If any Department switches Digital programs from Phase 1 to a Phase 2 does that mean the program goes to the TDMA ?

Rather listen than to stream
Yes, and if your scanner is only phase 1 capable you won’t be able to listen.
I'm not sure exactly what you are trying to determine. Is this in reference to a specific scanner, and/or regarding one of the scanner programming software packages?
Programming for a system is the same whether they are using P25 Phase I or Phase II. There is no difference in the way talkgroups are entered, nor the way sites are set up.
If a system that was P25 Phase I when you first set it up, but then switches to using Phase II talkgroups, you do not need to adjust your talkgroups & sites settings. Of course, if you are using a scanner only capable of receiving P25 Phase I, then you would lose the ability to monitor any talkgroup that transitions to using Phase II, but still could listen to any that remained Phase I.
Looking at your county (Leavenworth) in the database, there are some conventional (non-trunked) channels, but it appears that most of the public safety agencies are using the statewide KSICS system. It is labeled in the database as P25 Phase II, because the system is capable of using that mode.
However, at present, the listed talkgroups for your county are shown as P25 Phase I, as designated by the D in the mode column.
If, at some point, one or more of the agencies switch to P25 Phase II (and that change is submitted to the database), then any TGIDs that changed to P25 Phase II would show a T in the mode column. The T references that Phase II is used. But as long as the scanner you are using is capable of receiving Phase II radio traffic, you would not need to edit your programming except for any new talkgroups being added. If any specific talkgroup changes it's TGID, or new ones are added, you would, of course, need to account for that. Of the systems that I monitor here in the DFW Metro area, some systems (or one of their agencies) have moved partially, or fully, from Phase I to Phase II. But they did not change their actual TGIDs, so no need to edit them.
If i am reading your post right that IF my County goes to Phase 2 it should be a TDMA & IF anyone puts a posting of the change to phase 2 to R&R & IF no one post a change in the program system to R&R then every one thinks it is still a Phase 1 program, is this correct ?
It seems you may be "overthinking" this.
Your county, Leavenworth, KS, uses the statewide KSICS system. If you look at it in the database, it shows as being "Project 25 Phase II".
As noted above, that means that it is capable of using Phase II communications. However, unless I overlooked one in a quick skim through the talkgroups, it appears that, at present, all of the talkgroups (not just your county) are still using P25 Phase I, as denoted by the D in the mode column.
If your county, or one of the others, moves to using Phase II, that does not mean that you have to update your programming. While someone could add a few more TGIDs, or add a frequency to one of the sites due to the amount of traffic, no change would have to be made for your area in the existing talkgroups. As long as the scanner you are using is capable of handling P25 Phase II talkgroups, then no changes are needed. If you were using one of the older scanners, such as one of the GRE/Whistler models (PSR500, PSR600, Pro 106, Pro 197, Pro 651, Pro 652, WS104, WS1065), then you're out of luck, since those are not capable of handling Phase II.
Looking at some of your older posts, it looks like you may have a WS1040. So, yes, if your area, or at least an agency that you want to monitor, upgrades to using P25 Phase II, then you would no longer be able to monitor those Phase II transmissions. Those scanners do not have the internal hardware needed to handle Phase II, and they cannot be upgraded. Neither does Uniden's 396XT or 996XT, or the HP-1.
For a scanner such as Uniden's 436HP, which can handle Phase II, look at your programming options:
You see a P25 Trunk system. Nowhere does it say 'Phase I' or 'Phase II'. You either set up a P25 system, or not monitor the system. There is zero difference in the way in the way it is programmed when using Phase I or Phase II. (Ignore the P25 X2-TDMA. That was the initial format used for Phase II, but it is no longer used.)
Thank you very much Sir !
