Howard Mills W3HM
Master Craftsman of Collins and Vintage Military Receiver Restoration — Harpers Ferry, West Virginia

A Boatanchor Legends tribute to Howard Mills W3HM — the man whose name on a restoration certificate transformed a radio from a piece of vintage hardware into an instrument restored to the standard its original manufacturers intended. For decades, owners of Collins A-Line, S-Line, 51J-series, R-390/R-390A, Hammarlund SP-600, AR-88, and related receivers shipped their most valued equipment to Harpers Ferry, West Virginia, knowing they would get it back in better condition than it had been since it left the factory.

“There are restorers who fix radios. And then there is Howard Mills, who restores them — completely, correctly, with the full understanding that the radio deserves to be exactly what it was designed to be. When a W3HM radio lands on your bench, you are not looking at a repaired radio. You are looking at a radio that has been given its life back.”

Mike Peace VK6ADA — r-390a.net Administrator

Howard Mills W3HM of Harpers Ferry, West Virginia, was for decades among the most respected vintage radio restoration craftsmen in the United States — a practitioner whose expertise spanned the complete spectrum of mid-century Collins and military communications equipment from the smallest Johnson Ranger to the massive Collins 20V-2 transmitter, and whose reputation for meticulous, complete restoration made the simple notation “W3HM Restoration” on a documentation folder one of the most trusted quality certifications in the vintage radio market.

His focus was the category of equipment that this site is built around: the Collins A-Line (31V, 32V series transmitters), the S-Line (75S, 32S, KWM-2 family), the 51J-series communications receivers, the R-390 and R-390A military receivers, the Hammarlund SP-600, the RCA/GE/Capehart contract variants, the AR-88 series, and the Eddystone professional receivers. Not every restorer who attempts this equipment succeeds; Howard Mills succeeded at a level that very few have matched.

The Collins Collectors Association listed him as the go-to authority for A-Line repair and restoration, and a review of community forums from the late 1990s through the 2010s reveals a sustained pattern of operators sending their most treasured equipment to Harpers Ferry and receiving it back transformed. In 2020 he began winding down his commercial restoration services after decades of work, closing a chapter in the community’s access to his extraordinary skill. This tribute is offered in recognition of what that skill meant to the receivers that passed through his hands — and to the people who own them today.

Section 1 — The Workshop at Harpers Ferry

A visit to Howard Mills’ restoration workshop was, by the accounts of those who made the journey, an experience that stayed with the visitor. The basement of his home in rural West Virginia — approximately equidistant between Harpers Ferry and Shepherdstown, about an hour west of Washington DC via Route 270 to Frederick and then Route 15 and 340 — was less a workshop than a working museum of the finest vintage communications equipment in operating condition.

In racks along the walls: specialised Beckman 51J-4 receivers. SP-600 variants. AR-88 series receivers. R-390 and R-390A units from multiple contractors, in various stages of restoration. Eddystone professional receivers alongside their American counterparts. Equipment that most collectors had never seen in person, let alone in the operating condition that Howard maintained it. On workbenches, units were in active restoration — disassembled with precision, components laid out, each stage receiving the documented, systematic attention that distinguished his work from rushed repairs.

“Inside, you find a wonderland of receivers. You name it, Howard has it. In racks, there are specialised Beckman 51J-4s, SP-600s, AR-88s and R-390/As, Eddystones, and others. In another room, you see some of the most beautiful, and collectible and valuable, American and foreign-made radios dating back to the earliest days. On tables in one portion of the basement, you find several R-390s in various stages of refurbishment. One, he notes (probably among his “keepers”) was found still new in its original crate.” Dan Robinson — SWLing Post Guest Report, October 2015

The reference to the R-390 found new in its original crate has become something of a legend in the community. For those who have spent years searching for a clean, unmodified R-390, the idea of Howard sitting on a crate-fresh example is one of those details that perfectly captures the depth of his access to the equipment he worked on. He did not just restore radios; he lived among them, in a collection that served as his reference library for what these instruments were supposed to look and sound like when correct.

