All digital transmit is easy and has been done with FSK, BPSK, OOK, and numerous other K's by many people lots of different ways. We do this as a class exercise at 228 MHz using a Digilent FPGA board (Nestor, J. A., & Nadovich, C. (2009). An FPGA-based wireless network capstone project. In 2009 IEEE International Conference on Microelectronic Systems Education, MSE 2009 (pp. 53–56).) Much more difficult is all digital _receive_ as you need to conquor the selectivity and sensitivity problems. It's
