[App_rpt-users] Weird URI problem

I'm not sure which board to post this on...
My repeater is a Motorola R1225, 25Watts, w/ PL. The computer is a
BeagleBoneBlackC. I'm only using the COS, PTT, Rx Audio, Mic and ground.
This system has been working on the AllStar Network since May 2015.
About 2 months ago a weird problem started: The Xm hangs on, but PTT
voltage is at 5v. The URI red led is off. If I just wait the timeout
timer kills the Xm but the the PTT doesn't work until I reset the 1225.
The Rptr Rx led is off the whole time, so there's no incoming signal.
This only happens when the URI is connected to the accessory plug. I put
my spare R1225 on-line and the same thing happens.
Note: I have everything working off of an Astron SS30 power supply. I
looked for ground loops, but didn't find any.
I borrowed an URI and the system worked perfectly. I returned the URI
and put the repeater on-line/stand-alone for two weeks with no problems.
I sent the URI back to DMK engineering and it passed their test, so it
was returned to me. I put it on line and the same problem started again.
I swapped the the two URIs and my machine worked perfectly but the other
machine started to kerchunking by itself. I returned the borrowed URI,
and put my machine on-line/stand-alone.
I would like to know if anyone has had this problem and what was your
I called DMK engineering to see if they would warranty the URI, no
decision yet, but I ordered a new URI to get this node working.
