Ok, I'm a newbie with a pro-96... I know dangerous.


The problem is that when I go to program in the control channels for the Atlanta and North Fulton TRS, the pro-96 starts asking me questions that make me think the Internet is clueless. You see it asks for things like "offsets" and "steps" But nowhere on the internet can I find this detailed info. It's almost as if it's something I should already know... but I don't.

Now, I can probably figure that the offset is the part after the decimal in a frequency. But then I think.. "That's stupid, why wouldnt you just type the whole thing into the tuner? Why do you need an offset?" I Understand what the steps are, but can't seem to find them listed anywhere on any atlanta site.

Then to top it off, I get directed, by the local police to scanatlanta.com which doesn't even have any [edit: CURRENT frequencies] listed.. it just provides feeds of police scanner data. Any freq's that are listed are fromthe old type IIi hybrid system. Their freqs haven't been updated since 2006.

I'm so frustrated! Please help.

if you look closely on scanatalanta.com you will see a link that says "FREQUENCIES" click on that, then click on Troop C, then click the link that says Atlanta TRS.





ahhh what the hell, here



http://www.scanatlanta.com/AtlantaTRS.htm



Yep, but here is the problem. That states it is a Type IIi Hybrid and hasn't been updated since 2006. From what Radioreference.com says at http://www.radioreference.com/apps/db/?sid=1580 Fulton was updated to a full Type II and the radiorefernce page was updated May of 2007.

They both show different frequencies.. Yet the radio reference one doesn't seem to be complete either given the control channels I'm finding.

So once again, it would be much easier to just type this in using the pure Motorolla Trunk setup witha Base freq, an offset and a step. Can anyone tell me what those are?

If not.. then why are those even asked for during the Motorolla setup on the pro-96? Keep in mind, I am looking for SPECIFICS of the TRS System. What I am finding are really good guidelines, but nothing specific and up-to-date.

The four CC's are in red for Fulton County. How are you programming the scanner. I use Win96 for mine. Have had it for almost three years now. No problems scanning the Fulton county system, or Atlanta when I am in range. Atlanta has four CC's also that are separate from Fulton's. The two systems should be programmed into two separate banks. If you are programming by hand, remember to make sure the bank is in MOT mode, then when programming the frequencies in, make sure they are in MOT mode. You are not being very specific what the problem is. What is in radio reference is the most up to date info. No base, offsets, or steps need to be programmed in. Just the CC's.

Thanks Larry. I think the disconnect on my end, is that I know how to make a channel MOT, but I don't know how to make a BANK MOT. Now, when I follow the tutorial of saving a TRUNK to a BANK, it asks me for things like "Base Freq, Offset, and Step" Which I don't have. I would prefer to program (manual) it the way it should be done so I don't have to know the control channels, (as they change all the time), and can give it the base with the steps so it can work it's magic.

If I can't do this, do you have a reason as to why the control channels change so often? That is my biggest issue. Once I get all the stuff in Red typed in, and it turns to midnight, or some other time change, then it basically stops scanning, because those which used to be control channels stop being control channels.

Yeah, I know about that! I sold the site to the owner of ScanAmerica.us and it hasn't been updated in a while. It is in some serious updating, but the info there is pretty valid.

Blue0ne - welcome to the site! PLEASE don't be afraid to ask for any help here as we were all "dangerous" in the beginning!

Thank you very much for the welcome! I can totally understand what happened.

I'll tell you what I did. I programmed in every freq on the radiorefernce page and set them all MOT. That "seems" to be working currently. I'm still uber curious as to what the actual Programming trunk details are, such as base freq, offset, and step for the Fulton TRS (Yeah I was actually after fulton).

You don't happen to have an idea as to what Talk ID's the new Johns Creek is using do ya?

