I suggest that a search of early TV patents might turn up some of the DuMont engineers that could still be living. These guys might have some insight into what went on. Unfortunately, this stuff would pre-date the cross-indexed computerized patent listings that date from the 70's, so a han search would be necessary. Richard Palmer, who was at Sarnoff Labs a number of years, has been dead twenty-odd years. Dunno who the company's other boy geniuses were. Al Limberg ----- Original Message ----- From: Larry Bloomfield To: Open DTV list ; TV-Tech@xxxxxxxxxxxxx Sent: Friday, December 19, 2008 5:24 PM Subject: [opendtv] DuMont Television I have an associate who is a retired broadcast engineer and is researching the early history of television including the contributions of Dr. Allen B. DuMont and the DuMont Television Network. He says that while Clarke Ingram has done extensive work on the DuMont History, very little has been said about the technical side of the Network. He has questions about what happened to the TV Equipment manufacturing arm of DuMont Laboratories and understands DuMont equipment was used by many early broadcasters with some as a "turnkey" station. He'd sure like a list of those stations. Having lived in Kansas City, Missouri for much of his career, he had an opportunity to visit DuMont's only UHF outlet after it went dark. Actually, all that is left is the original studio space in a downtown building and the transmitter site (now a church) on the Kansas side of the Stateline. He's asked me for his help and now I'm asking for yours. -- Larry Bloomfield, KA6UTC 1980 25th St. Florence, OR 97439 (541) 902-2424 (everything number) www.Tech-Notes.TV See you on the Taste of NAB Road Show
