S-9 noise when we put the radio in it. My F150 with a V6 gas engine has no noise, but it was S-9 noise when just parked next to the diesel.

Just as a further aside to this, while driving back down today I noticed that some buses seem to produce a lot of noise. In particular, the Citylink service buses which use Volvo B10M chassis and VanHool bodies produced a little burst of S9 noise as I went past. Other similar buses didn't even make the S-meter flicker, let alone open the squelch.
