So I followed instructions from previous emails. I first went to my rpt.conf and did this rxchannel = usrp/127.0.0.1:34001:32001 Then Configure dmrlink.cfg in /opt/dmrlink/ambe_audio as a master Configure the repeater to point at the Pi as a peer. cd /opt/dmrlink/ambe_audio Test it by running python dmrlink.py in ambe_audio Watch the log stop dmrlink.py If you have rebooted DMRGateway should be running. Check it with ps ax | grep DMRGateway If not start it with /usr/local/bin/DMRGateway & Make sure asterisk is running and connect a node to it so you can hear it. start python ambe_audio.py Everything looks OK on the output, other than not hearing myself. I am also using TS2 TG2 which by the looks of the default ambe_audio.cfg in /opt/dmrlink/ambe_audio has TG2 in the filter. Is there any other ports I need to set? It looks like most things are set default.
