Abstract
230,901. Roddis, C. H. Dec . 17, 1923. Receiving sets, construction of; coupling aerial and detector circuits; receiving systems and apparatus.-A receiving circuit comprises an aerial tuning coil or variometer and a second tuning coil or variometer arranged in a shunt circuit between aerial and earth which also includes a crystal detector. Fig. 3 shows the preferred circuit comprising a crystal detector 15 an inductance 10 having tappings 24, 26 and a coil 40 sliding within the inductance 10. The earth and aerial are normally connected at terminals 29, 30 while for long wave lengths the aerial is connected to terminals 32 and the earth at terminal 29 or 30.