Outside the house: long wires, beams, and antennas that supported both his amateur radio activities (W3HM had been a licensed amateur operator for over fifty years) and his receiver testing. Every radio that left Howard’s workshop had been tested on actual HF signals from a real antenna, not just at the bench. That was part of what a W3HM restoration meant: the radio had been operated, not just aligned.

Section 2 — The Scope of W3HM Restoration Work

What distinguished Howard Mills’ restoration practice from most vintage radio service was its completeness. Many restorers address electrical faults, replace failed components, realign, and return the equipment. Howard’s approach — as documented on his eHam service listing and confirmed by customers across multiple decades — addressed the radio as a whole: electrical, mechanical, and cosmetic.

  • ELEC
    REST
    Complete Electrical Restoration — Component by Component

    Howard’s electrical restorations were not recap-and-align jobs. They were systematic, documented examinations of every active and passive component, with replacements driven by measurement and by the service manual’s intent rather than by a generic parts list. On an R-390A, this meant the complete sequence documented in the community restoration literature: bleeder network verification, mechanical filter insertion loss testing, oscillator deck service, IF transformer inspection, tube testing with documented results, and alignment to TM-11 specification using calibrated test equipment.

    The precision was documented. A W3HM restoration typically came with a folder of paperwork: the pre-restoration condition assessment, the list of components replaced and why, the alignment readings before and after, and the final performance verification. Collectors who purchased W3HM-restored equipment at auction or from estates in later years often found these folders intact — a complete record of what had been done and when, sometimes including receipts totalling thousands of dollars for parts and labour on major units.

  • COS
    MET
    Cosmetic Restoration — Sandblasting, Powder Coating, Silk Screening

    This is the dimension of Howard’s work that most differentiates it from the community standard. Most vintage radio restorers treat cosmetics as secondary — a clean chassis, perhaps a repainted front panel, but not the kind of full cosmetic attention that returns a radio to its factory appearance. Howard offered sandblasting of front panels, powder coating of chassis metalwork to the original colour and texture specifications, and silk screening of dial markings and panel legends to the original appearance.

    The result was that a W3HM-restored Collins 51J-4 or R-390A did not look like a restored radio; it looked like a new one. A customer who received a W3HM restoration of a unit they described as a “junkyard dog radio” reported having to do a double-take on receiving it because the receiver looked new inside and out. This cosmetic standard required not just skill but access to period-correct powder coat colours, correct silk-screening materials, and the understanding of what “correct” appearance looked like for each specific production variant. Howard had all of these.

  • COLL
    INS
    Collins A-Line and S-Line — The Flagship Work

    Howard Mills was listed by the Collins Collectors Association specifically for A-Line repair and restoration, covering the 31V and 32V series transmitters and the J-series receivers (51J-1 through 51J-4). The A-Line equipment is among the most complex and valuable Collins hardware; a 32V-2 transmitter in W3HM-restored condition was considered by the community to represent the practical ceiling of what a restored A-Line station could be. Community members on the Collins reflector consistently described his work on these units as producing performance comparable to a professionally restored EAC R-390A — the highest receiver-quality reference in the community.

    His S-Line work (75S-3 series receivers, 32S-3 transmitters, KWM-2/2A transceivers) was similarly regarded as the standard against which other S-Line restorations were measured. The breadth of his S-Line knowledge — covering the complete production history from the earliest KWM-2 through the final KWM-2A production runs, including the service bulletins and production changes — was of a depth that only came from decades of hands-on work with every variant.

  • R390
    MIL
    R-390/R-390A — Reference-Quality Military Receiver Restoration

    Howard’s R-390 and R-390A restorations were among his most celebrated work. The SWLing Post 2015 visit documented multiple R-390s in active restoration on his workbenches, representing units from different contract manufacturers in various stages of the restoration sequence. The Capehart R-390A described in that visit — refurbished in 2007 and placed in a custom cabinet with an easy-remove top cover — was described by its owner as “one of the most beautiful R-390s I have ever seen.”

