Living in the islands and working for the power company, there are a lot of blips on the grid and switching power supplies take a beating because of that. I have an Astron and a Samlex in the 20 to 30 amp range that are both junk because of that. Put a meter on them and they look fine.. put a scope on them and load them and they go to hell. If you have a linear power supply or a big battery, give that a shot and see if the problem goes away. My 2 cents worth. </div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br></div><div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);">Jim NH6HI </div> <div style="width: 100%; font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);"><br></div> <div style="font-size: initial; font-family: Calibri, 'Slate Pro', sans-serif, sans-serif; color: rgb(31, 73, 125); text-align: initial; background-color: rgb(255, 255, 255);">Sent from my BlackBerry 10 smartphone on the Verizon Wireless 4G LTE network.</div> <table width="100%" style="background-color:white;border-spacing:0px;"> <tbody><tr><td colspan="2" style="font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"> <div style="border-style: solid none none; border-top-color: rgb(181, 196, 223); border-top-width: 1pt; padding: 3pt 0in 0in; font-family: Tahoma, 'BB Alpha Sans', 'Slate Pro'; font-size: 10pt;"> <div><b>From: </b>KH6KL</div><div><b>Sent: </b>Saturday, November 14, 2015 14:15</div><div><b>To: </b>app_rpt-users@ohnosec.org; Dave P; ARM Allstar; kh6kl@hawaiiantel.net</div><div><b>Reply To: </b>ARM Allstar</div><div><b>Subject: </b>[arm-allstar] Weird URI problem</div></div></td></tr></tbody></table><div style="border-style: solid none none; border-top-color: rgb(186, 188, 209); border-top-width: 1pt; font-size: initial; text-align: initial; background-color: rgb(255, 255, 255);"></div><br><div id="_originalContent" style="background-color: rgb(255, 255, 255);">

I'm not sure which board to post this on...</font></p>
<p style="margin-bottom: 0in"><font size="4">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.</font></p>
<p style="margin-bottom: 0in"><font size="4">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.</font></p>
<p style="margin-bottom: 0in"><font size="4">Note: I have
everything
working off of an Astron SS30 power supply. I looked for
ground
loops, but didn't find any.</font></p>
<p style="margin-bottom: 0in"><font size="4">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.</font></p>
<p style="margin-bottom: 0in"><font size="4">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.</font></p>
<p style="margin-bottom: 0in"><font size="4">I would like to know
if
anyone has had this problem and what was your solution.</font></p>
<p style="margin-bottom: 0in"><font size="4">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.</font></p>
