City officials in Plano (Tex.) are complaining that their radio-controlled lawn sprinkler system is being disrupted by a new public safety radio system 30 miles away. The Southwest Regional Communications Center installed the new radio system to link Cedar Hill, DeSoto and Duncanville, all suburbs of Dallas. The trouble started in early June when Plano gardeners noticed that trees and grass were dying, and then discovered that watering schedules for the $5 million sprinkler system weren't being followed. The Kenwood radio system uses 3-towers, 15-channels and 600 radios in trunked mode, operating on an unusual MPT1327 protocol in the 453/460 MHz band.
