I use the Communication Specialists boards and they work well. You
are talking about $50.<br>

I have described the Allstar usbradio/simpleusb situation many
times but I will mention it again.<br>
<br>
Since the time I started in Allstar using Acid and Centos on PC's I
recognized a distinct distortion on many systems. The distortion is
variable, sometimes there sometimes note. It is usually always on
the transmit signal. That is the audio that goes out over the
Internet from the node. You don't hear it, others do. Also not all
systems do this and then not all the time. It also depends how many
DSP features you have engaged in usbradio.<br>
<br>
While the usual thought about cause is blamed on the processor
there could be other factors like inefficiently written code. That
being said the small board computers can and often do create
degraded audio when using usbradio. That is a fact whether you want
to go ahead and use it is your decision. I recommend not to because
we would like to keep Allstar audio the best audio out there in the
hamvoip community.<br>
<br>
We are also working on a possible fix for this in a V2 arm-allstar
release in the future and faster processors like the RPi3 may also
help. For now I would recommend using the external PL decoder for
the limited number of mostly commercial radios that do not have PL.
The simplesusb channel driver now has both pre and deemphasis so
you can feed the deemphasized audio from the radio to both the PL
decoder and Allstar.<br id="FontBreak"></font><br>

<div dir="ltr">Hello,
<div><br></div>
<div>I am trying to help a friend setup the latest RPi image of
arm-allstar for use with his GE Mstr II Mobile repeater. I
have run through the scripts and I end up with just static on the
repeater output. I can connect to other nodes but then I end
up sending static to them! </div>
<div><br></div>
<div>I suspect that this is a COS issue and I cannot get CTCSS
working using DSP. The default scripts do not list DSP as an
option for squelch. Since this repeater does not have a PL
board or a squelch adjustment knob, we need to have DSP handle it
otherwise the repeater just repeats static when activated.</div>
<div><br></div>
<div>Can this be accomplished on arm-allstar?</div>
<div><br></div>
