Help programming a few P25 conventional channels

[bobruzzo]

I want to include a few local stand alone conventional PD freqs. But I am having trouble with the "Conventional group ID settings" and "TGID grouping list"......attached is what I have so far in the CPS. I am sure the data is correct in the first two bottom pics. The problem is I dont know what the talk groups are for these users. There is nothing listed in RR for conventional P25 talk groups. Here are the 5 channels I want to set:
(Mass.) Fall River PD 1 482.3625 NAC 676
(RI) Cranston PD 3 482.5625 NAC DEF
(RI) Cranston PD car-tocar 483.6375 NAC DEF
(RI) Pawtucket PD 1 470.725 NAC 293
(RI) Pawtucket PD 2 471.075 NAC 293

I dont understand how to get any further. attached is the GROUP PARAMETER, which I dont understand. I dont use any alert tones or sounds. When I try to set the "TGID group list, I get error saying both Cranston and Pawtucket, since they each both have the same "NAC" it says they each both have the have the same TGID's???? I only can enter the NAC.....there are no talk groups I can see for these users. So until I can get past this point I am stuck!

You don't set up new protocols, all of them use the P25 Conventional protocol. You program them in the zone/knob position you want (one freq per knob). If you don't know TGs use the monitor setting with 65535 wildcard, set up in E-6.1 and E-6.2.

I am still not understanding, sorry. Did I do this right? I click on each entry in the E-6.1 and make the TGID wildcard. But when I try to go further I get this error. I remember this problem before but can't remember how to fix. And I keep getting error complaining that all entries have the same TG. I go to "Conventional group ID settings" and get this error, error2 in picture. So I am going around in circles.

You list the wildcard 65535 ONE TIME in E-6.1, you then go to E-6.2 and create ONE group, call it "conventional" "wildcard" whatever u want and that is what you use as the TGID Grouping List current setting. This same one would be used for all entries, you do not need separate ones for each group if you are only using 65535.

OK I think I got it right but I cant get to the place where you add the freqs to the scan list for a knob position. I want to assign these 5 P25 conv. channels all into zone 1 knob 5. Is it because they are all set to "Monitor"? OK Changed to normal scan and I think it is working.

 

[bobruzzo]

I see under "Receive voice call" "To" and "Fm".......I guess thats "to" and "from" dispatcher and patrol. These numbers change so how would you find the actual talk groups on a conventional P25 setup? Are these numbers some kind of radio ID or officers radio ID number? I guess it doesnt really matter, cause you can still see who the call is from. But it seems with wildcards, the background colors dont work. I set them all to "blue".

With a group call, the from is radio ID and the to is the talkgroup.

Not sure how private calls would look, perhaps both are radio IDs…

Normal scan would be correct. Once you pick that you can select which channels to scan.

OK I am saving this thread for future use. Any idea why the background color doesnt display? I have it set in the PPS. Its set for these 5 channels.

I apologize I haven't really set up any background colors, maybe that will be my next thing I mess with on these things. I'm still working on trying to get a couple of my spectrum scan positions working a little better and my MOSWIN (Missouri) stuff working a little better that uses both 700/800 and VHF. I guess next will be the colors maybe. Sorry I cannot help there.

I’m still learning the G5 and the PPS myself but as @jtwalker posted, the “To:” is the TALKGROUP number.

I don’t know what the longer “From:” number represents or if that is listed somewhere to reference.

When I’m monitoring at my computer, I have the RR page open to the Massachusetts CoMIRS system and do a browser search when a particular TAlKGROUP number in DEC format displays to see who it is. If I’m interested, I may program that in.

At the moment my wife does the driving and when we're mobile and not in the areas around home, I have the wild card set up to receive everything and I'll look up the TG numbers as they pop up, if it's not obvious by the traffic what they are.

the actual user ID of the transmitting unit. "usually" 'these are grouped closely by number by the various departments. At times I only see "From P-25" in that line so not sure what that's all about. Guess the pager either isn't decoding the UID or radio isn't sending one.

For some reason, when wildcard is set, even tho background color is set in PPS, it still won't display. Maybe its because a talk group number must have to be present? I am wondering instead of using "Normal scan" instead use "Free scan" in the Zone and channel settings.....Still working out minor things in the G5......great radio. The main thing is, in a trunked P25 system, the talk groups are plainly available like in the RR database. But for stand alone, when you look at radio screen when theres a transmission, the numbers keep changing so its hard to find the actual TG for the freq being monitored.

OK if the "To" is talkgroup number I will keep a record when transmission occur, but if there are more than 1 instance of a talkgroup number it wont work. I noticed a number "1" so I will keep an eye out. I am monitoring 5 standalone conv P25 channels so hopefully they will all have different TG numbers!
