In March the DC Section met in the conference room at NAB Headquarters for a presentation on "Cutting Edge COFDM Microwave Applications." The primary presenter, Daniel Shine, Vice President of Business Development at RF Central, gave an entertaining description of the systems, procedures and techniques used for live coverage of the just-completed 2007 Tour of California bicycle race. Also on hand to answer technical questions was William (Bill) Hurlock, a Senior RF Engineer at Total RF, who had recently returned from the race.

Coverage for the bicycle race involved an elaborate system of motorcycle- and helicopter-mounted cameras and transmitters, circling plane-based repeaters, and extensive ground facilities for reception of the live signals and re-transmission for public distribution. Covering a 600-mile course over eight days, the entire RF operation was moved and re-deployed every day as the race made its way down the coast from San Francisco to Los Angeles. Total RF, a subsidiary of RF Central, provided the technical concept design, operation and logistical support, and developed many of the special transmitters, tracking antennas and other equipment needed for this unusual application. RF Central's CTO, Jim Malone, led the technical design and operational teams for the event.

Many thanks to Graham Jones and the NAB for providing facilities, and Norm Stein of RF Central for refreshments and for bringing the DC Section this interesting program.
