I am trying to figure out SmartNet control channel messages. To do this I have been looking at the decoder logs from UniTrunker. I am confused though. Does Unitrunker put all of the control channel messages in the log?
I am confused on the messages that make up a Grant. I thought the Grant sequence had to start with a 0x308, 0x320, or 0x321 command, followed by a message with the source and then finally a message with the talkgroup and frequency.
Unitrunker seems to be pulling Grants out of very different sequences:
8209 G 12A
2AA6 G 30B Net ID=8209, DChan=2A6 0.0000
5F5E I 12D
87D0 G 2A9 Channel Grant Astro 2A9 I 5F5E -> G 87D0
82A1 I 049
88B0 G 1C5 Channel Grant Astro 1C5 I 82A1 -> G 88B0
5F5E I 12D
87D0 G 2A9 Channel Grant Astro 2A9 I 5F5E -> G 87D0
4B40 G 3C0 System Status [2] = 0B40
5F5E I 12D
87D0 G 2A9 Channel Grant Astro 2A9 I 5F5E -> G 87D0
0000 G 360 Site 1
5F5E I 12D
87D0 G 2A9 Channel Grant Astro 2A9 I 5F5E -> G 87D0
Is it simply that a 0x3-- message can put it into a mode where Grant sequences can start and any number of Grants can be stacked together?
Any pointers on the different possible SmartNet message sequence that could make up a Grant?
