ALIGNMENT PROCEDURE

Connect output motor across voice coil.

Connect the signal generation to the standard Hazeltine Loop model 1150 and couple it loosely to the receiver loop. Set the volume control at maximum, and fully mesh the tuning capacitor.

The output of the signal generator should be just sufficient to give a readable deflection on the output meter.

Set the signal generator to 453 kc and adjust i-f trimmers for maximum output in the following order: C10, C9, C8, C7, Repeat sequence if trimmer's were badly maladjusted.

Set the signal generator and receiver to 1600 kc and adjust the oscillator trimmer C2 for maximum output.

Set the signal generator and receiver to 1400 kc and adjust the antenna trimmer 04 for maximum output.

Set the signal generator and receiver to 1600 kc and readjust oscillator trimmer C2 for maximum output,

ALL VOLTAGE AND RESISTANCE MEASUREMENTS MADE WITH RESPECT TO CHASSIS GROUND AND WITH A LINE VOLTAGE OF 116 V.A.C.
