I live in Baltimore City and listen mostly to Baltimore City and County Police and Fire and VHF air and marine. I currently use Uniden SDS 200, BCD536 and BCT 15X scanners. Based on reading threads I am curious about trying a Unication pager. However, I have no idea where to find a vendoe for the pager and associated programming software. If anyone can suggest some vendors I would appreciate it. Thank you.
