I have used this scanner for several years in a conventionl public safety system on VHF. Recently I moved to a county in Texas that has an 800 Mhz trunked system that, according to RR, may have recently been rebanded. I upgraded the firmware in the scanner to the latest version. I have located the system I wish to monitor and I have downloaded it with ARC from the Internet to the radio. All of the desired systems seem to appear on the scanner, however I detect no activity. I see the radio scanning the desired system. Using the ARC software I do not see the actual frequencies of the system. So, HELP, I am stumped as to what I am doing wrong. Any suggestions would REALLY be appreciated! Dennis
