Hi All,
Here are my code changes attached. Most are in software_imbe_decoder.cc and rs.cc
I tried to document the best I can, my initials are next to my changes.
Again I am gonna need some help with retrieving the RID (source) and other fields from the LDU1 and TDU with LC frames.
thanks!

Hi Matt,
Sure no problem. The code is not elegant, so if anyone has a more efficient way of handling things I’m all ears.And again any help with the coding to retrieve the RID and other stuff from the LDU1 and TDU would be greatly appreciated.
I’ll post tomorrow after I clean up some stuff. Getting late here.
thanks!
Joe

Hey Joe,
Can you post your code here so that anyone that's interested may have a look?
Cheers,
Matt

Also for those who are interested, I was finally successful with displaying the voice frames in OP25. Made the appropriate code changes and now VC1 through VC9 displays after each LDU1 or LDU2 frame. 11 bytes of VC info are displayed. For example an unencrypted silence frame from a subscriber unit for VC1 and VC2 appear like
VC1 is 04 0C FD 7B FB 7D F2 7B 3D 9E 44 VC2 is 04 0C FD 7B FB 7D F2 7B 3D 9E 45
Also found an issue with the MI that’s displayed in the LDU2. It’s displayed by OP25 as 12 hex bytes. I re-formatted it to display as 9 regular bytes, with the first 8 having relevant information. I also added a display of the MI that’s in the HDR.
I’m starting on coding to display the TGID and RID (Destination and Source) that’s located in the LDU1 and TDU, but the error coding appears not to have been done here. That is way over my head so can anyone be kind enough to help with this?
Once I test my code changes I’ll submit them to Max or anyone else who can incorporate them into the OP25 release. Testing this code is the reason I inquired on how to record a P25 voice channel so a friend can record and send me test files that I can play it back in OP25.
Here is the sample output from the console:
