Troubleshooting Radio Frequency Interference

So when you’re list of on board electronics and gadgets looks like a summary of this website, how do you make sure interference won’t be spoiling the party? Well, start by reading John Payne’s electronics column in DIY boat owner magazine’s 2004#1 issue.
“Noise sources on a boat are often classified as radio frequency interference (RFI) or electromagnetic interference (EMI). They are major enemies of electronic systems, corrupting your GPS position fixes, degrading radio communications and causing general electronics performance problems. RFI is essentially interference and noise that is superimposed as a disturbance or voltage transient either on the electrical power supply or the data and signal lines. This is then processed along with the good data to corrupt or degrade the processed information.”
