According to RRDB, that system is a) Smartzone, not simulcast and b) entirely analog (and so is NFM modulated, not CQPSK).
If that is not the case, then RRDB is incorrect and likely is passing incorrect system setup info to any scanner (or scanner user) reliant on it, which would result in unpredictable operation.
If you mean the Thomas / Dougherty system, according to RRDB: a) these are not simulcast sites (the kind subject to multipath issues that scanners of all ilk have issues with) and b) all the channels tagged for Dougherty County and Albany agencies appear to also be analog.