First, /\/\ike and I are both still dangerous :))
Second, To program a bank in MOT mode: (page 33 of the manual) press PGM, then FUNC, then the up/down arrows to get to the bank that you wish to program. Press TRUNK to access the ID list. Press the MODE button until MOT appears. Press PGM to return to the channel storage bank. Program the frequency and press ENTER. Press MODE to change the receive frequency to MOT. Continue until all have been programmed. Keep the book open when doing this. I like to use sticky notes to get me to the different pages quickly.
Third, we all would like to know what the TGID for Johns Creek is! Listen on different SO and PD TG's and let us know when you find it.
My biggest complaint going is that Gwinnett's new P-25 system is ENCRYPTED. BAH on Gwinnett!

You only need to enter the control channels. Even if they do roll the control channels, you have them programmed in and it won't matter. Gwinnett does it all the time on their analog system.

Just for clarification, the base frequency, offset, and step are used mainly on vhf/uhf trunked systems. There are a few exceptions for 800Mhz. One example is a new P-25 system in the area I used to call home. One has to program the neccessary frequency, offset and step to get the system to scan.

Thanks!

Hey, I'd like to thank ya both for the assistance. I feel as if I've got everything working where it should just now. Although, I think it's odd that I'm not hearing any Johns Creek transmissions just yet. Unless they are piggybacking on other TalkGroupID's.

I called the Public Affairs officer and had asked for control channels the other day, and she got back to me that they are using the Fulton Trunk Radio System. This is because most of the Officers volunteered from the Fulton County force.

I just sent her an email today asking for TGID's... Don't know how far I'll get, but I'll let ya know.

I often see the troopers in Outback in the evenings, so the next time I do, I might just drop a Signal 89 and ask them straight up.


Oh, and Thanks Much! for the description of the types of systems that need the Base, Offset, and Step! That cleared things up a lot for me. Much appreciated.

I must say, this pro-96 is the best toy I've bought in a long time.

If you want to listen to what P-25 digital sounds like, program Cobb, and Forsyth into the scanner. They are programmed in MOT mode and will change to digital when it decodes the signal. MARTA is digital and analog. Sometimes interesting listening.

So here is the reply I got from the Public Affairs Officer of Johns Creek. She has been very helpful thus far, even if the information has been limited.

<response from JCPOA>
As our 911 service is controlled by the Fulton County 911 Center, I'd suggest you try to obtain the information you're looking for from them. We are just renting space on their radio system. We operate on what used to be called Fulton County North Patrol. If you still have those talk group ID&#8217;s they are the same ones the Johns Creek Police Dept. is currently using.

Ok now I have another couple questions.


On this page http://www.radioreference.com/apps/db/?sid=1580 there is a list of TalkGroupID's for Fulton County. However, there is also, in the same tables, Sub-Fleet numbers. How can I use these?



Also, I've recently typed in everyone of the control freqs listed on radiorefernce for Atlanta Public Safety, and I'm getting no control channels up. Any ideas?

Program up the FULCO site as Type II. I believe everyone has moved over from Type I (the sub-fleet id's).

46384 is the old FCPD North channel, so that is where you will find Johns Creek. I would venture to guess that you might find Milton up on one of the old FCPD North TAC channels.

Thumbs up to you for contacting them directly! GSP you will find are working off of the Atlanta system. They do have a TG on the Cobb P25, but I've never heard a peep up there.

Guess you live in Johns Creek area?

Yep I'm a recent Move-in from last year. Came up from perimeter.


Man I tell you what, Once you get the signals and codes down for Fulton, bringing Atlanta into the mix is a whole other ballgame.

Fulton county is operating as a Type II system. The subfleet codes have gotten Type II TGID's. What Atlanta frequencies are you programming? There should be 4: 856.4625, 858.4625, 858.7625, 859.2375.

I had sent a copy of the latest APD signals/codes to ScanFulton, but they haven't made it up there. I'll upload a copy of them to RR.

Johns Creek Tactical

By luck tonight I happened to here something goin on in Johns Creek, and they swithced to Tac. I immediately toggled pause on the ID, and up popped the rest of the convo on talk ID 46928. It's not listed in the Fulton County Codes, but should be.


How do we get the Johns creek ID's listed in there? We need to change North Fulton Main to Johns Creek PD and add 46928 as TAC (at this point I'm Guessin TAC1 is all they have)
