In congested districts it isparticularly undesirable to receive radio telephone signals RECEIVING EQUIPMENT 83 with the tube oscillating even though the beat note has beeneliminated by tuning so that its pitch becomes lower andlower until it finally disappears, as the oscillating tube sendsout weak radio waves from the receiving antenna, whichwill cause considerable interference with nearby stationstuned to approximately the same wave lengths. The platecoupling coil Ls is frequently called a tickler coil. Tuned Plate Receiver.—The coupling between plate andgrid in the preceding circuits is principally of the typeillustrated in Fig, ll and known as magnetic type of receiver which has attained very wide-spre
