There is quite a lot involved in radio suppression on a veh. Lots of earth / bond straps every where. A suppressor on the generator and the distributor, some shielded wiring (generator to regulator) etc. and filter boxes. Have a look at Jeeps, and Dodges. The American manuals give pretty good info on this sort of thing, with lots of photos. Most American production rolled out of the factories with it all done from around 1941. The thing is that its not just the veh. with the radio in it, It's all of the vehicles in proximity that cause a problem.
