If you are already doing that and have very low audio then I guess yours is different for some reason. Also if you are using 5V to power the additional amp you could try running it from the suggested 12V. In that case you would need to use an external voltage to the opamp pin on the DMK-URI. Refer to the DMK web site for schematics and suggestions. Using 12V you should be able to develop more than enough audio.<br></font><font face="Tahoma,sans-serif"><br></font><font face="Tahoma,sans-serif">Let me know what you finally find.</font><br><br><b><font style="font-size:16pt" size="4">73 Doug</font><font style="font-size:16pt" size="4"><br></font><font style="font-size:16pt" size="4">WA3DSP</font><font style="font-size:16pt" size="4"><br></font><font style="font-size:16pt" size="4"><a href="http://www.crompton.com/hamradio" target="_blank">http://www.crompton.com/hamradio</a></font></b><font style="font-size:16pt" size="4"><br></font><br><br><div><hr>From: <a href="mailto:kd0qcn@aecimo.org" target="_blank">kd0qcn@aecimo.org</a><br>Date: Sat, 19 Dec 2015 22:29:08 -0600<br>To: <a href="mailto:arm-allstar@hamvoip.org" target="_blank">arm-allstar@hamvoip.org</a><br>Subject: Re: [arm-allstar] Yaesu DR-1X Interface<br><br><div>Hey Doug and All,</div><div><br></div><div>OK, here is where I am on the interface, I followed your how to on hamvoip, the only thing I did different was I am going high on COS polarity because I didn't have the items necessary to do it and I'm an hour away from the nearest radio shack.

I did read the howto on <a href="http://hamvoip.org" target="_blank">hamvoip.org</a>. I was really wanting to use
the 15 pin connector on the back of the DR-1X. You stated in the
howto that you did not have access to the DR-1X and you were unsure
of how to interface with that 15 pin. That is what I'm trying to
figure out as we are trying to avoid cutting into the main harness
inside the repeater. Really all I need is something as simple as
pin 1 of URI to pin 2 of DR-1X etc... I was hoping someone had done
this already as I hate to re-invent the proverbial wheel.<br>

Allstar and interface that with our DR-1X repeater using a DMK
URI. The problem I am having is I am seeing some information
on the DR-1 interface but not on the DR-1X. The DR-1X uses the
15 pin plug on the back of the repeater. We are not concerned
with keeping the digital side of the repeater at this point.
Has anyone done this interface and might possibly have the
schematic of how you did it, or even something as simple as
what pins you used?<br>
