2、nch diameter loop of bell wire across its output terminals and then locating the loop about one foot from the radio loop antenna. To prevent possible errors in com parative peak readings, the position of signal generator loop with respect to the radio loop antenna should not be changed during measur

3、ement. The output meter is connected across the terminals of the loudspeaker voice coil. The receiver volume control should be turned to maximum and test oscillator signal output attenuated during alignment to develop not more than 1)4 volts output meter reading at the loudspeaker. mo m3 a J ; ! ! 11 riFsrvrt1 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 RadioFans.CN
