I monitor East Brunswick as my own local . It is my understanding that they are developing a capability for selected digital capabilitiies within the police. I have not heard any digital as yet on any of the TG's - including the radio techs. The displays here of A or D, I believe, are projected for the future. How far in the future, who knows. Hope this helps.
EB TRS may be listed as an Astro system because the FCC license was modified to allow digital transmissions (voice and data). I have tried to submit corrections to the actual talkgroup usage (analog versus digital) a couple times with no success or response.
I think digital encryption has been used part-time on the EB Detective talkgroup. I have been told it has also been used on the SRPD 3 TG, but I'm not aware of digital (enc or clear) anywhere else and I can't even confirm those two.
