What kind of difference could hams expect to experience in practical useage of
this sound card with RTTY, PSK, MFSK16, DVK, etc. sound card applications
versus a "truly awful" sound card?
How do I know or find out if I have a "truly awful" sound card? A "Rightmark
Audio Analyzer" was mentioned as a test tool. But what characteristics do we
look for to separate the good from truly awful?
