1. P25 Phase 1 (C4FM) is one transmission per channel. P25 Phase II is two-slot TDMA which gives two voice paths per channel.
2. I¡¯d suggest starting with the Wiki which, although it¡¯s geared more to scanner users, does have some decent info on P25. There are some white papers out there elsewhere which go more deeply into the theory behind P25 but I can¡¯t remember where offhand.
3. Yes, you could patch a P25 repeater to an analog repeater, although you need to be careful about where you get the audio. Best bet is probably to use wireline connections so the audio is analog.

1a. Re: Voice ID'er for P25 Repeater???Posted by: "Ed McKinney"?kb8qeu@...?kbhz5746???Date: Wed Sep 12, 2018 4:41 pm ((PDT))HiI am interested in the VHF (2 meter ham) P-25.I read where they are 4TDM or something like that where four can have fourconversations at once without interference with each, similar to trunking.Am I thinking right?For the whole group about P-25, is there a website I can go-to to learnP-25 deeply? Or, any PDF for downloading?I really had not learned much digital for in my past in the late 70s, theywere talking about such in the W3C magazine. I use to read it at TexasInstrument's library.I do want to have a P-25 at my repeater stack of analogs.Also, can a P-25 be tied/linked with the analogs via an audio bridge?
