I've run into a problem that I need help with, and your readers may also need to know about this problem. My customer has a '93 Chevy six-cylinder pickup truck that is causing interference to the two-way radio receiver on 158.385MHz. It appears that the vehicle's computer is producing a signal every 1MHz from about 40MHz to 200MHz and was found with a spectrum analyzer. The Chevy dealership replaced the computer, and the problem is still there. Another '93 truck was tested and found to have these same signals but at even multiples: 157.000, 158.000, 159.000, etc. An '87 truck was tested, and its signal was at 158.375, 159.375, etc. So far, I'm having a problem getting through to General Motors or Delco for some help. Maybe one of your readers has already run into this and has some help for me? How about running this through your magazine?
