What makes VARA so effective is the multitude of modems and other techniques such as variable FEC, negotiating with the other station, channel sounding, etc. That may well require a multitasking OS.</div><div dir="auto"><div dir="auto"><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br></div><div dir="ltr">Steve Stroh N8GNJ (he / him / his)<div>Editor<div>Zero Retries Newsletter - <a href="https://www.zeroretries.org" target="_blank">https://www.zeroretries.org</a></div><div>Radios are Computers - With Antennas!</div></div></div></div></div></div><div><br></div><div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Oct 6, 2024 at 20:44 Jason Rausch <<a href="mailto:jason@ke4nyv.com">jason@ke4nyv.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-style:solid;padding-left:1ex;border-left-color:rgb(204,204,204)"><div><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif;font-size:16px"><div style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif"><div dir="ltr" style="font-family:"Helvetica Neue",Helvetica,Arial,sans-serif">I could get behind VARA if they would open up the spec so we can implement it in a hardware modem, thus eliminating the need for a full Windows computer to run it.
