TABLE G -- ALIGNMENT CHART part 2

Follow alignment in order from left to right. Start with 3rd I-F adjusment in first column, then 2nd I-F, etc. Connect signal generator to ground post of receiver using a short heavy lead. Allow receiver and signal generator to heat up for several minutes.

Adjust 21kc. osc. Padder to max. out-put. repeat No.1 Band adjustment & 215 kc. osc. Padder adjusments 2 or 3 times to insure correct tracking and dial calibration. Adjust No.2 Trimmer on Osc. Unit to max. out-put. then adjust Trimmers on Det. R.F. and Antenna Units, in that order to maximum out-put, and decrease signal as required to maintain 10 milliwatts output. Repeat above Adjust No.3 Trimmer on Osc. Unit to max. out-put. then adjust Trimmers on Det. R.F. and Antenna Units, in that order to maximum out-put, and decrease signal as required to maintain 10 milliwatts output. Repeat above Adjust No.4 Trimmer on Osc.

Unit to max. out-put. then adjust Trimmers on Det. R.F. and Antenna Units, in that order to maximum out-put, and decrease signal as required to maintain 10 milliwatts output. Repeat above
NOTE A -- SENSITIVITY

Adjust signal generator until receiver output is 10 milliwatts. Turn off modulation of signal generator. Turn down receiver volume control until 0.3 milliwatts of noise output is reached. Turn on generator modulation again, and raise generator output to obtain 10 milliwatts on output meter.

NOTE B

This adjusment uses the noise developed in the receiver as only signal
