EDITORIAL

It is high time the authorities took a more realistic view of the relationship between radio and foreign spies. Twenty years ago it was reasonable enough to expect to find that every enemy spy, in books of course, had a radio transmitter with which to pass on the secret codes. But in these enlightened days it is quite ridiculous to find that a special form has to be filled in before a type 807 valve can be purchased, apparently to prevent it being put to nefarious uses by enemy agents! Any person with the remotest knowledge of radio transmitting should be able to appreciate that any old 6L6 will do exactly the same job as the 807 for the brief space of time which a spy would need to send his messages. The 807 would have a life of so many thousand hours, whilst the 6L6 would be so overloaded that its life might be curtailed to a few hundred hours, but would that worry the spy? Any spy worthy of the name could make up a most effective transmitter from receiver parts, so why the fancy forms for the poor 807, for condensers of high voltage rating and so on? Then again in the matter of penalties. If an over-enthusiastic lad can't wait to turn 18 in order to get his ham licence and goes on the air as a pirate, he commits a crime far worse than burglary or arson. Apparently it is still another echo of the bad old days when spies used radio transmitters! How many decades will it be before Those-in-Charge recognise radio transmitting as a reasonable hobby for intelligent people? A. G. HULL.
