The operation of such a set is considerablymore involved than the plain receiving equipment, but onthe other hand the self-amplifying feature greatly adds tothe results. Furthermore, it is necessary to use metallic 142 RADIO FOR EVERYBODY shields between the operator and the components of theregenerative set, since the capacity of the body of theoperator materially affects the delicate adjustments of theregenerative set. Most of the better regenerative instru-ments are provided with metallic shields inside the cabi-nets, so as to reduce the body capacity trouble to a mini-mum. In other instruments the dials are of metal andare grounded to act as shields. GL. Another method of obtaining a regenerative receiver.

There is virtually no end to the different arrangementswhich can be followed in receiving radio signals. Thewiring diagrams shown in the foregoing pages are onlyintended as a preliminary guide, and are offered as sug-gestions to the beginner. As one becomes more proficientand versed in the radio art, one soon learns other arrange-ments which may p
