<div dir="ltr">Wow, thanks for all the replies guys!I<div><br></div><div>Mike: I've played with the logic in both states just to be sure. Nada inverted or not. I'm just getting back to this project after a number of months, so I'm sort of starting all over again. Just got everything pulled out of the motorhome so I can start digging a liitle deeper. IF memory serves.... the URI acts like it's loading the circuit. When not connected to the URI, the aux output on the Kenwood switches with received signal from 0 to 5 V or 5 V to 0 depending on how it's programmed. I'll try your suggestion of applying +5 vdc or ground to the URI...</div><div><br></div><div>Doug: No indication of change while monitoring the asterisk client. Checked to make sure I was set for repeater operation in the config files and all was well there too. </div><div><br></div><div>David: This is the same issue you tried to help me with several months ago but I still couldn't get things going before I hit the road for the winter - even with all of the great info you provided. I reviewed your notes again before tackling it again -- including checking all my wiring for the umpteenth time. Just wasn't sure if there might be some difference between your V2's and my V1. I'm just grasping for straws at this point. </div><div><br></div><div>Got everything off the shelves and spread out now so let the troubleshooting begin....</div><div><br></div><div>John</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, May 9, 2015 at 1:24 PM, Doug Crompton <span dir="ltr"><<a href="mailto:doug@crompton.com" target="_blank">doug@crompton.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
