Tri-Tet Transmitter

New Zealander’s Successful " Design JrEATURED in .the November issue of the ""T. and R.. Builetin,’’ the official organ of the Radio Society of Great Britain and the British Empire Radio Union, is a six-page article on "A Tri-Tet Linkcoupled Push-pull Transmitter," from the pen of the designer, Mr. G. McLean Wilford. The editor of the Bulletin states: ‘‘The tri-tet circuit forms the basis of this very modern transmitter, and by a novel arrangement either crystal or master oscil--lator control may be used. It is thereby possible to operate on a fixed crystal frequency in four amateur bands, or on any predetermined frequency in five bands. Link coupling between stages and a push-pull final amplifier contribute towards making this one of the most efficient transmitters yet described in this journal. This equipment was anoutstanding exhibit on the society’s stand at Olympia last August."’ Mr. Wilford is a son of Sir Thomas Wilford, ex-High Commissioner for New Zealand. He is an old boy of Wellington College, and is an engineer attached to the staff of the Central Electric Board, Birmingham (England).
