- Rick,What about comparing BER between the two? You may have noticed David Rowe added a BER indicator in FreeDV. Between that and SNR estimation, the performance of its modem can be evaluated by the user.Mel, K0PFX----- Original Message -----From: Rick MuethingSent: Tuesday, September 03, 2013 7:30 AMSubject: Re: AW: [V4Protocol] New file uploaded to V4ProtocolSigi,Yes that is possible...you can do a lot in software but it would be a much more complex Chat program and I’m not sure it is worth the effort.

Would it be possible to make one softwarew that can be switched between
Then comparing would be easier ... faste switch between modes and see what
works best ... (no need for that soft to copy BOTH modes together ... but
would be a nice add on)
