Cecil Acuff was a fixture on the R-390 reflector mailing list for more than two decades, contributing practical wisdom on both the R-390A and R-1051 series receivers. From his station in Gulfport, Mississippi, Cecil engaged with fellow enthusiasts through thousands of posts that spanned the full life of the online R-390 community — from the early days of mailing list culture through to the present era.

Cecil’s hands-on experience with both the R-390 (non-A) and the R-390A gave him a perspective shared by relatively few in the community. While the vast majority of collectors and restorers gravitated toward the R-390A — with its mechanical filters and wider availability — Cecil consistently championed the original R-390 as the superior receiver. This was, and remains, a minority position, but one that Cecil defended with the authority of someone who had spent decades operating and maintaining both variants.

A Voice of the Reflector

The R-390 mailing list, hosted on QTH.net, served as the primary gathering place for enthusiasts of these legendary military receivers. Cecil was among its most prolific and longest-standing contributors. His posts ranged from practical troubleshooting advice to sharing restoration progress, from debating the merits of various modifications to offering encouragement to newcomers attempting their first R-390A overhaul.

Cecil’s presence on the list was part of a golden era of knowledge-sharing that included figures like Nolan Lee, Chuck Rippel, Dallas Lankford, Les Locklear, and many others who collectively built the community’s technical knowledge base. His recollections of the list’s earlier culture — the running jokes, the colorful characters, the technical debates — preserved a sense of institutional memory that newer members could not have experienced firsthand.

The R-390 Advocate

Cecil’s assertion that the original R-390 is superior to the “A” model is a position with genuine technical merit. The R-390 uses hand-wound LC filter circuits rather than the mechanical filters of the R-390A, and many who have operated both receivers describe the non-A as having a smoother, more natural audio quality. The R-390’s greater mechanical complexity and the rarity of the receiver itself mean that fewer operators have had the opportunity to form their own opinion through direct comparison. Cecil was among those who had.

A Farewell to the Bench

In February 2026, Cecil posted what many recognized as a farewell to the reflector — announcing his retirement from active R-390A work while keeping just one Collins R-390 for personal use. His message carried the bittersweet tone of someone stepping back from a lifelong pursuit while still deeply connected to it.

“I sure do miss the list of 20 years ago and some of the crazy stuff… Fair Radio… national bureau of standards… wally… and so many others. 20-25 years goes by pretty quick. Y’all keep them going… they’re worth it!” — Cecil Acuff, K5DL, R-390 Reflector, February 2026

Cecil’s words captured what many in the community already felt — that an era was passing, not just for one operator, but for a generation of hands-on practitioners who had kept these legendary receivers alive through skill, persistence, and genuine passion.
