The Manchester¿Kirk O´Shotts television radio-relay system

The first permanent broad-band super-frequency system to be operated in Great Britain was put into public service in March, 1952, to relay television programmes between Manchester and Kirk o´Shotts and so extend the B.B.C. television service to Scotland. The paper discusses the considerations which led to the adoption of a 4 000-Mc/s radio-relay system for this service, and gives a detailed description of the design and performance of the equipment. The conclusions which have been drawn from some fifteen months of daily operation are given.
