I drive a truck, and have a Cobra 148 GTL as my primary radio. The
radio has had some work done to it, and since I got it back, I have
noticed the radio is much louder. It's like it's picking up background
noise. With the truck off, the radio is more quiet, and I can hear
much less static. With the truck on, it's giving me some awful static
and feedback from time to time when I pull next to another driver.
Also, if I turn my heat/air on, or turn my wipers on, the static gets
even louder. The radio may have had some mods done to it that would
boost the output, but I am definatly not running anything like a
linear amp. My question, is if anyone makes some type of filter that
will kill all this background noise. Any information would be greatly
appreciated.

Thanks,

Sounds like somebody did a chop job on your rig. Some of that noise can be
dealt with by installing a noise suppressor on the power cord as close as
you can get it to the radio. That should kill the engine and fan noise and
you can get one at any radio shack or walmart for about $10.00 But the best
solution would be to find a COMPETENT service tech to repair the problem at
its source.

I wonder if the noise limiter switch was used for extra channels.
