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:

  Dimmer switch
  Neighbors dimmer switch
  Fluorescent light
  Computer
  Touch lamp (even when turned off)
  Automatic on/off night lights.
  Automatic outdoor yard lights
  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

Note: Sometimes pool chlorine generates electrolytic action which causes radio noise over a wide spectrum of over 500' from the device. Unfortunately there is no known cure.

The best way to eliminate radio noise and interference is at its source. Here is a check-off list of possible solutions:

The most obvious solution is to turn off the offending device.
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.
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.
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.
Carry a radio around the neighborhood. Ask other neighbors if they have problems (with radio noise).
If a power pole is suspected, call the utility company and they will usually check the area and wash the insulators.
Often grounding a radio will reduce hum caused from AC line noise. Unfortunately most receivers do not have a ground connection.

  • This WiFi Antenna is hands down the best. It allows me to connect to a business almost a half mile away. Two months time and this baby paid for itself. I am a very happy with my purchase.
    — John A., Mill Valley, CA
  • This radio deserves five stars because it sounds great, the ease of use and preset stations. This radio will become your favorite radio, also backed by great customer service if ever needed, thank you very much.
    — Pete P., Santa Rosa, CA
  • This is an excellent internet radio. I have had the unit playing constantly from the time I received it. Excellent sound for such a small unit and the remote works wonderfully.
    — James H., Richmond, BC
  • Good sound, lightweight and comfortable; not too tight on the head. I like one feature; it doesn't tell you where to place the speakers, left side or right side.
    — Harry W., Manassas, VA
  • I purchase this product specifically for AM recordings and it has worked superbly. I wanted to wait awhile before I gave my opinion on the product. It has worded exactly as advertised and more.
    — Jack L., San Pedro, CA
  • Very nice, economical home lighting. If you're used to the white light of fluorescent bulb replacements, these will offer the same type with no toxic ingredients or damaging UV radiation.
    — Gary B., San Francisco, CA
  • This antenna does work well; however placement and the shape you have it bent into is very important. I live about 70 miles away from Toronto and receive a lot of Toronto FM stations static free with the FM reflect.
    — Thomas S., Buffalo, NY
  • I'm not sure how I gone this far in life without it. I just love it. The best sound ever from an AM radio.
    — James G., Springfield, MA
  • This device is awesome. As a contractor, I can not access my customer's network for security reasons. Now, with my office on the second floor, I can connect to a WiFi hotspot 1.5 miles away and my signal strength is strong!
    — Robert S., Tabernacle, NJ
