One in the user’s receiver which can be eliminated by using tone squelch and turning off the PL some time before dropping the carrier. Some commercial rigs respond to the reverse phase tone burst. That is unusual in amateur rigs I think. And some amateur rigs require the tone to be turned off longer that the app_rpt default. This all has to do with the squelch tail being generated in the user’s receiver. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>But if you want the *repeater* not to transmit a squelch tail - from its own receiver - then you need:<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Rxsquelchdelay in usbradio.con <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>as previously discussed in :<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><a href="http://ohnosec.org/pipermail/app_rpt-users/2014-April/009175.html"><span style='font-size:12.0pt;color:windowtext;text-decoration:none'>http://ohnosec.org/pipermail/app_rpt-users/2014-April/009175.html</span></a><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>for example<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>rxsquelchdelay=50 ; delayline in ms, carrier squelch tail eliminator<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>this requires use of the usbradio channel driver.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>73<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'>Ken<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> R.

Our coordination requires that we don’t. It appears that the MSF has a fixed squelch tail elimination method an no control other than cranking up the squelch again. This is surprising since we use PL encode / decode. I would think that the PL would mute as soon as the user unkeys.<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri",sans-serif;color:black'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri",sans-serif;color:black'>With this said is there anything in Allstar that would help with this situation?<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri",sans-serif;color:black'> <o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-family:"Calibri",sans-serif;color:black'>Wayne<o:p></o:p></span></p></div></div></div></div></body></html>
