The Method of Graphic Representation and its Application in the Theory and Practice of Radio Technology by O Herold
the library of the radio amateur. Even before the amateur radio movement, there were technical and sporting efforts that quickly penetrated into broad sections of the population: J.gen; all of them already surpass in scope and intensity the occupation with radio telephony. The Grlinde hierfiir are manifold. Other technical activities require not inconsiderable prerequisites. For example, if you want to build a small steam engine yourself - which was a favourite pastime of technically gifted Schiiler twenty years ago - you need a lot of tools and equipment on the one hand, but on the other hand you have to be a good mechanic in order to get a usable machine. The construction of spark inductors or electrifying machines, also a favorite activity in later decades, also requires many a manufacturing equipment and corresponding skill. Efficiency. Most of these difficulties are eliminated in the case of training with simple experiments of radio telephony. Even with some old objects present in every household, reception results can be achieved without any special skill. The construction of a crystal detector receiver is neither difficult nor expensive, and even with it one achieves a result that has the same effect on every layman who undertakes his first radiotelephone attempts: almost free from earthly distances, it is able to absorb energy from space in the form of signals, music, singing, etc. Hardly anyone who has started with simple aids in this way will be able to get rid of the occupation with radio telephony. He will try to use his knowledge and his Appara. He will try better and better circuits of higher quality in order to be able to use the radio amateur library more and more fully.| ISBN 13 | 9783642891007 |
