Re: Common Interference Sources

Chris Rogers

Most plug packs and chargers are of the Chinese switch mode variety which are a big source of RFI. The best way to isolate noise is to tune to the noise on your radio turn all your appliances (everything) off in the house and turn the power off at the meter box. If the interference is gone, turn the power back on and gradually turn appliances back on one at a time until you find the source. There could be multiple sources in the house. If the interference is still there when all the power is off in the house it must be coming in externally to the house, a neighbour or a power line etc. The majority of times it will be something in your house.
