What I find amazing is there was no FM reception during the demonstration!?
If I understand the context correctly, the demonstration was held in Los Vegas? Sure it is remote (compared to say LA, NY, or Chicago), but as "large" US city it seems there would be more than 1 'powerful' FM station in the area. Powerful enough to get a signal during your demo?!
Or perhaps your hotel was especially well-shielded against EM-radiation?
Sorry if it sounds like I am being a sarcastic "hater". Far from the truth! I built radios as a kid and think this is really cool!! Just curious for the cause of failure...
