I use PSK / Olivia at the moment, by the end of 2006 RTTY and
computer-decoded CW (I am writing new digital mode software now).
What I look for:
* High dynamic range, at least 90 dB.
* Accurate clock (although software can overcome this).
* No inter-modulation.
* Quiet.
The cheaper SoundBlaster cards work well, an advantage of an external card
is no noise picked up from the PC. With the Delta 44 you can be sure that
the soundcard is not the weakest link.
