- Depends on how "smart" the charger is. If it cuts off the charging
- current to a tiny trickle after charging, its ok. If not, it will
- cook the battery. Caution: Some "smart" chargers are a bit stupid in
- that if you remove and then replace a fully charged battery, it will
- start a full charge cycle all over. This will NOT do the battery any
- good.

- Most home FM radios use the line cord as the antenna. By plugging in
- the charger, you increase the size of the "antenna". The portion of
- the electrical wireing inside the wall is (usually) inside shielding
- (bx, flex, or conduit).
