Raytheon Introduces Transistorized Radar Braille knobs, whose distinctive shapes give the user an immediate indication of their function in a darkened wheelhouse, are featured on a new high-power, solid-state X-band radar introduced by Ray-theon Company. J. Leonard Lovett, general mana-ger of Raytheon's Marine Products Operation, said the new Model 2840 radar employs fewer tubes and more transistorized circuits than any radar available for commercial use. He said the solid-state circuits contribute to the new radar's high reliability which surpasses all pub-lished standards in Europe and the United States. Mr. Lovett said the new radar had been developed particularly for high-performance operation aboard smaller coastal and ocean-going vessels, tugs, commercial fishermen and yachts. The new Model 2840 radar is manufactured at Raytheon's South San Francis-co, Calif, plant and qualifies for outfitting public and subsidized vessels and those subject to "Buy America" stipulations. The new radar has a peak power of 20 kilowatts and an average power of 20 watts for effective tar-get acquisition at ranges up to 48 miles. Six-range scales provide coverage up to y2, \ l/z, 3, 6, 12, 24, and 48 nautical miles. The new Raytheon radar system has four units: antenna, indicator, magna-bond The Original ALUMINUM VINYL Coating (Protected by U.S. Patent No. 2.979,416) PLASMA CHEMICAL SYSTEMS, INC.
