There are diagnostic tools built-in to the soundmodemconfig program
that you can use.  Other than the scope.  Use those and a "mixer"
program to set your levels so that you get good decodes.  You'll
need to do that first before any program will be able to use it.

Did you do the "chmod 4755 /usr/local/bin/xastir" thing?  If not,
did you add the user that you're running Xastir under to the group
that the /dev/soundmodem device is under, or did you open up the
permissions on the /dev/soundmodem device?

As I recall you have to kill the soundmodemconfig program first,
then you need to start the device up, then start Xastir.  In SuSE I
have an /etc/init.d/soundmodem file.  I type "./soundmodem start" as
root and it starts up.  I can then add symlinks to the proper rc?.d
directories to get Linux to autostart/autostop the interface when I
boot or shutdown, or change runlevels.
