It could be that they are doing either or both of these things, but normally they can be heard in the clear or at least with some digital decoding. The channels were alive and some minor bits of audio would leak through occasionally, but it was mostly 60 Hz hum and a steady carrier wave. That's not what I would expect from encryption, frequency hopping or spread spectrum signals. I even tried to listen through some repeaters in the area but got nothing but carrier on those frequencies. This was the case pretty much from the get go of the event. That's what seemed so peculiar about it.
