because DSD+ VC event log says some frequencies are Con+ and some are Cap+
Make sure you hit "F" when running DSD+ to refresh the system information while scanning DMR systems. It's better than it was but the software still takes a slight kick-in-the-butt in most cases.
So after you find a system and collect its information from DSD+ immediately after resuming your frequency scan then hit "F" while in your DSD+ window to remove the previous system's information or you may see misleading data.
I'm not sure if the event log data is "accurate" either.
