One of my three BCT8s is not working correctly. It is in trunk mode, working fine, when all of a sudden it will stop on a silent channel. When I use the arrow key or hold that channel and immediately release it in order to continue scanning, it starts stepping through the control channels without scanning talkgroups. This continues for several minutes until I start pushing the trunk and search buttons and eventually it starts scanning talkgroups again, only to have the same problem a few minutes later. It also seems to be having receive issues (which would explain the stopping on silent channels), but it was working fine until about half an hour ago, and nothing in the physical setup as been changed. Any suggestions?
