Gary Gitzen is one of the credited contributors to “The 21st Century R-390A/URR Technical Reference” — the Y2K Manual — the R-390A community’s definitive technical document. His name appears in the contributor list for Release 3 (July 2009), the most comprehensive edition of the manual, which expanded significantly beyond the original releases to include new chapters on receiver optimization, modifications, and the accumulated practical wisdom of the R-390A restoration community.

The Y2K Manual Project

The Y2K Manual was built on contributions from the R-390A community’s most knowledgeable practitioners. The project, led by principal editor Al Tirevold, WAØHQQ, with co-editors Barry Hauser and Pete Wokoun, KH6GRT, drew on the expertise of more than twenty-five named contributors whose collective knowledge spanned decades of R-390A operation, restoration, and modification. Gary Gitzen’s inclusion in this group reflects a level of technical competence and community engagement that the editorial team recognized and valued.

Release 3 of the Y2K Manual was a substantial expansion of the original document. Where Releases 1 and 2 had focused primarily on correcting and annotating the 1985 Navy technical manual, Release 3 added entirely new chapters covering upgrades, modifications, parts information, and restoration best practices. The improved parts list alone — identified in the Release 3 preface as one of the greatest areas of revision — required detailed knowledge of component specifications, cross-references, and modern substitutes for components that had been out of production for decades. Contributors like Gary Gitzen provided the practical knowledge that made these additions authoritative.

Contributing to the Standard

The significance of contributing to the Y2K Manual cannot be measured by word count alone. The manual became the community’s standard reference — the document that defines how the R-390A is understood, maintained, and restored. Every contributor’s knowledge was filtered through the editorial process and integrated into a coherent whole that serves the community far more effectively than any collection of individual posts or articles could. Gary Gitzen’s contribution to that process helped ensure that the Y2K Manual’s content reflected the breadth and depth of the community’s collective expertise.
