IF ALIGNMENT

Connect an output meter across the voice coil of the receiver.
Connect a signal generator to the standard Hazeltine loop model 1150 and compile it loosely to the receiver loop.
Set the signal generator to 455 KC and fully mesh the receiver tuning capacitor.
Keep the receiver volume at maximum and the output of the signal generator sufficient to give a readable deflection on the output meter. Adjust for maximum, I.F. trimmers c9, c8, c7, and c6.

Osc. Adjustment

Keeping the same setup as used for I.F. alignment, set the signal generator and receiver to 1600 KC and adjust oscillator trimmer C4 for maximum output.'
Next set the signal generator and receiver to 600 KC and adjust loop frequency padder C17 for maximum while rocking the main tuning capacitor,
Repeat the above procedure for R.F. - Osc. adjustment.
Next tune the signal generator and receiver to 1400 KC. and adjust antennae trimmer C2 for maximum output.
