<br>I had a note up and running well with not any real issues, however after about 4-6 months, the system no longer detected carrier on the cor line.<br><br>Sometimes it would think its always on and sometimes it would think its off.<br>
<br>I checked the voltage at the line from the radio and that was working as it should.<br><br>I even reprogrammed the radio to try it voltage high instead of low for carrier. This did not make any difference.<br><br>I have tried several radios Radius M100 CM300. All work fine on the IRLP machine and all show proper voltage on the COS signal. <br>
<br>I have the DMK URI with the eprom. <br><br>Can anyone suggest any other diagnostics? I would like to get the Node back up and running and/or order a replacement URI<br><br><br>Craig<br>VA3DTF<br><br><br><br>
