What's the legality surround security research like this with ham radio? I was under the impression that the airwaves are highly regulated and those regulations could hamstring (forgive the pun) security research, but I also know next to nothing about it.
I'm not a lawyer, but I used my real callsign when doing anything over the air. I used known protocols, no encryption, nothing commercial, etc. This was all against my own lab systems. I don't think I crossed any legal lines here. It probably would have been even better to use some kind of dummy load to further reduce the range of my transmissions but I didn't have anything like that to use at the time. I just kept my power as low as I was able.
