The performance of a radio-telegraphic transmitter, with special reference to the new installation at north foreland

The paper deals with the performance of a commercial type of l¿-kW spark transmitter. The electrical quantities in the various circuits are discussed, and experimental results are given which enable a complete analysis of the losses to be arrived at. Particulars of the performance of this type of installation under traffic conditions show that the type of signal emitted gives high commercial efficiency.
