I have been watching a local Motorola UHF Type II system for a while and have a question about the results I am seeing logged in the Usage_hex field of the Groups file. The system I am watching has several analog and several encrypted talkgroups, and I have also seen emergency calls. In looking at the Usage_hex field of the group file, I find that there are 5 different values that have been recorded for the talkgroups. They are 0, 2, 8, 9, and a.
I reviewed the trunker documentation, and 3 past posts in the trunker mail list on this topic, and I believe that the list below represents the 5 type of conversations that have occurred for these talkgroups:
0 = analog
2 = DES encrypted
8 = encrypted Astro or other digital
9 = (encrypted Astro or other digital)+(emergency)
a = (encrypted Astro or other digital)+(DES encrypted)
Could someone comment if this looks correct and I am interpreting the documentation correctly?
It would appear to me that this list would be all the possibilities for a Motorola system. Does this look correct?
0 = analog
1 = emergency
2 = DES encrypted
3 = (DES encrypted)+(emergency)
4 = Astro or other digital
5 = (Astro or other digital)+(emergency)
6 = (Astro or other digital)+(DES encrypted)
7 = (Astro or other digital)+(emergency)+(DES encrypted)
8 = encrypted Astro or other digital
9 = (encrypted Astro or other digital)+(emergency)
a = (encrypted Astro or other digital)+(DES encrypted)
b = (encrypted Astro or other digital)+(emergency)+(DES encrypted) c = (encrypted Astro or other digital)+(astro or other digital)
Many thanks for the help!
