Ford had a lot of ways to dampen RF noise that is generated by ignition, generator, sending units, etc. Most were handled by addition of capacitors added on to all the sources. They had kits for this. RF is also generated by outside sources from other motor vehicles, lighting with ballasts, and other transmission sources.

Depending on type of equipment used for alterations and type of antenna, there may be more sensitivity to this type of noise. Some radio sets can be adjusted somewhat to dampen sensitivity.
