2、E DETECTOR, and two stages of AUDIO FREQUENCY AMPLIFICATION over a wavelength range of from 200 to 5000 meters. It is designed for use on a loop antenna with a parallel variable air condenser for tuning purposes. This method of radio receiving combines the advantages of directivity with a minimum of

3、 interference from static, and local electrical disturbances. The use of a loop eliminates the necessity of erecting an outdoor antenna. Set the wavelength switch knob in the lower left corner to the proper position, pulling it out to receive wavelengths between 200 and 500 meters, and pushing it in
