The flagstaff-phoenix tj radio system

The bell telephone laboratories, inc., have recently completed the development of a microwave radio system to operate in the 11-kmc (kilomegacycle) band. The system is coded TJ and is designed for short-haul and medium-haul systems. One of the first systems was installed between Flagstaff and Phoenix, Ariz. It is hoped that a description of the system may be of interest to other engineers in the communications industry.
