<div dir="ltr"><font style="" face="Tahoma,sans-serif" color="#000000">It also works quite nicely on 5V as long as you do not exceed the P-P limit of the Opamp at that voltage. I use it with 5V on a system that needs a little more output punch and it works and sounds fine. Wire the opamp power source pin over to the 5V pin on the DMK. Give it a try. If it works it avoids anything external.<br id="ecxFontBreak"></font><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>> From: <a href="mailto:kk6ecm@gmail.com">kk6ecm@gmail.com</a><br>> Date: Thu, 23 Jul 2015 10:01:18 -0700<br>> To: <a href="mailto:app_rpt-users@ohnosec.org">app_rpt-users@ohnosec.org</a><br>> Subject: [App_rpt-users] DMK URI/URIx 6dB 12 VDC range?<br>> <br>> I'm wondering if the URI/URIx 6dB 12 VDC (pin 25) range will handle 13.8 (14?)
