I didn't realize that it's downlink was only 250mw.  No wonder.

I don't think AO-51 had a constant carrier.  But it seemed that way 
sometimes.  And, it frequently got my receiver to full quieting, 
while SO-50 almost never does that.

One reason why I was asking is that I have been working up to getting 
back on the FM birds via a handheld.  I have a place in the mountains 
in DN60, and I suspect that's much more rare than my home QTH grid 
(DM 79).  I was thinking of operating handheld from there, and activating it.

Thanks for your answer.  I really appreciate it.
