Got it all setup tonight and did some testing.

DMR to ASL sounds great! For some reason ASL to DMR sounds crunchy.

I was looking at the DMRGateway.ini and changed some of the settings and it improved it a little.

Mike and/or Steve, Can you explain these a little more?

aslAudio = AUDIO_USE_AGC ; Audio to ASL (AUDIO_UNITY, AUDIO_USE_AGC, AUDIO_USE_GAIN)

agcGain = -20 ; Gain (in db) of the AGC filter

dmrAudio = AUDIO_BPF ; Audio from ASL (AUDIO_UNITY, AUDIO_GAIN, AUDIO_BPF)

dmrGain = 0.35 ; Gain factor of audio from ASL (0.0-1.0)

I have attached a couple wav files of the audio

Assuming existing install

cd /srv

mv DMRGateway DMRGateway.old
git clone https://github.com/N4IRS/DMRGateway.git

cd DMRGateway
mv /etc/DMRGateway.ini /etc/DMRGateway.old

Assuming you are running a RPi2
cp DMRGateway.armv7 DMRGateway

./install.sh

cd /srv
mv ambe_audio_2way ambe_audio_2way.old
git clone -b ambe_audio_2way https://github.com/n0mjs710/DMRlink.git

cp dmrlink.cfg /opt/DMRlink/ambe_audio
cp dmrlink.py /opt/DMRlink/ambe_audio
cp template.bin /opt/DMRlink/ambe_audio

Edit /etc/DMRGateway.ini to taste
Edit /opt/DMRlink/ambe_audio/ambe_audio.cfg to taste
Edit /opt/DMRlink/ambe_audio/dmrlink.cfg to taste
