A noticeable 80mS or more of rf was still present after returning to receive. The delay is not consistent and varied greatly depending on the computer in use. This may not correct the problem for everyone so if you find my default settings or limits need adjusting please let me know.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Added to the Setup/Options tab are three controls that to help fine tune your radio. Enable PTT Delay will enable the PTT Delay up/down control. The PTT Delay control adds delay between the release of the PTT until the PTT Out line drops. The third is the MOX Delay up/down control. This allows the user to fine tune the delay between when the buffers empty and the dropping of the PTT out line. If this control is set to low the carrier will still be present at the output after returning to receive. I added the MOX Delay because of the vast differences noticed with latency in systems I used to test with.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>The PTT Delay is not active for the CW modes. Delay control for cw break-in is already present. The MOX Delay is active for all modes.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Also added was a display distortion fix sent to me by Joe, K5SO. Many thanks for that info.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>73, Doug W5WC<o:p></o:p></p></div></body></html>
