Not quite true, its only basic privacy and is very easy to decode in real time.
Please tell everyone what you would use to decode encrypted tg's that would be easy to use. and remember it's unlawful to do it.

If it's "very easy" then I'm sure you can explain how to do it...?
The easiest thing would be using a HackRF to inject code that mimics over the air program to turn a single radio in the talkgroup into clear mode. Once that happens the whole talk group becomes unecrypted. You might not be able to crack the encryption but there are ways to disable it. (This is for education purposed only do not try at home)
Why complicate it?
There are 255 BP keys.
You can determine the key number by looking at the AMBE frames.
Once you have determined the key number, XOR each AMBE voice frame with that BP key.
I'm more talking about NXDN and P25 where AES and DES are used. If you cant crack the encryption you have to do a front end exploit. remember we are just talking about this for education purposes and not condoning listening in a public safety organization that feels it needs to hide it's basic dispatch. "You have nothing to fear if you have nothing to hide"- a police officer that said that when I was a kid
Buy a TRBO radio. Try each BP key one at a time. Celebrate.

Oh... and I just noticed from the screenshot in the original post that RAS is being used too. So even with the correct BP key you will be out of luck.
