T instead of E?

[mass-man]

Looking thru the Bell County, TX listings this morning and noticed while the majority of the system is D, in a couple of instances it shows T. But on TGs that usually are E on other systems, such as TAC and SWAT. Is there an advantage to T over E? I read there are a few instances of E being used sporadically, so its available...just wonderin?????

T indicates a phase 2 talkgroup, D a phase 1 talkgroup. If you hover your mouse over column heading, there should be a text blurb about the column.

Yes: "T" (with no "E") is "in the clear". "E" (as in DE & TE) indicates full encryption: CAN NOT BE MONITORED.
in a nutshell the "T" is advantageous to the scanner listener while the "E" can be seen as "advantageous" to the agency concealing their comms from the public

How can you tell the difference between a Phase I TG, and a Phase II TG?

Most software designed to track/decode P25 will have some sort of indication as to whether a talkgroup is FDMA or TDMA. Most newer Uniden scanners will also indicate the mode.
