John,

I thought that was the WARC original ruling.  I've been on 30 since the band 
was opened to hams, even when you could not transmit on something like 109 
to 112 without being ticketed by the FCC and I bet I haven't heard ssb on 30 
more than 3 or 4 times.  All Spanish speaking, too.  I copied Spanish 
speaking rag chews outside all ham bands many times over the years.  I can't 
speak much Spanish other than enough to make the contact and sign out but I 
recognize ham related words in ham conversations on the bands so even those 
I heard out of band, I knew were indeed hams.  I had a missionary friend 
HI8XRM, Dominican Republic, and he told me he could operate ssb anywhere in 
the phone or cw bands.  That was before 30, 17, and 12 were bands of course. 
So maybe there's no restriction outside the U S.

Phil.
