If so follow the info on the DR1 mod in the howto's on the hamvoip.org web page to add additional gain by adding the internal op-amp into the circuit. It involves a couple of jumpers on the URI. I used 5V to power it from the 5V connection on the URI but if you need more gain you can run it from an external 12V source. On the DR1's I modified using 5V a setting of 950 on tx gain with preemphasis worked well.<br id="FontBreak"></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">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">From: k8it@cac.net<br>To: arm-allstar@hamvoip.org<br>Date: Sat, 17 Oct 2015 21:50:17 -0400<br>Subject: [arm-allstar] additional tx gain on RPI ?

<div>Is there any variable that I can adjust to get a higher level output on
transmit? it is not a receive level issue as all spoken outputs are very low.
like *70 for example. I ran my tx gain all the way up to 999 in duplex=2 but
levels are very low. I am trying to interface a RPI to a new Yaesu DR1X
repeater using an optional ARCCOM DR1X interface cable. All plug and play
no modifications to void the warranty of the DR-1X</div>
<div> </div>
<div>Just low tx audio!</div>
<div> </div>
<div>Also I noticed I need a longer delay upon tx keyup so the first part of a
message is not missed</div>
<div>is there such a variable?</div>
<div>TX KEY UP LEAD TIME=xxxx ? ;a delay after tx
keys up before messages etc start speaking?</div>
<div> </div>
