Yeah, my audio archives only logged 9469 once with a 3 to 4 second bit of audio and that was it. They refereed to a mile marker and something else related to a road. That was it. I monitor it now in my group of "unknowns" so time will only tell if I ever hear anything again.
what blows my mind is just how much traffic is " missing" but again they have had not much in the way of fires this season we occasionally hear them doing traffic and or weather items in the clear, have not paid attention to the TG
