Confirmation Step 3: Antenna System Simple Inspection [Radio]

~1min read
  • Because the antenna system is equipped with a capacitor, the continuity cannot be checked. Therefore proceed the following simple inspection.

    • Turn the AM radio on.

    • Tune to the frequency that there is no broadcast and you will hear a buzzing sound.

    • Turn a work light on and shake it around the antenna rod. (around 10—20 mm {0.40—0.78 in})

      CAUTION:
      • Use a fluorescent light type for the inspection. Accurate diagnostic cannot be done with a different type of light.

    • If a whirring sound from the speaker synchronized to the work light movement is confirmed, the antenna system is normal.
