Good questions - With the right software, even a "truly awful" soundcard
will print RTTY that you can't even hear. Maybe with the SC we can print
stations that aren't even operating! HI Just kidding - looks like a good
soundcard choice.
Anyone tried the WriteLog sound checker on a Santa Cruz? I don't see it
listed in my soundcard survey results at
