[Kenwood] (no subject)

Help.
Anyone running a Kenwood TS50 in a 2002 GMC V8 Pickup?  This truck also has
the rear wheel steering.
A friend of mine is having Computer type sounding noise from the vechicle.
Disconnecting the antenna gets rid of the noise.
Using a portable Short-wave receiver the noise can be heard up to about 12
feet.
A MFJ DSP unit does not touch the noise and of course neither does the Noise
Blank have any effect on the crap.
The same rig, antenna and DSP unit was run in a 2 year older Blazer with no
problems.
With the rig on and turning the igniton key to ON position their is no noise
either from the initial fuel pump start-up or the computer and any other
noise producing beasts in the truck.
Any ideas, or who we may contact at GM? The dealer is of no help.
Thanks Jim/w8ngo
