As it says on this site "Some talkgroups on this system are using Project 25 Phase II TDMA modulation which can ONLY be monitored using a P25 Phase II compatible scanner". I am in Western Suffolk and have been using a Uniden BCD536HP and have already picked up some simulcasting they are doing for the 1st Precinct. So, I guess any current scanner that picks up Phase II TDMA would do it - I believe the Whistler TRX-1 or 2 would work, HP-2 and Uniden BCD436HP will work.
The only caveat is that I have read some rumors that SCPD will start encrypting (like Nassau County has) - if that happens, no radio will work, so consider that before spend alot of $$.
As always, If I have misstated anything, I am sure someone else will jump in to correct me!
