PROJECT ECHO - 960-MEGACYCLE, 10-KILOWATT TRANSMITTER

Abstract

Open-ended Terms: ECHO Project. A 10-kw transmitter operating at 960 to 961 mc was used at the eastern terminus of the Project Echo communications experiment. This transmitter is located on Crawford's Hill near Holmdel, New Jersey. The 10-kw output feeds into a waveguide line leading to a 60-foot dish antenna. Exciter-driver units are available to drive the power amplifier with various modulations, such as wide-deviation FM, low-index phase modulation, single-sideband or double-sideband modulation with or without carrier, 960.05 or 961.05 mc constant-frequency CW, and radar on-off pulses at 961.05 mc. The main output amplifier consists primarily of a four-stage, externally-tuned-cavity, water-cooled klystron, operating at a beam voltage of 16 to 18 kv. The transmitter was operated during many Moonbounce, tropospheric scatter, and Echo I tests with very satisfactory results. (Author)
