I think it probably will work the other way. One of the ideas
with Linrad is to encourage people to modify the code and add
their own routines for controlling hardware or presenting more
information on the screen. This will be possible under Linux
only, but given the very low number of Linrad users, the
interest is pretty low now.

If Linrad becomes common among Windows users in the ham
community, I think an awareness of how easily one can
change it and give modified versions to friends should
encourage a lot of (particularly younger) hams to take
the challenge:-) Today they do not know what Linrad is, not
even that it exists.

Hmmm, I am opening the text files like this: fopen("foo","w") or
fopen("foo","r"). I have not noticed any problems other than
the usual one that Windows uses return and line-feed while
Linux only uses one of them.

OK. Actually it compiles under Linux only.

OK, but I write for Intel x86 only. Some code is in Intel assembly
(for multimedia instructions)

My goal is limited. I will make Linrad available as source code for
Linux (any distribution from RedHat 6.1 and upwards) and as an exe
file for Win98, Win2000 or WinXP. I am more interested in new algorithms
than making Linrad available on more platforms;-)
