My IRLP computer finally gave up after some 10 years, it was running CentOS 5, I decided to go the Pi route.
Following the instructions all was going great and now I get an ERRORCODE 40, I am NOT a fluent Linux user, I manage to a certain point.
I ran the IRLP troubleshooting script and I passed all the steps except the EchoIRLP "That's OK as that part is not important for me at this time"
I was able to adjust the TX level and it TX the NODE ID.
I am using a Pi 3 B+ and loaded the latest Raspbian Buster Lite and also using the recommended SYBA USB sound adapter.
Any help or direction is appreciated,
