The Marconi Self-tuning System (MST)

Page history last edited by David Samways 5 years, 5 months ago Saved with comment





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.
