Apparently the audience of the Baird 30-line broadcasts was greater than we had thought; publication of a proposal to suspend the transmissions brought, within the week, protests from a large number of readers. No doubt the transmissions on this system, crude as it was, did a great deal to stimulate work on television; some correspondents were now using cathode-ray receivers.

The introduction of suitable valves now made practicable the 'universal' ac/dc receiver, Without a transformer.

Our contributor 'Cathode Ray' started his inimitable series of expository articles in 1934. Apart from his services as a talented and sympathetic expositor of the trickier aspects technology he has been a doughty fighter against the many irrational and confusing technical terms which make life so difficult for the student and beginner. And 'Cathode Ray' has won many of his battles: few of us now dare to speak of 'non-linear distortion' unless we really mean it is the distortion which is non-linear!
