| Hello everybody! Finally I managed to set up a GitHub repository with the code. I have to verify if that is the last version of the code. Please, stay tuned!

Thanks Ivan and John. Ivan I would like to see your spoofer if that's ok. Could it be converted completely into a grc simulation? John, I have no intention of broadcasting a signal into the air, I have the output connected to a spectrum analyzer. Thought it would be worth looking at. Thanks...

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 really need it.
Regards.
Ivan

I've used this package recently and it would not be trivial to convert from rx to tx. With that said, ADS-B is a pretty simple signal, I don't think it would be a monumental effort to do it. You would need to write the reverse of the decoder block that would create ADS-B messages from your input data. Additionally, you might need to write a block that converts that message to the Pulse Position Modulation used by ADS-B (I'm not sure if there are any standard blocks that can do this for you) and appends the preamble sequence.
I'm not sure what your application is, but I would make sure that whatever you are planning to do it legal where you are located. I'm not a lawyer, but I would imagine that you could get in trouble while building up your transmitter if other aircraft or flight controllers were able to pick up on your signal.
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 simplistic, but one can hope)?
