<div dir="ltr">I would agree with Kevin. Every node I run is running DSP (with the exception of the RTCM's) and they sound amazing. From time to time it hear a "hiccup" in TX CTCSS mostly when monitoring with a motorola but thats it.

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 />
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 />
<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 />
