Thread-topic: VLF: Clipping or blanking??
Hello agn, 
 
Hm, maybe the audio driver is a bad one. I had to set up this PC new (win XP) 
and lost the audio driver. I found a new driver in the web that should be 
suitable for this mother board but maybe it does not work sufficiently up to 
48000... I will check this later with my alternative USB soundcard...

Stefan,

No, unlikely, since it appears where a mirrored signal of DHO38 should
appear at a sample rate of 44 kHz. I don't think that's accidentally.

May be there's a re-sampling process elsewhere in your software.

How to lock the sample rate of a sound card against a MSK modulated signal?
 The only idea I have is to demodulate it and locking a re-sampling process
against one of the two carriers - by software. May be there's the key.
