<div dir="ltr"><font style="" color="#000000" face="Tahoma,sans-serif">Jim,<br><br> The default is "usbinvert" only because it is configured for the Alinco, tyt etc. radios which go COS low on signal. If you have a radio that goes high on signal and you set it to "usb" you do have to be careful that you do not turn off or disconnect the radio. The CM108 has a pullup so it would put Allstar in an RXKEY condition and lockup a channel if you were connected anywhere. So the warning is to never turnoff or disconnect a radio especially in a connected state.<br><br>This is a warning I always give new Allstar users. We are looking into a SW timer to lessen the issue whether it is intentional or unintentional. <br id="FontBreak"></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">Date: Wed, 16 Dec 2015 03:02:17 -1000<br>From: jim.pilgram@gmail.com<br>To: arm-allstar@hamvoip.org<br>Subject: [arm-allstar] COR question<br><br><style><!--
