[amsat-bb] IC-9700 & FoxTelem 1.08p

[Alan]

Kevin,

I just played your recording through 1.08p.  Recovered 25 frames, which is about what you expect.  More evidence there is another variable involved.

73,

<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
