Chris,
The 9700 outputs a 12khz IF signal that is passed to the internal
codec and then out the USB port and windows treats it as a soundcard.
I used audacity to create about a 2min file and then read it in on
1.07y to verify it is good.
I uploaded it to dropbox and the link is
https://www.dropbox.com/s/eh5bya72y8gfskt/fox1.wav?dl=0
it was recorded at 48000 and has been saved as a wav
Thanks
