Absolutely! I know that Winlink has stopped supporting PACTOR I and I
suspect
that Sailmail has too or will soon. PACTOR I is 100 bits per second.
PACTOR-II
is 200 bits per second. PACTOR III can go much higher and is adaptive. I
generally
connectd at around 3400 BPS but it can go a bit higher with a really good
signal.

on many TNCs but PACTOR II and III are only available via the SCS TNCs.

Is it worth having equip that uses Pactor 2 and 3?
