I don't think the Charles County system changed (yet). MdTA is primarily on the new Maryland FiRST Phase 2 system (First Responders Interoperable Radio System Team (FIRST) Trunking System, Various, Maryland - Scanner Frequencies
) that went live the end of 2012. However, since there is limited or no coverage in some areas (Charles, Montomery), MdTA in those areas are relying on the local juridiction's trunked system for now (to my knowledge).
However, it is true that the Maryland FiRST system suffers from the LSM issues -- essentially all new digital systems/upgrades seem to have this problem for scanners
In Maryland, at least these systems have this problem making them all difficult to monitor:
Prince George County
Kent County (on Maryland FiRST)
Frederick, Washington and other counties may also need to be on this list.
Take a look at the some of the threads in the Maryland section of RR for these systems and you'l find alot of discussion about the problems scanner users have experienced and the efforts some are making to try to overcome it.
