What is I in T field in unitrunker

[ronenp]

Hi there
What is the I in the T field ?
There is a radio id in the target field but no radio id in the source field

 

[SRSP2282]

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.

So why i dont see at least the source radio id and the target radio id
after all radio id 1 is tallking to radio id 2 so both id should be seen a thing that is not happening .

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.

I get 100 % reception (the software say health 100)
The CC is strong and no noise
I dont miss ant regular TG i always see both source and TG
but when it come to Private calles it only show the target id

 

[SCPD]

Interesting. What system is this?

 

[ronenp]

It is smartzone Trunked P25 Type I (digital )

 

[SCPD]

Very weird. Please send a decode log.

There's no such thing as a P25 SmartZone Type I system.

What's the system ID?

 

[ronenp]

I ment for type I Phase I (not the X2 TDMA)

 

[SCPD]

I assumed he meant Motorola Type 2 with P25 voice.

 

[ronenp]

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 also see an I on Dat (data) calls. I assumed it meant individual.

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?

 

[ronenp]

Yes
I see Dat in the SVC
