Both nodes are configuredand working, and I have drawn a rudimentary drawing attached which showsthis configuration.Repeater is set up duplex=0 and linktolink=yes since it is tied to thecontroller, and works as it should with no problem. There is no issue onthis side at all related to my problem.When the link radio is set up duplex=0, linktolink=no, the node receives,and will transmit if the channel is clear, but it will not key up untilCOS/CTCSS is clear. Supermon does show the node active, but it does not keyup the radio.When the link radio is set up duplex=0, linktolink=yes, the node willtransmit over a signal being received. However, when it does this, theCOS/CTCSS remains active during the transmission, and does not clear untilafter the transmission is complete and the other system drops. It does passaudio, but if this happens while entering a DTMF command on the remotesystem (I have one set up for manual control of the link) the node willhang up in both Receive and Transmit until Allstar is restarted.I don't know if this is a behavior issue with the radio's programming, or aglitch in SimpleUSB, or what the issue is. I'm asking to see if anyone elsehas experienced this issue before. It is very frustrating.. in the firstconfiguration, traffic is missed if someone does not allow the link tofully drop. In the second configuration, it does what I need, but the stuckCOS causes lockups.Mike-------------- next part --------------A non-text attachment was scrubbed...Name: W8SOE.pngType: image/pngSize: 21103 bytesDesc: not availableURL: <http://lists.hamvoip.org/pipermail/arm-allstar/attachments/20201102/433e29a3/attachment.png>_______________________________________________ARM-allstar mailing listARM-allstar at hamvoip.orghttp://lists.hamvoip.org/cgi-bin/mailman/listinfo/arm-allstarVisit the BBB and RPi2/3/4 web page - http://hamvoip.org
