ARC XT or ARC XT PRO from Butel can be used for these 5 Uniden Scanners: BCD396XT/BC346XT/BCD996XT/BCT15X/BCD325P2/BCD996P2. I have used Butel ARC software for all my scanners for many years and very happy with it.
Besides those, ProScan supports the BCT15, BC250D, BC296D, BR330T, BCD396T, BC780XLT, BC785D, BC796D, BC996T, as well as the BCD436HP & BCD536HP series.
While ProScan, @ $50.00, is more expensive than ARC-XT Basic ($39.95), it includes logging, recording, and virtual control. You have to go to the Pro version of ARC-XT, $69.95, to get that. Both programs offer free lifetime updates, and both have a 30-day free trial period so that you can try before you buy.
