I sure that your experience is good and I too have been designing and operating
C3 units since 1989 and each use is quite different...mainly for the USAF, MARS,
NDMS and local ARES operations.

One of the popular considerations is that you use volunteer operators which is
true; however, in all the situations I encounter, we don't allow individuals
without training and actual operational experience operate these C3 units...so
what computer operating system, computer or radio hardware you have is not
important. In my current project, we have communicators who prior to
volunteering were not hams and as part of their training must become
licensed...most do not operate on the hams bands except from the C3 unit.
Generally speaking, we don't use office suite software...most are specialized
web forms using a special browser so knowing MS ir MSIE is not particularly
helpful. Most of the disaster relief software packages we see are not being
written using MS specific application interfaces.

Again, we DO NOT use untrained volunteers in our operations. We find that
untrained volunteers slow down and create bottelnecks in the communications flow
process. Therefore we give specialized training. In this case, any computer
use in a new learning process regardless of what previous computer experience is
had. Of course knowing how to type and use a mouse if important. But other
than that, its all a new process.
I believed that we have long harbored under the false notion that we can take
any ham off the street and make them a Ecomm or disaster relief communications.
Certainly the ARRL not any state of federal agency believes this. Thus the
stressing of EComm training courses such as offered by the ARRL and CERET training.

MT63 DOES NOT work better than MFSK16 in a keyboard-to-keyboard situation;
however, I haven't seen much need for keyboard-to-keyboard; rather, the need to
send rather large ASCII files.
Of course if propagation degrades to the point where MT63 won't copy data, then
MFSK16 can be used; however, you are forced to mannually type or if your
interface applications supports it, cut and paste of text into the MFSK transmit
window.

Again John, it matters little what the OS is since most of the applications are
not used by hams in their day-to-day ham communications.
But again, the bottom line is that something faster, not necessarly more robust,
that MT63 is desired. What computer hardware is used to accomodate the mode is
not in question.
