I just wanted to briefly make the point, for anyone else who might stumble across the post a few months late, like I did… that neither the FCC nor anyone else “set aside” 97.7 for the purposes of this event. The legal status of the broadcasts comes not from any special dispensation, but from their extremely low power, which is allowed under Part 15 regulations. This is approximately 50 milliwatts, which under the right circumstances can provide a weak but car-listenable signal for 700-800 feet. I wish that Part 15 allowed higher powers… but unfortunately, that’s just not the case.