    The R-390A restoration community’s highest-quality benchmark is the EAC (Electronic Associates Corporation) contract unit, considered by many to represent the finest production build quality. A W3HM restoration of any contractor’s R-390A was described in community correspondence as performing “comparably in sensitivity to a restored EAC R-390A” — which means the restoration brought the unit to its mechanical and electrical specification ceiling regardless of the original contractor’s build quality variation.

  • SP6
    AR8
    Hammarlund SP-600, AR-88, and Professional Receivers

    Howard’s work was not limited to Collins equipment. His workshop housed multiple SP-600 variants in various configurations, and the AR-88 (a landmark British/American military receiver produced by RCA under military contract) was among his regular restoration subjects. His approach to the SP-600’s unique mechanical challenges — including the preselector variable capacitor rotor bearing contact that the vk6ada.com.au SP-600 Failure Prevention Kit identifies as the receiver’s primary failure mode — reflected the same depth of variant-specific knowledge he applied to Collins equipment.

    He also worked on Eddystone professional receivers, representing the British professional communications tradition, and on the broader spectrum of vintage HF receivers that make up the community of serious boatanchor collectors. The constant thread was the same: bring the instrument back to what it was, not to what was convenient.

Section 3 — The W3HM Certification: What It Meant in the Market

In a community of collectors where provenance and restoration quality are significant determinants of a radio’s value, Howard Mills’ name became a quality certification in its own right. A Collins 32V-2 with a “W3HM Radio Labs Restoration” documentation folder in the cabinet attracted buyers at a premium that reflected the confidence the community had in his work. An R-390A or SP-600 with documented W3HM restoration history was a different proposition from an otherwise identical unit with an unknown restoration background.

This is not a small thing in the vintage radio market. The difference between a correctly restored R-390A and one that has been partially recapped and superficially aligned is the difference between an instrument that meets its TM-11 specifications and one that approximates them. Howard’s documentation standard — pre-restoration assessment, component replacement records, alignment before-and-after, performance verification — meant that a buyer could verify exactly what had been done and what the radio was capable of.

“Howard Mills does a top-rate job on complete restoration of the rigs we all know and love (i.e., 51Jx, 75Ax, 32-Vx, etc.) He’ll make your ‘junkyard dog radio’ look like new.” Collins Reflector, January 2002 — customer testimonial

The W3HM documentation folder has turned up in estates and collections long after the original restoration was completed. A Collins 32V-2 sold at auction by XH Radio Labs in Denver included Howard’s complete restoration documentation from 2011, describing work that had cost thousands of dollars and that had been preserved with the radio for over a decade by a collector who understood what that folder represented. That the documentation survived the collector’s passing and remained with the radio reflects the value the community assigned to Howard’s certification of the work.

The Backlog as Evidence of Reputation

The most telling indicator of Howard Mills’ standing in the community was the wait for his services. His backlog extended to months — sometimes considerably more. This was not a sign of poor organisation; it was the direct consequence of national demand for the work of someone who was, in the words of one community description, “one of the few persons remaining in this country capable of going through classic tube receivers from top to bottom.” Collectors who understood what that meant sent their most valued radios to Harpers Ferry and waited, knowing the result would justify the patience.

Community forum discussions noted that Howard made the lead time completely clear before accepting equipment. If you gave him one of your radios, you agreed that it would be with him for as long as it took to do the work correctly. No shortcuts. No acceptable-but-not-right results. The backlog was the price of genuine quality, and the community consistently judged it worth paying.

Section 4 — Howard Mills in the Wider Community

Howard Mills W3HM and Chuck Rippel WA4HHG (whose Boatanchor Legends tribute is at vk6ada.com.au/chuck-rippel/) occupied parallel positions in the vintage radio restoration community — both nationally recognised, both trusted with the community’s most valuable equipment, both focused on Collins and military receiver restoration, both ultimately stepping back from active commercial restoration work in the 2010s and 2020s. They are mentioned together in community discussions so frequently that their names have become shorthand for “the best available restoration expertise in the US” for this category of equipment.

