Refmo,
Yep, you pretty well covered it. I've checked 10 and 15m often, and never really saw anything, so I just moved along. Nice to see you caught a good scan on 10m! I'll bet you heard SSTV on 14227 only because the SSTVer's were probably trying to avoid QRM from the voice ops not paying attention to the "gentleman's agreement".
Jim... I've never seen anything on 40/80/160 so I just gave up. That doesn't mean that occasionally you won't. For me, I don't wish to exert maximum effort for minimal results, so I look elsewhere.
