What is exactly is P25 on the Amateur Bands?

[KN4HTC]

I see some repeaters listed a P25 capable. How exactly does P25 work when it comes to Amateur radio?

Is is basically just a conventional repeater the uses the P25 codec?

What exactly separates it from DMR? Are there multiple talkgroups available like with DMR?

A lot of it has been discussed in this thread:
Digital Trunking (DMR Tier 3, P25, NXDN) on Amateur Bands?

In reality yes. I run a P25 repeater. I have no talkgroups assigned in mine. Others link to P25NX and have multiple talkgroups available.

We have a repeater here that's running an MMDVM, run our own server so we can create dedicated stand-alone and linked talk groups.
Most of us (probably all of us) running P25 are operating with second hand Motorola/Kenwood or other Commerical/Public Safety radios in the amateur bands using conventional P25 Digital.

Trunking can be had however trying to find the bandwidth to pull that off in an amateur allocation isn't likely easy... I've never seen one setup in trunking on the ham bands.

Around here it means setting up a P25 Quantar repeater. The users would then use a P25 radio to communicate with other users. So Astro Sabers, XTS3000’s, 5000’s, 2500’s, or even APX’s would be used. No talk groups, no internet connections, or anything like DMR. Analog, or P25. This is what we do in S. Florida. I don’t know what they do elsewhere.

Same here in central California, but some P25 repeater systems are linked via Internet or RF giving us wide coverage.
