NYPD is still analog, for the time being.
The WS-1040 is a P25 capable scanner, so it will work fine with most stuff in and around NYC, including most of the public safety trunked systems (NYC DoITT UHF, NYC DoITT 800 MHz, State of NY Metro-25, Port Authority EDACS, etc.)
It will not decode DMR (MotoTRBO), only P25.
Note that the new DoITT P25 trunked system is P25 Phase II (TDMA) capable, so the scanner may not decode all future talkgroups on that system. The new P25 system the Port Authority is building out is also Phase II, so the WS-1040 won't be able to decode those talkgroups either, assuming they are not encrypted.
