Werner,

I have had exactly the same results, and yes, 48 kHz is correct according to
the program author.  Based on reports I have received, and considerable
experimentation, it seems to be a poor performer in this mode.  So far,
nobody has reported success with the unit on any radio.  Other cards work
fine, even holding a microphone in front of the speaker.  There is nice
discussion here about both internal noise and non-linear response issues,
and some fixes here:

I am retiring the unit, so will not be trying these modifications to see
whether that helps.  From reports I have received, a simple audio patch
between the rig and a standard soundcard works well.

73s,

Subject: [amsat-bb] ARISSat TLM: Sample rate of Signalink

While I have been decoding some frames in an earlier pass using 
another pc, I have no luck using the Signalink USB attached to to 
AF-Port on the IC910H (cw decoding works very well)

How can I verify it's sample rate and - if necessary - set it to 
48 kHz ?

thanks
