Hmm, really?  Tell that to the JA I worked while mobile in Sydney, or the VK6s
and ZLs who I spoke to for most of last year on 10FM. :-)  Not to mention the
Asian pirates that are an everyday occurance on this side of the world. :(

 FS> 1. It isn't that much of a problem.

Can't speak for the US, but I'd agree on this side of the world.  A bigger
problem is pirates on the 2m uplinks.

Who wouldn't! :)  But I'd try and keep it brief, or if a ragchew was
developing, QSY to the SSB part of the band, if possible.

Good point.

Well, I quite like 10FM, I work it from time to time, either F2 paths in the
2000-3000km range or sporadic E to interstate repeaters.
