I drive a 1988 dodge dakota which has an electronic control module to
control timing and fuel delivery.I've installed a 10/12m ranger 2970
radio in it.I've also modified the radio somewhat by installing a
modulation/speech processor/compressor.My modulation is presently at
95%.When I key the mic. the ECM becomes flooded with RF and disturbs
the control to the fuel delivery and timing to the point of stalling
the the truck.I've tried to RF harden the ECM by wrapping it in tin
foil.I'e also added a DC ground that runs from the radio to ground and
to the antenna then back to the truck ground.Still the problem
exists.Any suggestions short of removing the speech/mod compressor
will be greatly appreciated. 73s...K2NBO....
