True P25 works in two ways Explicit and Implicit If it is Explicit you could possibly use a CC to decode the freqs However CC DO NOT WORK if it is Implicit you MUST have the Band plan and freq and the correct step to tell the scanner witch channel to go to. It is diffrent than standerd P25 voice like Safe T. And yes it will help the transition to Digital.

I'm saying two things. One wait until the Control Channels show up on the "new" frequncies, then you will be able to figure out which one goes to system 1 & 2. Then put Trunker on it and it should/will tell you all the active frequncies for that system. It's easier than guessing or speculating.

The second thing is, I'm saying/guessing they need a mix of the old frequncies and the new for transition to the new and rebanded system.
Unless they have enough techs that can fan out to all the sites that use radios and switch them over from the old to the new. (Ithink it is going to be a several day process)
Usually what happens is the new and old are programmed, when everybody and everything has been switched over, they go back and switch out the old frequncies.

I have never needed to worry about implicit or explicit when monitoring a true APCO 25 system, and I don't think I'll need to start with MECA.

MECA is making changes on system 2 right now if any one wants to listen regular old ANALOG no longer trunks right now. CC sounds like true P25 or a realy messed up type 2 with errors and tunning it in.

Looks like sys 2 has trouble and is affecting mostly areas north of 42nd street down town seems to be running ok the other channles are up and running and there is plenty of analog traffic on there. They are working on it.

boy oh Boy you just dont get it thats ok !

Don't get what... Just an optional suggestion, wait until the control channel changes, and then figure out what frequncies go with what system. I think thats a splendid idea.

It's Just a suggestion instead of posting frequncies, then saying that wrong, of you don't know which goes to which system. Why not just wait until they begin with the new Control Channels.

And the Explicit and Implicit I don't understand what you mean by that? I monitor three APCO 25 systems, none of them need any table information entered manually, and all three track fine without it. I believe MECA will be the same way.

Like I said you dont get it! If you have a 996t or a 396 T look in the book it will teach you somthing I am not your teacher sorry. True P25 is diffrent than p25 voice like Safe T and there is NO true P25 system online in Indiana. Go read and learn. That's all I have to say to you since you like to stirr the pot in every post you do.

No need to be hostile. Correct, there are no P25 systems in your neck of the woods.

But I can monitor P25 systems operating in Kentucky from Indiana. And I do know the difference. Those living on the Illinois border also can hear P25 systems in Indiana. And don’t forget the ones living close to Michigan. And there may be one system operating at Crane Naval support.

I don’t get what you mean by implicit or explicit system. That should have no bearing on MECA whatsoever. Plus the advantage of P25 is that it can also co-exist with Smartzone/Smartnet 3600 baud systems.

I did ask for you to teach me, as I still learning and do not have my brains shut to other possibilities like you appear to do whenever you hear something you don’t agree with. Tell what you mean about the implicit and explicit.

Most likely, they will use the new frequencies, and the old frequencies until all the radios are programmed and operating normally. Until then, there will be a mix of frequencies in use and testing. All you have to do is program the Control Channels and I know my BCD396 will track the system just fine like it tracks the other 9600 baud systems that I monitor. It appears you are the one confused. However there is no need for nastiness or ad hominem attacks.

After doing some checking MECA can use Digital under the Emission 20K0F3E and 15K0F2D
for WNNM854 SYS 1 and SYS 2

15K0F2D I believe that would be the Motorola MOSCAD data, and the other would be FM narrowband voice.

The IndyGo buses have new Motorola radios. I haven't been able to get the model # yet.

Crane hasn't installed the new system yet, it was just approved not long ago.

If any one else can pick this up you may want to try

New CC on MECA 858.1875 Very low power
MOTO SYS
Site ID 0262H-0101



996T Trunking on TRUE P25 9600 858.1875 Very low power
Same ID

Does NOT work on Standard moto 800 Digital only true P25

Receiving it here also, the best decode rate I have seen is 98%. Will check it out in Unitrunker.

No luck here with UniTrunker signal is to weak working on a preamp to see if i can bring it in better

Awesome guys, keep us updated and I will update the DB. I have created 2 new systems. I imagine this is system 2.

Unitrunker Screen Shots

A few screen shots from Unitrunker. I actually decoded this system at 100% at one point using just the tapped PRO-93 with the RS 800 antenna, and I am located about 3 miles south of the Marion County line.
