Radio Noise | |
---|---|
Radio noise and other annoying buzzes are many times transmitted through an AM radio. Here is a check-off list of the most likely causes: |
The best way to eliminate radio noise and interference is at its source. Here is a check-off list of possible solutions: |
Dimmer switch | The most obvious solution is to turn off the offending device. |
Neighbors dimmer switch | Temporarily switch the radio from AC power to battery power to see if the interference is coming from the electrical outlet. If the noise stops, our Radio Noise Filter/Surge Protector will dramatically reduce the interference. |
Fluorescent light | Turn off all circuit breakers to see if the noise stops. If it does then you know it is something in your house. Turn off one circuit at a time to isolate what area the noise is coming from. |
Computer | Use a battery operated radio as a direction finder. Turn the radio until the loudest noise is heard. The front and back of the radio will usually point to the noise origin. |
Touch lamp (even when turned off) | Carry a radio around the neighborhood. Ask other neighbors if they have problems (with radio noise) |
Automatic on/off night lights | If a power pole is suspected, call the utility company and they will usually check the area and wash the insulators |
Automatic outdoor yard lights | Often grounding a radio will reduce hum caused from AC line noise. Unfortunately most receivers do not have a ground connection. |
Electronic bug and pest controllers | |
Light bulb that is about to burn out | |
Faulty electrical switch | |
Nearby television set | |
Neighbor using fluorescent lights | |
Christmas tree lights & other blinking bulbs | |
Neighbors dimmer switch (apt. complex) | |
Scanners | |
Cell phone chargers | |
Dirty insulators on nearby power pole | |
Electric blanket | |
120V AC smoke detectors (battery operated OK) | |
Ionic Breeze or other electrostatic air purifier | |
Ultrasonic motion detectors | |
Appliances with motors | |
