[App_rpt-users] URI loopback testing

[Jon Rorke]

I find that if the tx audio settings are close to the edges of 
adjustment for the URI then you get Allison distorted.

First I would preset the input and output audio pots on the controller 
for 1 v p-p if possible. Then set the tx and RX audio on the URI.

If that still has distorted audio you may need to take out the audio 
boost or put it in, then re-cal the audio levels on the node.

If all else fails, then in usbradio set txprelim=yes and re-cal the 
audio in the node.

These steps should easily take care of this issue.
