Receiver Alignment

Test Equipment
1.    RE Signal Generator
2.    V.T.V.M.
3.    8 ohm dummy load (10 watts)
4.    Distortion Meter
5.    Power Supply
6.    Oscilloscope

Alignment Procedure
1.    Connect Pin 4 of Mic jack to ground.
2.    Connect RF signal generator output terminal to antenna jack, set modulation 1KHz at 30%.
3.    Connect power cord to power supply.
4.    Connect dummy load to EXT speaker jack.
5.    Connect V.T.V.M., oscilloscope and distortion meter to dummy load.
6.    Set signal generator and radio to Ch19.
7.    Turn squelch frilly counterclockwise and the volume fully clockwise.
8.    Signal input must be kept as low as possible, to avoid overloading and clipping.
9.    Adjust T101, T102, T213, T103, T104, & T105 for max. on V.T.V.M..
10.   Reduce output from signal generator so that audio output remains about 500mV-2V.
11.   Repeat steps 9 & 10 to obtain max. output.
12.   Set output of signal generator to 1uV.
13.   Check that V.T.V.M. indication is above 4V and S+N/N is below 10dB.
14.   Check that audio output is over 4V on channels.
15.   Turn squelch volume fully clockwise, and adjust RV3 so that audio output appears.
16.   Adjust VR1 so that meter indicator is set at S-9 position.
