We have several repeaters in my area using Allstar with that repeater with excellent audio. I assume you are using only analog FM on the repeater? Did you follow the mods I published on hamvoip.org?<br><br>simpleusb has very good audio and most problems can be attributed to the radio or settings. I believe the DR1 repeaters need both deemphasis and pre-emphasis set to on. Make sure both are uncommented and set to yes. <br id="ecxFontBreak"></span><span style="font-family:"Calibri",sans-serif;"><br></span><span style="font-family:"Tahoma",sans-serif;">Exactly what is not right with the audio.
