The gr-adsb package has a receiver example. Is there an example of a adsb transmitter? If not, how difficult would it be to convert the rx into tx? Would it be similar to replacing the USRP Source with a Signal Source and replacing the ZMQ PUB message Sink with a USRO Sink (this sounds too simp

Hello guys! Few years ago I implemented a ADS-B spoofer (transmitter) composed by an external python module that evaluates the ADS-B payload (given position information and aircraft ID) and a gnuradio OOT module that generates the waveform. I should share my code on github, let me know if you
