On the BCD396XT / system types = confused

• Motorola Type II
• Project 25 Standard Phase I (not Phase II) / what is the difference between the two ?

Motorola Type 2 is an older system format that has passed its end of life. There's some still online but mostly migrating to P25. There are a couple different variations of it. Later ones allowed a mix of P25 and analog voice on the system. The control channels are analog.

P25 systems are an entirely digital format. Control channels and voice are digital. You can read more about it off the Wiki.

Motorola Type II is an older type of trunked system. P25 is a newer upgraded type of system with more features. There are P25 Phase 1 and Phase 2 systems. The first P25 systems were Phase 1 had only one audio channel per frequency. P25 Phase 2 systems are TDMA (Time Division Multiple Access) with 2 audio channels (slots) per frequency. Phase 2 systems allow more radio traffic on a system using the same number of frequencies as a Phase 1 system. Motorola Type II systems require a custom band plan for sites with rebanded 800 MHz frequencies as well as sites with VHF and UHF frequencies. P25 systems load the band plan automatically from the control channel. The BCD396XT is capable of P25 Phase 1 only. The KSICS trunked system is P25 Phase 2 capable. The database shows all talkgroups are currently Phase 1 (D in Mode column) which your scanner can receive. Any talkgroups with T (TDMA) in the Mode column are Phase 2 which the BCD396XT cannot decode. DE and TE talkgroups are fully encrypted and cannot be received by any scanner. De and Te talkgroups are encrypted part of the time.

One major difference between the two is Type-II can have analog or digital voicing. Phase-II never has analog voicing.

Thanks for the info !
