Thank you Alan for the time-saving information !
Actually I wanted to 'upgrade' from the simple soundcard to the available Signalink and now it is the other way round - hi.
Listening with the pc soundcard this morning produced good results.
And thanks for the link to OZ1PIF's impressive work !

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,

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
