<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Isaac, </div><div><br></div><div>After conversations with Joe K1RQG I learned that historically PowerSDR was never intended to work using VOX with VAC so to answer your original question, the answer is: "No, PowerSDR is not supposed to support VOX with your USB headset." </div><div><br></div><div>With that information, I think I will not continue examining the VOX issue at this time. There are some actual bugs that need fixing in PowerSDR that I need to address that appear to be of a bit higher priority before trying to modify the original design to accommodate VOX/USB/VAC capability. Sorry. Maybe someone else would like to take up the challenge for you, or at least put it on a "wish list" to address later.</div><div><br></div><div>Good luck, OM! At least you do have an answer to your original question.</div><div><br></div><div>73, Joe K5SO</div><div><br></div><div><br></div><div><br><blockquote type="cite"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0px; font-size: medium; "><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1"><blockquote type="cite"><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1"><br class="Apple-interchange-newline">***** High Performance Software Defined Radio Discussion List *****<br><br><div lang="EN-US" link="blue" vlink="purple"><div class="WordSection1"><p class="MsoNormal"><span style="font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125); ">Hi,<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125); "><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-size: 12pt; font-family: 'Times New Roman', serif; color: rgb(31, 73, 125); ">I am using a wireless USB headset and it works fine.
