My lips are mutilated with all kinds of strange jargon, my mind is mutilated with still stranger ideas and is foot-sore and weary from travelling in new and rocky realms of thought. Ignition methods; shall it be make-and-break or jump-spark? Shall dry cells or storage batteries be used? A storage battery commends itself, but it requires a dynamo. How powerful a dynamo?
"It ain't in them batteries them batteries is all right!" piped a weazened little man who had been grinning wisely at the lack of mechanical ability so shamelessly exposed by his fellows. "Now in a jump-spark engine," he explained leisurely, with a knowing squint of his eyes and an uplifted explanatory forefinger: "in a jump-spark engine, gentlemen, there is a number of things to consider.
Because a jump-spark sets up periodic oscillations, that is, the oscillations are discontinuous, it cannot be used for wireless telephony. An electric arc or a vacuum tube sets up sustained oscillations, that is, oscillations which are continuous.
Amateurs generally use a jump-spark for sending wireless telegraph messages and the vacuum tube for sending wireless telephone messages. The Spark Gap Wireless Telegraph Transmitter.
He agreed with his son that it was a bargain and that it could easily be put in fine shape. The youth spent all the next day and part of the following working on the craft. He overhauled the ignition system, which was the jump-spark style, cleaned the magneto and adjusted the gasoline and compression taps so that they fitted better.
