I heard this as well on some of my visits to Vegas... when the audio co-operated, it sounded pretty decent really, but the Max Headroom events were endless.
I remember listening to Las Vegas Metro when they were still on Open Sky and rebroadcasting over the VHF channels. The patrol officer’s transmissions would get stuck for a second or two in sort of a Max Headroom stutter. Must have been very frustrating for the dispatchers.
