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, Rob - Grasshopper |

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. -- visit http://www.geocities.com/linearschematics/ |

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