I listened to it from start to finish and the system itself worked very well. From where they were at, they were almost line of sight to Dans Rock with Mt Savage and Big Savage sites both just being a couple of miles away. The only issue I heard was firefighters trying to talk with their SCBA's on. Which to be honest, never worked well on analog either. I was monitoring with UT, and they hammered on the system pretty well, and didn't even come close to busying out the site.
