Rather than point in a 14 page thread (in a PM), why don't you ask a specific question?:roll:

What "fact" did you state?

Here is the thread he referred to

There are 20 posts on that page!
I must have missed it?:roll:

There's several RFP's out there for new systems already stipulating Phase 2 "compliance" and/or "compatibility" but most of them, if not all, will be Phase 1, at least initally. One way or another and as far as I know, Phase 2 systems will be backwards compatible with Phase 1, so as to make a slow and easy migration path and so on. I've even "heard" the control channel format/baud rate will stay the same as it is currently. It's too early for anything to be "set in stone" about Phase 2. The committee have finally decided in using TDMA in just the past 6 months....

There is quite a lot that, while not set in stone, all bets are will not change.
There are still things to be ironed out.
There are no systems, nor equipment out there yet.
It will be TDMA 2:1
It will have a 9600 BPS control channel, similar to and compatible with the current control channel. (Basically the existing control channel with added messages)
It will be 12 KBPS on the voice channels (6000 BPS per slot).
It will be Enhanced AMBE 1/2 rate vocoder (somewhat compatible with full rate IMBE).

Those DVSI guys sure did hit gold didn't they?
It would have been nice if they could/would have been able to use something open sourced.

My mistake, you did not PM me, someone else PMed me pointing out your insistence in the same ERRONEOUS "fact" (as you like to call it).
Repeating it will not make it any more accurate.
There is NO P25 Phase 2 out there yet!
Soon, but not yet, and the first systems will be Motorola's "pre-Phase 2" (for lack of a better term) 9600 BPS TDMA systems.

How much do you want to bet?:twisted:
EDIT:
Why don't you define what you mean by Phase 2, since we are obviously speaking a different language.
I sand behind the statement I have made as they pertain to Project 25 Phase 2 TDMA.

So you're going off that one conversation with that bigwig thinking that you or he knew exactly or understood properly what they were talking about? You sure he didn't mean the equipment would just be compliant? As of right now you CANNOT purchase anything that will operate in Phase II mode. What's out there is only compliant. If you seem to know differently you need to provide the facts stating so.Viper43 said:Once again you do not have a clue, if you did, you'd know there IS equipment out there and that Motorola has tested it and it will soon be installed
Judging by that thread I doubt there's anything that will convince you that you are misunderstanding the situation. I'll be pitching in to N_Jay's pot in that you are not correct.

It would be helpful, if you would tell us some specifics:
1. Who will own the new system(s)
2. Where it will be installed (state / county / city / town)
3. When it will be operational

Really?
No answer yet to EXACTLY where I am wrong?
Maybe this link will help you.

There are "Want-to-be"s and there are "Know-it-all"s, but you take the cake as a "Want-to-be"-"Know-it-all"!:twisted: :lol: :twisted:
