I have a couple of contesters within a few miles of me who were obliterating many kHz of the 160 band in this week's  CQ CW contest.  One has a Yaesu 1000D with 5+ kHz of phase noise, the other has a 1000MP with discrete spurs over at least 10 kHz.  Of course they both run big amps.  Another guy 50 miles away looked like he was sending MCW.  If the photo of his shack on QRZ is to be believed, he's running an Omni6 + amp.

Not necessarily an overdriven amp. Yaesu made several models of radios that did that, no matter what you did to them. I don't know if current models have the same problem, but you'll hear (and see on a P3) many of them ragchewing on any phone band. The P3 will show the splatter as widening of the waterfall on voice peaks.
