About a year ago, at the NCTA Convention in Denver, the project now referred to by the somewhat cryptic name of AML--meaning Amplitude Modulated Link, but more descriptively called " Short Range Multi Channel Microwave"-- had already been in active study and/or experimentation for six months.
Today, the result of this conceptual, theoretical, engineering, laboratory design and construction work is a physically operating system. This system is transmitting up to 12 color grade, standard television channels, modulated on a single carrier, over a six-mile path in New York City, under an Experimental License issued by the FCC.
