I haven't seen the latest version of OO, but the versions I've used do odd
things with some Word documents. I'm running the Codeweavers' Crossover
package with Microsoft Office 2000 for compatibity with those bound to
Windows systems. While Office itself can be expensive (although I got mine
while I was a student [again] doing my masters' degree recently - I'd never
use it enough to justify the price tag of the non-academic version otherwise),
running it under Linux is a lot safer (virus-wise) and cheaper than running
it under a Redmond OS.

Fortunately, it's not necessary to learn how to use Linux to use it in
that kind of environment. If the system's set up and maintained before
the emergency, it can be totally turn-key during the emergency, and the
user doesn't know/care what OS is running the system. Putting the
needed programs on a toolbar makes them a click away to even an untrained
user.

Get back to the KISS principle. MFSK will out-perform MT63, but requires
a lot more operator intervention. MT63 can just be left in a monitor
state and watch the monitor for activity. Olivia is even better in this
regard. By the way, when the dust finally settles and we are HOPEFULLY
able to used mixed-mode voice and digital modes on HF, it'll be awfully
nice to be able to coordinate things on SSB and kick on 2 kHz MT63 or
something similar to pass a data file. Not legal in the US now, but
hopefully will be some day.

It runs well under Windows, too.. just not "pretty" or convenient. The
waterfall isn't really needed, particularly for fixed-frequency operation.

Which gets to the comments below...

Sorry to disagree with both Windows and Linux zealots -- but there is
no need to select any operating system to RULE in the emergency
computer world. Whatever suits the needs -- including performance,
training, reliability, adaptability, and budget -- is what should be used.
An open architecture where any/all OS's can be used is best. Computers
should be able to interoperate via standard ethernet networks, to allow
file sharing/transfer between systems, and use non-proprietary products
that can be used by different systems with different OS'es without having
to worry if the system can handle some oddball format.
Standardize on protocols and interfaces, not on products, and especially
not on the things that are required to support specific products. If you
do that, the pieces can be put together 'on the fly' as needed, fitting
into the 'bring your own equipment to the emergency' paradigm.

Then do we get to fight about whether we use KDE or Gnome on the
desktop? It's time to figure out how to make them all work together, so
that it is no longer important what OS is under it all. Building up
a system that's incompatible with other systems is suicidal, regardless
of if it's based on Linux, FreeBSD, OS/X, Windows, .NOT or whatever.
Which gets back to the questions like "why do we have so many modes?" and
such -- the idea is to have a variety of tools to use when needed, and to
have the expertise needed to not only use them, but to know which one to
use in a particular situation. Arguing over Pactor vs MT63, Windows vs
Linux, and with how many tones and what bandwidth do we use Olivia can be
counter-productive. Keeping the discussion focused on learning the
differences -- and the advantages and disadvantages of each -- can be
educational.
