摘要:
The paper describes the television radio-relay link designed to convey the television-programme signal between London and Birmingham. It was installed initially to transmit this signal on a reversible one-way basis (the Part I system) in time for the opening of the Sutton Coldfield television transmitter in December, 1949. This facility is being followed by a modification to the system so that signals can be transmitted in both directions simultaneously (the Part II system). The design has been strongly influenced by the requirement that all terminal and repeater stations should work unattended. This feature demanded the provision of an elaborate supervisory and monitoring system and the installation of a complete range of standby equipment in all the signal and power circuits of the stations.
