Ignition interference in CB
Guitarguy it sounds like the wires are up to par and since you don't have an electric fuel pump to cause noise there's not much you can do. The main problem lies within the cheap Radio Shack CB. They claim to have a built in noise limiter (called ANL) but it's really a joke and does little to stop noise. You need a radio with an IF noise blanker (NB). How soon do you need this for your trip and do you have any extra funds to buy a better radio? I was cleaning out the basement last week and ran accross a couple old CB's I was planning lo listing after I test them. One is a Tram and the other is a Courier. Don't remember if the Courier has NB or not but I know the Tram does as it was the top dog when it was made. Wasn't planning on asking much for either.
BTW: I might even trade for Mopar parts if you have something I need. Let me know if that interests you.
