<DIV><FONT face=Arial size=2>Steve,</FONT></DIV>

<DIV><FONT face=Arial size=2>The below note is from the our last post
troubleshooting the ARIB/Asterisk-app_rpt for no receive audio.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>
<DIV>>>Download the ARIB schematic from zapatatelephony.org and check all
the<BR>>>op-amp outputs in the receive audio chain for audio with a scope.
Maybe<BR>>>you are missing the NO TS-64 jumper?</DIV></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Finally got around to do some more testing on the
ARIB. I've tested the output of the op-amps and they are working. The op-amp U1B
on pin 7 output is 241 milivolts and U1C output on pin 8 is 225 milivolts.
This is my adjustment from R8, the RX gain pot for now. The audio signal is
present in the receive chain. Also the NO TS-64 jumper is in
place. When I try to send dtmf sig's app_rpt/asterisk do not respond on
any of the local or remote commands. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also on the command line and its excecution,
with duplex=0 in the config file, I get not audio or ptt response but i do get
the screen action. When I change duplex=1 or 3, I get audio and ptt to the
repeater. In other words the transmit from the ARIB card is working but not the
receive sig that pass through the ARIB to asterisk for processing. Any
help will be appreciated.</FONT></DIV>
