From the Radio Reference Wiki: Column "T" = "Type" which would be [G]roup or individual (iCall)
UniTrunker - The RadioReference Wiki

In other words a "private" call between two individual radios.

There is a radio id in the target field but no radio id in the source field
Not sure what to make of that... Unitrunker shows both radio IDs when monitoring I-Calls on my Motorola Type II SmartZone system.

Hi Ronen;

You asked a similar question a long time ago.

If the decode rate is low, you will miss the channel grant - which has both source and target IDs. The late entry messages carry only the target ID.

P25 Digital trunking

I went to the WIKI to see what is written there that the description i write will be understandable
so it is a Digital Trunking p25 Phase 1 with 9600 Baud Control Channel ....
Hope now it is more clear

I've got a log file for this system. Definitely P25. I did not see any Unit to Unit calls in the log example. However, the system is capable of SNDCP data calls. Ronen, do you see "Dat" under the SVC column on these calls?
