Introduction (1965)
Present-day operators of HF communications systems are handicapped by the increasing cost of staff and of buildings, by a shortage of skilled technical personnel and by the overcrowded state of the HF band. The newly-developed MST (Marconi Self-Tuning) transmitting system has been designed to ease these problems as far as possible. It comprises a complete range of custom-designed equipment for a modern HF transmitting station, from line inputs to final radiation, which can be controlled entirely by one man.
For further information see here and for later (1968) details here.
