GSP--Which Sites?

[nyscan]

I frequently make the run on the GSP from the NY line to LBI. Which sites on the NJSP TRS should I have active on my Pro-668? Also, is it best to create a separate system for each site? Thanks.

Toll Road Patrol Operations Talkgroups:

2-COMM Parkway North (MP 131 - MP 172)
3-COMM Parkway Central (MP 89 - MP 131)
1-COMM Parkway South (MP 0 - MP 89)

You would want to program in the North Simulcast, Central Simulcast and South Simulcast sites.

Do each of the 3 talkgroups simulcast on all 3 sites?

Do each of the 3 talkgroups simulcast on all 3 sites?

Believe they all simulcast on Troop C since it is in the coverage area of all 3.

So, if I only have one of the TG's programmed will I hear it as long as I am within range of any of the 3 sites?

NYSCAN I am not familiar with the 668 but in your case I suspect you only want to hear the talkgroup that pertains to the area of the GSP that you are driving? So if you are coming down the GSP from the north you only want to hear 2 com? Then as you get to MP 131 you then want to change over to 3 com? Or do you want to listen to all 3 the whole way down to LBI? Perhaps one way would be to program 3 banks, each with only one system and one talkgroup related to that systems area. So perhaps bank 1 could be Troop B with 2 comm and that covers your northern section of your trip down to MP 131. Then bank 2 could be Troop C with 3 comm and then lastly bank 3 with Troop A and 1 Com.

Other thought is to still have 3 banks with each one having a different system but have all 3 talkgroups assigned to each bank so you can hear everything on the GSP as you move from system to system just turning off one bank as you turn on the other

Last thought would be to program all 3 systems control channels and 3 talkgroups into one bank and as you lose one control channels signal the scanner should pickup up the next best and allow you to just use one bank in the scanner and not have to change anything as you drive that whole length.

What I described would work for NJICS 800. For NJICS 700...you would probably want to know the exact sites and do it that way but would have to keep in mind that the 700 system is a mix of simulcast and multisite so you probably would not hear 1 Com up north but only as you got closer to LBI and vice versa...

Using my 436 is a little easier for me since the GPS will dictate what sites I exactly scan so I dont have to change anything. The scanner roams pretty close as to what their radios would do. As I said I dont have enough experience with the 668 so not sure how it actually operates

Thanks Ed for the detailed reply. Yes, I am interested in the radio traffic for where I am on the parkway. I understand the areas that are covered by the different TG's. On the Pro-668 you can select which sites on the NJSP system that you want to monitor. Now here is where my understanding of the NJSP system is a little weak. First I am looking to find out geographically which sites I should select and also as an aside would all 3 TG's broadcast from each of the sites. Hope the question makes some sense since I don't have a great grasp of this particular system. Thanks.

As was noted above, on 800; all sites carry the same information (simulcast) so if you were to put in one system (troop B) and just the talkgroup for 2 Com, that would allow you to hear just the north area of the GSP on the system that only covers that area geographically. You would then need the Troop C system and 3 Com loaded just for the central part of the state and then Troop A with 1 Com for the southern section of the state.

I would not worry so much about which sites if you can but more about the 4 control channels being loaded for each system. So what you could perhaps do is just have 1 site loaded with the 4 control channels and just the one talkgroup in 3 separate banks for each area. Call the site whatever you wanted to.

Now for the 700 system they have, yes you would have to get much more detailed placing the frequencies in for the specific sites that would be near the GSP where you are traveling and thats where Radio Reference comes in handy for loading of course and actually it would just be easier to load all the sites in let the scanner find the sites with the strongest signal versus selectively placing only those sites close by. Even though I site home most of the time scanning I just keep all the sites loaded and let the scanner find the strongest signal or in some cases as with 700 the site with the conversation I am tracking which in some cases can appear on a different site than the one I was listening to prior with another talkgroup...thats the nature of multi-site versus simulcast.

But for your situation I would opt to go with the 800 side of NJICS, load the control channels for all 3 systems and load the 3 talkgroups for the regions and then you can lock or unlock the talkgroups as you travel along...or perhaps just leave all 3 talkgroups on so you can hear whats up ahead (or behind you)

Thanks again Ed. I think I got it this time. Will try your suggestions. Should do it for me. If not, I'll post again.

Not a problem. I know its hard to visualize it from words on a web page but if you still have problems let me know

 

[ansky]

So let me see if I'm understanding this correctly. I live in North Jersey (Essex County), so I have the North and Central simulcast sites programmed into my scanner. So you're saying I should still be able to hear the Troop A (South) talkgroups because they are simulcast on the Troop B and C sites?
