<p dir="ltr">Hi All,</p>
<p dir="ltr">I have just setup a RPi2 & URI combo and it work quite well. Except it has quite a high noise level on the tx.</p>
<p dir="ltr">I noticed that this was also the case on the beagleboard xm and lox board combo as well. I was hoping it was peculiar to that hardware but it is not unfortunatly.</p>
<p dir="ltr">Basically it sounds like it is being encoded with gsmĀ and being compressed with noise added to it.</p>
<p dir="ltr">If I connect via IAXRPT the signal is quite clear but not perfect so there is a little bit of noise on the input but it is the output where it is degraded again.</p>
<p dir="ltr">I am using Simoco SRM9005 radios using the rear io on the db15.</p>
<p dir="ltr">Could someone shed a little light on the audio path through asterisk and where noise could be coming from there?</p>
<p dir="ltr">This is for an ultra portable repeater that is carried up hills for events and I have found that apt_rpt and asterisk is awesome because it is a complete voip switch. Keep up the good work.</p>
