"I see!", said the blind man.
What you are looking for is information for Amateur Licensing in
countries outside of the U.S. and a secondary topic of how could Linux
be helpful in obtaining a Ham license.
The first part would ultimately require you to research this question
for completeness in order to be accurate and not depend on hear-say. The
question of how Linux can aid anyone in obtaining a Ham license
would be that Linux has no great leverage over any of the other
operating systems in this matter. However, it can be used as an
alternative to the more popular Operating Systems.
Perhaps, a more relevant question would be how Linux can be beneficial
to an Amateur Operator compared to the other two popular Operating
Systems. For this question, you have already received a number of great
The best reason for Linux in Amateur Radio is one sited by others in
this thread and that is the fact that it can turn any old, retired,
Intel based computer into a working computer that sits by your Ham
console and is dedicated to your Amateur Radio needs. This relieves you
of the need to tie up your personal computer or families computer while
running Ham software such as fldigi, especially if your programs are
dedicated to being on line 24/7. this is where Linux/Unix shines. I've
had Linux servers running for more than a year without a hick-up or
having to re-boot now and then. I would never trust Microsoft Windows as
an unattended service.
If you wanted to get into the discussion of different flavors of Linux,
this would be one that starts with the original commercial and Open
Source development groups that slingshot-ed Linux out of just an
operating system for hobbyists into the main stream. It would also
include the genealogy of the current popular flavors and point out how
they differ and why they are similar.
Please forgive my verbosity, but I'm OLD and have volumes of verbiage
swimming through my head while trying to stay on point. Your question
has opened up a doorway to a whole discussion of Linux as evidenced by
others on this thread who cannot answer without opening up their minds
to the greater picture.
Again, good luck in your quest.
