I have a brand new SDS 100 just out of the box. I have been monitoring ARMER daily since it went live years ago so I am familiar with trunking, etc. I used the Sentinel Software and the Radio Reference database. It shows it has the correct control channels in the system, but nothing heard. No signal strength shown and does not say "searching for control channel". I am assuming that it is a programming error or user error rather than a hardware issue. Would anyone be willing to chat with me about this?
