Abstract :
Three experimental 150 MHz transmitters, located about Albany, New York, have been slaved to a common synchronizing signal by means of phase-lock techniques and wire lines. By achieving excellent, long term relative stability, routine frequency adjustments and annoying beat frequencies are eliminated. Details and performance of a modular system, which makes available any number up to 11 assigned channels, are discussed.
