PLL UNIT
 
(1) PLL Reference Oscillator Adjustment
 
Set the MR switch to off, and connect a frequency counter to pin 9 of Q2041. Adjust TC2002 for a reading of exactly 3.2 MHz on the counter.
 
(2) PLL Local Alignment
 
a. Connect the RF probe of a VTVM to pin 1 of J2005. Adjust T2005 and T2006 for a maximum meter reading on the VTVM (typical value: 100-200 mV RMS).
 
b. Connect a frequency counter to pin 1 of J2005. Adjust TC2001 for a reading of exactly 47.6 MHz on the counter.
 
(3) VCV Line Adjustment
 
a. Connect the DC probe of a VTVM to TP2005 (PLL Unit), and rotate the main dial to the "1000" position on the analog dial. Adjust T2007 to secure a reading of 7 volts on the VTVM.
 
b. Rotate the main dial to the "0" position on the analog dial. Make certain that the voltage is within the range of 1 .5 - 2.0 volts.
 
c. Connect the VTVM DC probe to TP2003, and rotate the main dial to the "1000" position. Set the BAND switch to the 5 MHz. band. and adjust T2004 to secure a reading of 7.4 volts on the VTVM.
 
d. Change the BAND switch to the 12, 20. and 29 MHz band positions, and adjust VCO coil, T2003, T2002, T2001, respectively, to secure readings of 7.4 volts on the VTVM.
 
e. Set the BAND switch to the 21, 13 and 0 MHz band positions, and rotate the main dial to the "0" position on the analog dial. Make certain that the voltages at TP2003 are within the range of 1.5 - 2.0 volts.
 
MEMORY UNIT
 
(1) M FINE Adjustment
 
Set the M FINE control to the 12 o'clock position, and connect a frequency counter to pin 9 of Q6021. Adjust T6003 for a reading of 8.192 MHz on the counter.
 
(2) VCV Line Adjustment
 
Initially set the MR switch in the OFF position, and connect a VTVM to TP6001. Rotate the main dial to the "0" position on the analog skirt, and push the M button. Then press the MR button. and adjust TP6001 to secure a reading of 6.6 volts on the VTVM.
