The files are not split into .cpp and .h files. The main file ubitxxxx.cpp will have the main routines to control the radio, initialization and main loop. The user interface is implemented in ubitx_ui.cpp, the code for setup/calibration routines is in setup.cpp. Nano gui, keyer, morse.cpp (morse reader) are all libaries that have minimum dependencies on each other.