The parallel is not just biographical. Both men represented a model of restoration knowledge that accumulated through decades of hands-on work with every variant of the equipment rather than through book learning alone. Both had collections that served as working reference libraries. Both developed a level of variant-specific knowledge — knowing which contract year of a 32V-2 had a specific wiring change, or which batch of IF transformers in the R-390A showed a particular failure pattern — that comes only from having opened, assessed, and restored hundreds of examples of the same instrument.

Where Howard Mills and Chuck Rippel differed: Chuck Rippel’s lasting contribution was also documentary — r390a.com, the restoration sequencing guides, the contract year identification materials that the community uses today. Howard Mills’ contribution was primarily in the radios themselves: in the instruments restored to specification that now sit in collections across the United States as physical evidence of what the equipment was designed to be. His work was documented in restoration folders rather than in published guides, and it is preserved in the condition of the radios that carry his name rather than in articles that can be read online. Both forms of contribution matter; they are different.

Section 5 — 2020: Winding Down, and What It Means

In early 2020, Howard Mills W3HM began winding down his commercial restoration services — selling equipment, reducing the active work queue, and stepping back from the role he had filled for decades as the go-to authority for the most complex vintage radio restorations in the United States. The community noticed. Forum discussions that had for years included references to Howard as “still accepting work” shifted to the past tense.

The significance of this transition extends beyond any individual collector’s ability to source a restoration. Howard Mills represented a category of practitioner — the master craftsman who had accumulated deep enough expertise across enough specific equipment variants to restore any of them to original specification — that does not easily reproduce. His knowledge was accumulated over decades of hands-on work with hundreds of individual instruments, calibrated against reference-condition equipment in his own collection. That knowledge does not transfer to a new generation of restorers simply by being written down, though the documentation he left with each restoration helps preserve what he accomplished for the radios that will outlast any individual restorer.

The vintage radio restoration community is a community of passage: each generation of deeply skilled practitioners eventually steps back, and the community works to ensure that what they knew is not lost. For Howard Mills, the preservation is in the radios: in every W3HM-documented Collins 32V-2, 51J-4, or R-390A that continues to operate at its original specification in a collection somewhere in North America, still carrying the folder that documents what was done, when, and by whom.

The legacy in the market. As of 2026, W3HM-restored equipment continues to command premium recognition among informed buyers. A Collins A-Line transmitter or receiver with W3HM documentation is a different proposition from an unprovenanced unit regardless of apparent cosmetic condition. The community’s collective knowledge of what Howard’s work represented means that his name on a restoration folder continues to communicate what it always has: this radio was done correctly, completely, and to the standard the original manufacturer intended.

Section 6 — Legacy

Howard Mills W3HM’s legacy is in the radios. It is in the R-390A with the custom cabinet and the easy-off top cover that one collector described as “one of the most beautiful R-390s I have ever seen.” It is in the Collins 51J-4 that another collector described as looking like new “inside and out” after arriving as a rough unit and performing at the level of a freshly built EAC R-390A. It is in the 32V-2 that a deceased collector had been planning to donate to a museum, W3HM documentation folder intact, representing thousands of dollars of skilled labour applied with the understanding that this transmitter was worth doing correctly.

His legacy is also in the standard he set. The vintage radio restoration community’s expectations for what a “complete restoration” means — electrical, mechanical, cosmetic, documented — were shaped in part by what Howard Mills demonstrated was possible. Collectors who knew his work understood that a radio could look and perform as it had the day it left the factory, not just approximately. That understanding raises the bar for everyone who works on these instruments.

The Boatanchor Legends series at vk6ada.com.au exists to document the people whose contribution to the community of vintage radio collectors and restorers extends beyond their own immediate circle. Howard Mills W3HM belongs in this series not because of publications or analytical papers or community forums, but because of something rarer: he demonstrated, across decades and hundreds of instruments, what it means to restore a radio with the full respect its design deserves.
