I recently moved to the Charleston, SC area and am interested in purchasing a new digital scanner to monitor public safety, marine, and aircraft communications in Charleston, Berkerly, and Dorchester Counties. I am considering a Uniden BCT 15 but wonder if I should go all the way to a BCD 996T since a number of new trunket systems are scheduled to come on line within the next couple of years. I welcome advice from anyone familiar with scanning in the Charleston and with the proposed new systems. Thanks!
