a complete sector, Dagudashaag, and the generation of complete Library Data. Each issue concentrated on at least one subsector - later issues covered two subsectors. Together with other articles on Dag and scenarios linked to the sector, it was hoped that SGK would be the most comprehensive resource for any part of the Imperium. Issues were not meant to be version specific, with Classic, MegaTraveller and The New Era rules set covered at some point.
