Robert, I have used my K3 mobile a few times. Be sure you have a good, heavy power lead that goes directly to the battery with the proper fuse near the battery. If you are going to run mobile for the long term, maybe install some Jack Nuts (like Molly bolts in drywall, but for metal) and fabricate a bracket. See if there is a tech bulletin from your car's maker on mobile radio installations. They might have some warnings on where to run antenna cable. Be sure you use a high quality double shielded antenna cable. I oversee radio installations in patrol cars, and keeping he RF where you want it is important. I can't tell you how the K3 noise blanker works on ignition noise...My car is Diesel.
