In 2006, Leighton Piper, who was one of the primary contributors has begun to republish, in PDF format, the original thirteen issues of Signal-GK.
- He also made PDFs of the full issues available here.
Much of the work was done in conjunction with HIWG, though the data in Signal-GK didn't always go through the HIWG approval process before publication.
