I record the audio from the external speaker port on my Icom IC-706MKIIG into a Sony audio recorder in the wav format. Then I transfer the file to my computer and play it in Audacity and use a virtual audio cable to feed it to FoxTelem.

Mike, regarding your question about using a known good recording, you could probably pipe my YouTube video into FoxTelem and decode it, and for sure you can use my actual recording:

Mine is not a great recording compared to ones that had automatic frequency control to accommodate Doppler shift, but I did get 49 packets out of it! Make sure you disable "Upload to Server" in Settings > Decoder Options, before you decode it or else you'll get credit for my "work" ;-) Also, the recording only has useful audio after the 6 minute mark.

I don't know about recording it with a microphone/speaker or even hardwired from a radio. Anyone have any experience with doing it that way?
Paging KG4AKV...... How did you record the audio from your 706MKIIG? (John posted a youtube video of him decoding a recording successfully, but not sure how he recorded it).
