This voice demonstration was taken off a microphone and an external speaker, voice quality is actually loud enough and clear.
There is a two to three second delay which we work through by saying over. Makes it less confusing.
Calls become purposeful and short, probably for the best since a continued connection with the bird is never to be counted on. That said, I have yet to lose a call in progress. Additionally, the Sat-Fi2 becomes more stable as the minutes pass, after ten minutes the connection remains quite good.
