I looked at Sailmail, looks complicated, and what sort of range do you
get? Major down-side for both Winlink and Sailmail for me a Windows.

Like all HF radio it depends on the sun spot cycle, conditions in the
ionosphere and time of day. Typically 1,000 to 2,000 miles is quite
doable with a little patience, sometimes a great deal more.

AFAIK the Winlink and Sailmail clients are Windows only, not that bad
in my experience. I use Win2K on all my boat laptops and they never
crash.
