• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I have a old Pro-2004 that I used for many years and still works great. The NJ state police use a trunk system I would like to listen to. Can I just put all the voice channels used in my Pro-2004 and hear them? I know they might not be in order when the system switches to another frequency but I thought I might be able to hear some of it. I guess they are NFM also?

Thanks for the help

Well looks like they use 800 MHz Moto Type II, with some digital and some analog TG's. So you should be able to monitor the voice frequencies broadcasting analog TG's. You will basically hear continuous partial conversations from the Analog AND digital P-25 Talkgroups every few seconds. So you will hear the partial analog calls, but the P-25 calls (broadcast on the same voice frequency) will sound like engine noise.

Incidentally, if you get 2 $20 SDR dongles and suitable antennas along with Unitrunker and DSD+, you can properly monitor the system from your computer for dirt cheap.

If you are referring to the New Jersey Interoperability Communications System (NJICS) Trunking System then no. This is a digital system and the voice channels cannot be monitored using an analog scanner.

If you are referring to the New Jersey State Police Trunking System then it may be possible to monitor the voice channels in some locations. RadioReference states it is a Motorola Type II trunking system with both analog and P-25 voice channels. Some of the towers may have analog voice channels while other towers may have digital voice channels.
