    I recently got an IC9700 and am trying to figure out how to do APRS. I am using a Mac and have tried numerous programs both on the Mac side and running windows with parallels. Using SoundModem, I can see that audio is going into the program looking at the waterfall and have tried both using audio from 144.390 and even using packet audio samples off the internet and I never get any decoded with any program I have tried. It seems like there must be some fundamental thing I am missing. I have looked at the various youtube videos and I just don't see what I am doing wrong.

    The IC-9700 has multiple options for what can be sent out over the various connections. With SoundModem, I have used the IC-9700 connected via USB. I had to set the radio to send AF over USB as opposed to IF for SoundModem to work.
