[App_rpt-users] DMK URI COS Level / Kenwood TKR-850

[John]

Wow, thanks for all the replies guys!I

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...

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.

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.

Got everything off the shelves and spread out now so let the
troubleshooting begin....
