The Uniden SDS100 is a handheld scanner manufactured by Uniden America released in Q2 of 2018 with an introductory MSRP of $699 It is the first scanner to incorporate I/Q technology and SDR (Software Defined Radio) in a handheld scanner. This provides superior performance scanning LSM (Linear Simulcast Modulation) systems. It uses the Uniden HomePatrol database and Uniden Sentinel Software for ease of programming. Its front panel interface and menus are functionally identical to the BCD436HP. Its most important new features include water resistance and customizable color LCD.
