Edwin H Armstrong, pioneer of frequency modulation and among the earliest workers in regeneration, super-regeneration and the super-heterodyne

We had the sad duty of recording the death, by his own hand, of Edwin Armstrong, one of America's most distinguished radio pioneers. His most important work had been in the fields of valve regeneration, the super-heterodyne receiver, super-re-generation and frequency modulation. He had been involved in much patent litigation. Only a few weeks before his death Armstrong had written a letter for our correspondence columns to keep the history straight on the early development of the triode. Nobody, he contended, had made a serious study of how it worked until six years after it had been introduced.

Parliament passed an Act setting up the Independent Television Authority. As a result, there was a minor revolution in the design of television receivers, which in future would have to work on Bands I and III.

No, Sir! This is the set and that is the converter. (misgivings were being expressed about the technical difficulties of adapting existing television receivers for reception of the projected Band III service.)

In brief: Printed circuit techniques now widely used; ferrite rod aerials in portable receivers; permanent 'Eurovision' television links set up on the Continent; interest in high-quality sound reproduction reached new heights.
