Confirmation Step 3: Antenna System Simple Inspection - Radio

CONFIRMATION STEP 3: ANTENNA SYSTEM SIMPLE INSPECTION [RADIO]

- 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})
NOTE:
- 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.
