$349 at the manufacturer’s site so this is a good deal. It has digital P25 with auto tracking, so it’s good for monitoring government systems which use that standard.
From the manufacturer:
Automatic Adaptive Digital Tracking - When monitoring P25 digital systems, instantly adapts the digital decoder to the digital modulation format of the transmitted signal, then analyzes the signal over 50 times each second and adapts to any subtle changes caused by multipath or fading. No cumbersome manual adjustments are required.
P25 NAC Functionality - P25 Network Access Code (NAC) is used to provide selective squelch operation on conventional digital channels. Your WS1040 will detect the NAC that is being used on a P25 conventional digital channel, and allow you to program NAC codes to block transmissions that do not have a matching NAC, including analog traffic on the same frequency.
