Recording DAX IQ O/P

I need to record the pure output from the DAX IQ O/P to investigate interference from the UK VDSL system using a software program Lelantos developed by Martin Sach. G8KDF.

Audacity will record from the DAX IQ O/P but unfortunately doesn't understand the IQ header which contains the tuning information from the radio and throws it away.

Does anyone know of another recording program that will take the pure DAX IQ O/P and save it in a .wav file.  Can be 8, 16. 24 or 32 bit.

Many thanks.  Dave G3SBP

    Dave,

    Did you get your question answered?     

    My suggestion is to use PowerSDR to record your I/Q  signals,  as long as it is not beyond 192 KHz in bandwidth.  Run in Demo mode ,  2.7.2 version is at - 

    https://www.flexradio.com/downloads/powersdr_v2-7-2_installer/?wpdmdl=3210&refresh=5ea2775a2862f...

     This will record directly to wav file , C:Users<your user name>MusicPowerSDR   , with the DAX I/Q , slice as the sound card input ,go to  WAVE tab at the top of PowerSDR ,  click "Record"   

    You should now has a wav playable file.  

    Hope this helps,
