How can I locate sources of AM/FM interference on my vessel ?

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