I had also posted this story earlier, then deleted it once I learned that. However, I did find this interesting doc about real ADS-B spoofing, which does not appear to be very easy:
Man, I wrote that comment at the end of a 14hr work day. The crazy thing is that I had seen that SDR slide when I first looked at this. Hours later, when I posted the comment, I reviewed it again and completely hallucinated the SDR slide away.
I need to check all the work I did towards the end of yesterday. Valuable lesson. Thanks.
