 You may encounter the following limitations with FreeDV 2020:
 
+1. It requires a modern (post 2010) Intel CPU with AVX support.  If you 
+   don't have AVX the FreeDV 2020 mode button will be grayed out. 
 1. Some voices may sound very rough.  In early testing
-about 90% of speakers tested work well.

 1. Like 700D, you must tune within -/+ 60Hz for FreeDV 2020 to sync.
 1. With significant fading, sync may take a few seconds.
 1. There is a 2 second end-end latency.  You are welcome to try tuning
    this (Tools - Options - FIFO size, also see Sound Card Debug
    section below).
