I did most of the grounding mentioned here on our Chevrolet's and Ford
stationwagons in the 70s, and 80s. I have no noise problems with my Impala or
Astrovan. The noise blanker and DSP on the 706 <ICOM> will take care of it. I
have the 706MKIIG and it probably has the worst receiver ever made hands down!
But, it seems to work better in the car than at home.

engine hood on both sides. We even went as far as a shielded ignition. Also,
coaxial by-pass capacitors on the 12 volt generator. (this is a few years back)
The alternator can be troublesome as well. Installed grounding devices that
went in the axel hub caps and injected a powder that prevented static build up
in the tires. Ohoo yeah,,,ground straps between the chassis and frame (each
side). All this to get the noise floor down for operation on the 40mHz FM
band. I would expect the vehicles of today are noiser with all the computers
on board.
Gud Luck.

Ford has stopped doing this as a TSP? It worked great on my 2002 F-150 (for
the fuel pump noise, anyway). Took the overall noise from S9+20 down to
S9. Grounding the tailpipe took the noise down to S6. A few things I've
tried after that haven't helped much. Mostly ignition noise left now.

The Ford fuel pump RFI filter produces mixed results and requires
dropping the tank because the filter is installed right at the pump. A
better way (IMHO) is to cut into the pump wiring at the nearest
connector (about 2 feet from the tank) and installing coaxial type
feedthrough capacitors. You can find more info at
http//www.4x4central.com in the ham radio forum.
