2. Manipulative
3. Simulative |
|
|

Definition
|
|
Term
| Briefly explain what you can do to find out if radio interference is due to a faulty radio set or coming from an outside source? |
|
Definition
| Disconnect the antenna. If the interference stops, it is not due to your radio source and comes from an outside source. If it doesn't stop your radio set needs attention. |
