Not related to AM, but my P3/SVGA sees a LOT of very splattery SSB 
signals generated by low cost JA transceivers. A few weeks ago during a 
contest, I saw it on the signal of a local, fairly new ham, told him 
about it, and volunteered to help him fix it by listening and watching 
as he adjusted drive to his amp. Turned out it was his radio, a $1700 
Yaesu FTDX3000. Splatter from these signals is often as wide on both 
sides of the signal as the signal itself. I measured his splatter as 
less than 20 dB down from his intentional signal.

There's a roundtable that hangs out just above the FT8 slot on 160; most 
of the radios are clean, but there's usually one or two that splatters 
down into FT8.
