I have successfully installed fldigi on the Raspberry Pi 3B+, and it
receives fine, but I finally learned that in order to tx, the device
file should be /dev/ttyUSB0. I have unsuccessfully tried the
instructions in the KK5JY manual which is nicely written to build the
/dev/ttyUSB0. I don't need rig control since the rig is a Icom 737,
and I am using a Signalink USB sound card. Help! Does anyone know the
proper way to get /dev/ttyUSB0 done? I see that many of you are using
the Rasp 3B+ with the Signalink. What is the trick??
