I'll bite... I'm pretty sure that you have to point your receiver at a completely different part of the sky to verify that the signal isn't just
something bouncing off the atmosphere. Once that is done, my best guess would be to contact the actual SETI, not the ATS version. I would stay away
from NASA, as they are corrupt. You also may want to record the signal in every way possible, it will most likely go away sooner or later. I don't
know what else to tell you.
Good luck! I hope it's real, but I won't hold my breath. If you see an unmarked government vehicle outside your house, it's too late to run.
