Washington, DC - Feb 22, 2011 - Radio engineering expert L. Robert du Treil of du Treil, Lundin & Rackley (DLR), and Thomas B. Keller, television technology innovator, have been named the 2011 recipients of the National Association of Broadcasters Engineering Achievement Award. They will be honored with the award at the NAB Show Technology Luncheon on April 13.

Du Treil, the Radio Engineering Achievement Award winner, has more than 50 years of experience in all aspects of radio and TV engineering. He is currently a consultant of du Treil, Lundin & Rackley, where he previously served as owner and president. With a reputation as a creative and insightful engineer, du Treil is best known for his contributions to international discussions on mediumwave (AM) directional antenna technology in the early 1980s.

In addition to his consulting work, he has published a number of papers and articles and made presentations to national, state and local broadcast engineering groups over the years that have led to numerous innovations in the field. He is also a member of the Institute of Electrical and Electronic Engineers (IEEE), the Society of Broadcast Engineers (SBE), and the Association of Federal Communications Consulting Engineers (AFCCE), having previously served as president.

Keller, who will receive the Television Engineering Award, has spent more than 50 years working in the U.S. television broadcast industry, contributing significant achievements to broadcast engineering development and emerging as a leading technical innovator. As president of technology consulting firm T. Keller Corporation, he has led development and extensive laboratory and field studies of new technologies for broadcasting. Among his accomplishments, Keller created an early computerized captioning system for the hearing-impaired and engineered one of the first electronic field production programs ever produced for network release.

Keller served as head of the NAB's Science and Technology department in the 1980s, helping establish the Advanced Television Systems Committee (ATSC) and overseeing the Advanced Television Terrestrial Broadcast Project, which provided transmission/reception of early HDTV technologies used for demonstrations to the FCC and Congress. Keller is a Lifetime Fellow of SMPTE and a senior member of the Broadcast Technology Society of the IEEE.

The National Association of Broadcasters established the NAB Engineering Achievement Award in 1959 to recognize an individual's accomplishments and contributions to the broadcast industry. Award winners are recognized as pioneers, innovators and leaders in the field of broadcast engineering.
