Joseph Cardani jcardani@verizon.net [op25-dev] op25-dev at yahoogroups.comStill making progress on the mods. Great news, I now figured out the LDU1 frame and can display the TGID and RID from lco = 0. I just needed more detail on the CAI protocol than what I previously had. I am cleaning up the code a bit and will post the latest when done. The output below is from a voice channel. Motorola P25 Phase I system. Algo ID/KID 0/MI zeros = non encrypted transmission. TGID 161 and RID 7028138. This is from a subscriber unit (not a console) based on the RID Notice the silence voice frames transmitted in the first LDU1, directly after the HDU. They are 04 0C FD etc…. And only LDU1 with an lco = 0 carries the TGID and RID. Finally it appears that the TDU always shows a RID of 0 but the TGID does match the one in the HDU.
