Installed Yaesu FT-100D Ham Radio Transceiver into my Expedition and immediately found the Ignition Noise was awful. Noise is most noticeable at rest. My installation consist of rear hatch antenna mount, is grounded to body. Stand alone Deep Cycle Battery located in rear compartment.
I have contacted my local Ford Dealer in Orange, Ca. and have an appointment setup for tomorrow. This does not sound promising as the service department claims to have no experience with this kind of problem. Any comments/suggestions would be greatly appreciated.

Update 2-2-2007 Ford Dealer could find no problems. Test consisted of hooking up to computer and running all test. No problems found.. Mechanic said it sounded like alternator whine. They advised against installing any ferrite cores due to computer problems that would probably occur.
