We have several repeaters in my area using Allstar with that repeater with excellent audio. I assume you are using only analog FM on the repeater? Did you follow the mods I published on hamvoip.org?<br><br>simpleusb has very good audio and most problems can be attributed to the radio or settings. I believe the DR1 repeaters need both deemphasis and pre-emphasis set to on. Make sure both are uncommented and set to yes. <br id="FontBreak"></font><br><font style="" face="Tahoma,sans-serif">Exactly what is not right with the audio. Too many lows, highs, distorted?</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">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">To: arm-allstar@hamvoip.org<br>Date: Wed, 20 Apr 2016 08:08:37 -0500<br>Subject: [arm-allstar] Better audio?<br>From: arm-allstar@hamvoip.org<br>CC: wb9rsq@gmail.com<br><br>
<title>Better audio?</title>
<p dir="LTR"><span lang="en-us"><font face="Calibri">Sorry about the length ahead of time.</font></span></p>
<p dir="LTR"><span lang="en-us"></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">I just moved my simplex node to a DR1X repeater and have started to reconfigure much of my node.</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">Since I was using an older radio for the simplex operation I didn’t pay much attention to the audio quality.</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">However now as a repeater system under full allstar control I am quite unhappy with the audio.</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">Some things I don’t understand:</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">The differences and impact of the rx and tx parameters</font></span><span lang="en-us"> <font face="Calibri">between</font></span><span lang="en-us"> <font face="Calibri">the simple</font></span><span lang="en-us"><font face="Calibri">usb.conf and the simple_tune_usb.conf don’t seem to be apparent.</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">I toggled the preemphasis parameter in simpleusb.conf but it didn’t seem to matter much.</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">We added the amp power to the URI and at least that increased the level</font></span><span lang="en-us"><font face="Calibri">s enough to make the system usable but it also seemed to increase the background noise level going to the TX while keyed even with no audio.</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">Is there a way to add some sort of eq?</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">What parameters would increase the input so that output could be dialed back</font></span><span lang="en-us"><font face="Calibri">?</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">I’m including as input items for increase not only OTA audio but tones and local audio and of course allstar audio from external connections.</font></span></p>
<p dir="LTR"><span lang="en-us"></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">I am running the DR1X with squelch open and the node is ignoring ctcss and carrier detect. Can the allstar control get</font></span><span lang="en-us"><font face="Calibri"> either of these signals from the DR1X when allstar is the controller?</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">At the moment I’ve got quite a squelch tail!</font></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">I realize that I could go to the DR1X control mode or add some sort of other external controller but I really wanted to have allstar be the only controller in the mix.</font></span></p>
<p dir="LTR"><span lang="en-us"></span></p>
<p dir="LTR"><span lang="en-us"><font face="Calibri">Any help would be appreciated.</font></span></p>
