Purchased an SDS 200 hoping for improved simulcast performance on the the Charlotte UASI system. However, I am struggling. I have programmed the SDS200 with the latest database info from Radio Reference. When scanning a department (eg: Charlotte Fire) I can pick up the main dispatch (Alarm) fine. However, I do not hear the transmissions on the assigned channels when companies are dispatched. If I put the SDS200 in hold mode and scroll to the appropriate channel I can hear the transmissions of the companies fine. The SDS 200 is just not stopping on the channel as it scans. My 996p2, BCD325p2 and Unication G5 all receive the traffic on the operations channels perfectly siting in the same spot. Looking for any suggestions. Thanks in advance.
