Abstract :
There is described briefly a short-wave single-side-band system which has been developed for transoceanic radiotelephone service. The system involves the transmission of a reduced carrier or pilot frequency and is designed to include the testing of twin-channel operation wherein a second channel is obtained by utilizing the other side band. The paper indicates the reasons which led to the selection of this particular system and discusses at some length those matters which require agreement between the transmitting and receiving stations when single-side-band transmission is employed.
