TEN-TEC and ELECTRO-VOICE CO-FOUNDER AL KAHN, K4FW, SK

Albert R. "Al" Kahn, K4FW, of Cassopolis, Michigan, died on June 15, 2005 at age 98. An ARRL member, Kahn--with Jack Burchfield, K4JU, co-founded Ten-Tec following his retirement from Electro-Voice (E-V), which he'd also founded and served as president. Kahn continued his regular CW schedules until just a few days before he died.

"It's a sad day, but few of us will leave the sort of footprints that Al did during his long and productive life," remarked ARRL CEO David Sumner, K1ZZ. Ten-Tec, on its Web site, acknowledged Kahn's passing "with the deepest regret." Kahn had remained a member of Ten-Tec's Board of Directors.

Kahn's daughter Carol Bieneman says that radio and sound communication fascinated her father from childhood. "At age 12 he joined a Boy Scout troop and was sent home with a radio to repair," she recounts. "This was the start of his lifelong passion for radio."

Born in LaSalle, Illinois, Kahn moved as a child to South Bend, Indiana. He became licensed there in 1921 as 9BBI and later held W8DUS in Michigan. As Burchfield tells it, Kahn (with Lou Burroughs, a local machinist) in 1927 started a radio service shop in South Bend. Legendary Notre Dame football coach Knute Rockne needed a public address system to amplify his voice during practice sessions, and he came to Kahn for help.

Most microphones of the day were carbon-button types, but Kahn constructed a superior velocity--or ribbon--microphone and put together a PA system that Rockne called his "electric voice." In 1930, Kahn and Burroughs adopted the name Electro-Voice for the business and began making velocity microphones, which they also supplied to the military during World War II. During the war, Kahn invented and patented a noise-canceling microphone and marketed it successfully to the military. The design is still in use.

E-V added "high-fidelity" equipment and speakers to its product line, and, in 1960, the company built two plants in Tennessee and shifted operations there from the Midwest. Kahn was president of E-V until 1969 when it merged with Gulton Industries. After departing E-V, Kahn and Burchfield founded equipment manufacturer Ten-Tec, now in its 37th year of manufacturing HF radio equipment for Amateur Radio, commercial, and military applications.

Kahn accumulated many honors over his more than eight decades as a radio amateur and industry figure. He was inducted into the CQ Amateur Radio Hall of Fame and was a member of the First-Class CW Operators Club (FOC), the Old Old Timer's Club, the Quarter Century Wireless Association (QCWA), and the A-1 Operator Club. In 2002, the QCWA honored Kahn on his 80th anniversary as an amateur licensee. He also received an Army/Navy "E" Award in 1945 for supplying the War Department with thousands of microphones during World War II. The Boy Scouts of America presented Kahn with its Silver Beaver Award for staffing Amateur Radio stations at international scout jamborees.
