I asked about this as well and currently the files are not available to retrieve from the radio and save or send as an email. They are considering that for a future release from what I understand but nothing official.
The solution I have found to work is to use BB Flashback Express. A free screen recorder that makes it easy to upload to youtube or other places. This provide the audio as well as the panadapter so people can see what their signal looks like as well as hear it.
