Thanks Ken,

That did it. I have it all tweaked in now and the sound is much better. Not getting any complaints from the Echolink crowd any longer. I wasn’t sure where the 2 gain statements needed to be. I guessed wrong and had them in echolink.conf. So now I have that Hi Fi audio from GSM land ……..

well as I understand it - the  etxgain=  statement goes into rpt.conf, not echolink.conf.

and you probably need to do an asterisk restart to make it effective.

I have been happy enough with the default settings, but I am guessing if you have nothing in your node stanza (in rpt.conf) you will be 3 dB low on transmit audio.

Remember that E/L is GSM ... same thing they use on overseas cell phones. So if it like a bad overseas cell phone call, then you have it perfect.

Subject: [App_rpt-users] Audio Quality issues on Echolink

Has anyone had problems with very low outbound audio to echolink connections? 
The audio reports from the Echolink side are very thin audio, no highs or lows 
and low level. I have went through my RF link and also through Webtranceiver 
with the same results. If I do  parrot mode on my link, my audio sounds great. 
The issue seems to be in the interconnect to Echolink. Also I tried adjusting 
the link TX & RX echolink audio levels but I can't hear any change no matter 
what amounts of + or - gain I put in the etxgain or erxgain statements in the 
echolink.conf file. Any ideas???
