I have updated the firmware and did everything that is available. I began listening to hear the improvements, and couldn't tell any differnce other than one of my systems was worse. I still hear the machine gunning on the Kernersville System in NC, and the Forsyth County System the digital audio isn't as clear as it was before( sounds digital garbly all the time) . Are there any settings i can change to fix either problem. Some of this stuff is over my head and that's the reason i came to you all. Thanks for all and any help. If I need to tell you more just let me know.
