nd gives increased strength of signals from a given sta-tion. Part of the energy of the oscillations of radio-frequency flowing in thetelephone circuit is repeated back to the secondary circuit through the couplingcoils (of radio-frequency) L-1 and L-2, and the amplitude of the grid oscillations•… … ^^y^ Fig, 182—Audio-Frequency Repeater Circuit.

The complete process does not interfere with the action of the valve as a detector,which at the same time charges the grid condenser in the usual fashion, but with in-creased strength, due to the…
