This manual is not in Warfield's resume. It was printed with the corporate author, Wilcox Elec. Co. on the title page. Warfield says he did not write it, although it is possible he wrote parts of it. It is saved in the Warfield papers files chiefly as a companion paper to the articles which were written and published during the Wilcox electric period. The manual contains photographs of the radio (VHF transceiver) built by Wilcox Electric under Warfield's supervision. The manual is divided into seven separately numbered segments: I) Introduction; II) Installation; III) Operation; IV) Theory of Operation; V) Preventive and Corrective Maintenance; VI) Parts list; VII) Diagrams. This radio was by far the biggest contract which Wilcox had in 1964. Nearly everybody in the company was working on it. Wilcox had a contract to deliver a certain number of radios (to the Army for installation in the C-5 transport aircraft) by a certain deadline. Wilcox had won the contract in a low bid, because they had assumed that all they had to do was use the already existing radio design produced at Collins Radio, in Iowa, a design thought to be in the public domain. However after getting the contract, Wilcox discovered that the Collins design was not in the public domain, and therefore Wilcox Company had to design and produce the radio on its own, with first deliveries due within a year. So this was when they hired Warfield. Warfield worked a sabbatical year at Wilcox helping to design, manufacture, and test this radio. It was during this period that he took part in the only patentable work that he did in his career, the two patents being assigned to Wilcox Electric, and listed in Warfield's resume. The year after the new Wilcox radio was delivered the company's sales had tripled. Mr. Wilcox sold the company to Melpar based on the possession of that radio design. Melpar, and later E-Systems which bought Melpar, continued to produce it for the Army and other customers for years. Mr. Wilcox took the money and retired.
