Interference caused by a car Often, car radio interference originates in the ignition system or the charging circuit. However, it can be linked to any electrical accessory in the car so you may need to undertake a number of checks to find the source. However, the first check is to ensure the radio is properly earthed.

There are two ways to suppress interference from motors. First, try fitting an earth-bonding strap between the motor casing and the bodywork. Use a length of copper braiding, or a piece of heavy-gauge wire. Suppressor and power-supply choke fitted to an electric clock.

A simple method of determining the location of electrical interference is by using a portable battery-powered AM radio tuned to a quiet frequency at the lower end of the dial. You should hear static or a buzzing sound as you get close to the source of the interference.

There are two basic strategies to control RFI. The first prevents it from coupling in the first place by using filters or arc snubbers at the source, relocating equipment or rerouting cables, using signal path ground isolators or adding shielding or ferrite chokes to cables.

This interference may be caused by equipment in your home, such as hair dryers, sewing machines, electric drills, doorbell transformers, light switches, smartphone chargers, power supplies, computing devices, washing machines, clothes dryers, fluorescent lights, LED lights, or garage door openers.

A tracking transmitter broadcasts a radio signal which can be detected by a directional antenna (typically a Radio Direction Finder.) By rotating the antenna one can determine the direction the signal lies in and of course whatever it may be attached to. The EPIRB is an example of a similar device.
