Low-level-modulation vision transmitters, with special reference to the Kirk O´Shotts and Wenvoe stations

The first part of the paper deals with some of the general problems involved in the design of a television transmitter, and the reasoning which has led to the adoption of a low-level modulation system. The remainder describes some of the particular features of two high-power low-level-modulation vision transmitters installed at the B.B.C.´s Kirk O´Shotts and Wenvoe television transmitting stations.
