Kenwood TS-820 (TS 820 TS820) General Alignment Procedure

The purpose of this bulletin is to give a simplified alignment procedure for the TS-820 and TS-820S transceivers. We have tried to combine some of the step and rearranged the sequence of step so the alignment may be done quicker. This may be used in lieu of the alignment procedure in the Service Manual.

  1. Adjustment, A.V.R. unit (X49-1080-00)

    1. Adjust VR1 for 3.3V
    2. Adjust VR4 for 9V.


  2. Adjustment, V.C.O unit (X50-1330-00)

    1. PLace ST to TONE and connect a frequency counter tp TP5.
    2. Adjust T1-T11 for proper frequency. (See table)

      Note: I'm not sure about the data in the table are correct, because the drawing i read from was very bad.
