C.  PLL  Input  Level Adjustment

1)  Set  the  mode  selector  to  AM,  and  the  clarifier 

Control  to  center,  and  set  the  band  selector  to 

Position  C of  CH  19.

2)  Connect  synchroscope  to  TP-4  (pin  terminal 

between the C-82 anu  R-107).

3)  Adjust  L-16 for maximum  RF  output.

D.  [VC 0]  Adjustment

1)  Set  the  mode  selector  to  AM,  and  the  clarifier 

control  to  center,  and  set  the  band  selector  to 
position  E with  CH 40.

2)  Connect synchroscope to TP-3.

3}  Adjust  L-18 for maximum  RF output.
4}  Connect  DC  Voltmeter  to  TP-2  .(pin  termin 

between the R-109 and  R-258 from  IC-5).

5)  Adjust  L-17 to  DC 5.0+  0.1 V.
6)  Check  A band  of CH7, must be DC 1.5V minimur

E.  [Off -set  Frequency]  Adjustment 

>■

1)  Connect  frequency  counter  to  TP-3  (pin  termin 

of L-18).

2)  Set  the  Mode  Selector  to  AM,  and  the  Clarifi 

Control  to center.

3)  Set  the  Band  Selector  to  position  C  of  CH1
4)  Adjust  L-19 for  16,040  MHz  ±50  Hz.

5)  Set the mode Selector to  USB.

6)  Adjust  L-20 for  16.0425  MHz±50  Hz.
7)  Set the mode Selector to  LSB.

8)  Adjust  L-21  for  16.0375  MHz±50  Hz.

9)  Set  the  mode  Selector  to  LSB.  and  transmit 

station.

10)  Adjust VR-15 for  16.0375  MHz ±50  Hz.
