Every time I pass a semi on the highway, I can hear junk coming from the engine computer, or something, on VHF. It does have a carrier and isn't just injectors. That's an additional noise. It doesn't matter what repeater freq I'm monitoring, squelch is open from just about the cab door until I'm clear of his bumper. Pretty trashy. I don't know how some of these truckers run VHF gears in them.
