<div dir="ltr"><div><div><div><div><div><font size="4">Hi,<br><br></font></div><font size="4">I am an newbie/oldbie who has been trying to get a successful Allstar repeater node working for quite some time. I have had success with creating many simplex nodes, but a reliable repeater eludes me. I can't speak with any authority to the USB audio issues, but I can say that switching from usbradio to simpleusb DID cure one of the problems I was having. The problem was audio would be completely distorted (including announcements and reset beep) - it sounded as though the audio was passing through a large window fan. Not every time you keyed the repeater up, but about 25% of the time. Switching to simpleusb got rid of that issue.<br><br></font></div><div><font size="4">When selecting usbradio, why is CTCSS mandatory in some manner? Why can't I just say "no to tone" and let the radio handle the decoding?<br></font></div><div><font size="4"><br></font></div><font size="4">My current project involves two Motorola CDM1250 radios on 220MHz as a repeater. Here is a list of behavior that I'm trying to resolve. Any suggestions would be appreciated.<br><br></font></div><font size="4">The repeater sounds fine when it first starts up, although I consider the audio to be a bit low. It will work just fine, pass audio, decode DTMF, etc., until it sits idle for an hour or so. Then you can kerchunk the repeater, it ID's just fine and the reset beep sounds normal, but it won't pass audio from one radio to another and it seemingly won't decode DTMF (watching in asterisk_cli). I can login via Allmon2 (Great Addition, thank you Tim) and have it say the time of day - it sounds great. It just won't pass audio. Reboot the machine and audio will pass just fine.<br><br></font></div><font size="4">I am certain that the computer is not going to sleep - all power saving is disabled in bios. I am also connected to the node via SSH at the time, so the computer can't be asleep. I have tried multiple computers, multiple cable harnesses, I have tried two different URI devices and a third URIx.<br><br></font></div><div><font size="4">I will say that I wouldn't have gotten this far without Doug Compton's excellent documentation from his BBB project.<br><br>73,<br><br></font></div><div><font size="4">Kevin<br></font></div><div><font size="4">W8KHW<br></font></div><div><font size="4"><br><br><br></font></div><div><br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Mar 27, 2015 at 12:46 PM, Jeff Carrier <span dir="ltr"><<a href="mailto:k0jsc.jeff@gmail.com" target="_blank">k0jsc.jeff@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">I would agree with Kevin.

Although there has been a slight improvement in usbradio in the
latest svn it still does not have the exceptionally clean audio
that simpleusb does.<br>

I have seen this statement from you many times. I have about 50
installations of usbradio where I don't experience these issues
you claim. Will you please quantify your statement as to whether
or not the issues you claim are for the BBB release, or any ACID
release - and also if it pertains to only the BBB or any computer
platform. <br>
<br></font></div><div bgcolor="#FFFFFF" text="#000000"><font size="4">
I have baseline performance specifications using usbradio and PC
hardware. While the performance does change slightly due to the
exact radio adapter device, the overall response and distortion
specifications are very consistent when using G.722 -u-law. My
performance specifications show that any distortions or response
issues contributed directly by app_rpt, any channel driver, or the
radio interface are well below detection by the human ear. In
fact, I can guarantee you that more distortion is generally
experienced when running simpleusb audio through any radio. In
other words, there is more distortion and response issues because
of the radio then from this application and its supporting
hardware in usbradio. <br>

I'll apologize that I had to hijack this thread from the
arm-allstar email group and re-post it here - because I'm no
longer allowed to participate in your group directly.<br>
