How Can I Locate Sources of AM/FM Interference on my Vessel?

A simple way to try to locate on-board sources of interference is to use a portable AM/FM radio and point the aerial at different areas or electronic devices while in AM mode. You will hear the interference as you pass the source of interference. You can also eliminate interference sources by turning electronic devices off to test if there is a marked improvement, then work your way through your electronic devices to determine what, if any, are contributing to the issue.
