Abstract: Inside Ten-Tec — QRP Innovators
This historical feature article, written by J. Tom Badgett (K4MDK) and published in the December 1977 issue of 73 Magazine, documents the origins, philosophy, and manufacturing practices of Ten-Tec, Inc., located in Sevierville, Tennessee.
Founded in 1969 through a collaboration between former Electro-Voice president Al Kahn (K4FW) and design engineer Jack Burchfield (K5JU), Ten-Tec was established with a steadfast commitment to solid-state design and low-power (QRP) amateur radio equipment. The article chronicles the company's early struggles introducing beginner-oriented gear like the Power Mite and Argonaut lines, its eventual commercial breakthrough with the Triton transceiver, and the development of new products such as the Century 21 CW transceiver and digital Triton IV.
Key highlights of the piece include:
Vertical Integration: Detailed descriptions of in-house manufacturing processes, including custom coil-winding machinery, automated transformer lamination, temperature-compensated VFO boards, and mechanical cabinetry production.
Engineering Standards: Strict design protocols yielding low audio distortion, high transistor longevity predictions, and a comprehensive five-year product warranty.
Business Philosophy: A unique blend of modern solid-state technology paired with old-fashioned corporate integrity, customer fairness, and a personal small-company workplace culture.
