the reason FPGA's are so common, particularly in TX scenarios
is that time constraints for low level protocols are extremely
tight. there is a non-trivial amount of latency for a round-
trip to the bus, and then operating system is non-real-time.
if you are receiving only, then this becomes less important
so for your use case, maybe just downcoverters and RTL-SDR?
keep going! you'll only make it better :)
