frequencies, and yes, even INTERFERENCE, as long as it is non intentional, is
 part of the signed, contractual agreement between you and the federal

Don't believe it?... Read part 97... 

If I were feeling really cynical I would suggest that you stay away from my
contest, as you did to me.... But, I signed the same contract, so come on in,
the waters fine...

First of all, would really like to thank all of you who have responded 
with hints. Will summarize when finished.

To recap, vehicle is a new 95 Ford Ranger with 2.3 engine. Antenna is
mounted right off center of a burnished aluminum across the bed tool
box. Rig is TS-50 fed right off the battery. Hustler antenna.

Problem: Extreme EMI S8-9 

Accomplished so far. (1) had interference filter installed by dealer at
fuel pump in tank. Result, -2-3 S units. (comment: that fuel pump gets
its DC from bus with neg and positive terminals which are merely push
on clips. Nearly scared me to death. If that sucker ever takes a hit
which would knock one of the clips off, I pray I am out of gas at the 
time. (2) have grounded the tool box everywhere. (3) installing grounds
from engine to frame.(note: you would not believe some of Ford's 
grounds. pressure clips with good braid pushed over PAINTED surfaces.

NEW questions, and please comment on any of previous. While I was at 
the Ford dealer, I showed them a few hot spots ( using the old trusty
hand held transistor radio. Alternator was one of worst offenders.
(grounded that sucker today to main frame. Dealer mentioned that the
Mustang has a shielded alternator. Now main question; Would it do any
harm to substitute components made for a different vehicle. (assuming
they would mount properly) And does anyone know of a commercial group
who specialize in "quieting"? The ignition system is pretty well out
of the question, but, assuming it had common mounts and wiring, could
you substitute a "quiet" alternator? One of the other major sources
is the air intake filter housing. ( it's got some little device in it )
Would it do any harm to wrap the cable assemblies with aluminum 
tinfoil, grounding them along the way. You wouln't believe Ford's 
ground system ( got a complete schematic of the electrical system. They
run a ground or grounds to a common point, where other grounds are 
hooked in, ect, until finally the ground the wire. Picture a Christmas
tree with no needles and you have a good idea.

Sorry this so long, but thanks for reading.

73, Ed, K4SB
