A high-speed data modem was adapted for operation with a ground-air- ground digital communications link. The modems employ phase-shift modulation techniques with synchronized data rates up to 1200 bits per second. Solid state components are used throughout the equipment. Error rates of less than 1 in 100,000 bits were recorded for line signal-to-noise ratios of 15 db or greater. Error-free data transmission was achieved in the absence of noise over a dynamic range of 50 db on the demodulation input.
