I noticed a small BUG when I'm using SINGLE mode.

If the option: "Create Call Activity CVS - NO CALLS" is checked, the TTT window starts to display information. Even if "Suppres Lockout Messages" is enabled.
The Tbm drop-down window (F12) displays gray information.

In dual mode these things do not occur. If you have a way, I thank you! ;)
That's not a bug, it's a limitation of TTT in single mode.
To create that file TTT must be always on MCCH.
The 'Call details' panel and remote window will show these set-ups (grayed out) because they are calls that are on a different carrier.
Calls that are on same carrier as MCCH should play as normal.
Suppress lockout messages won't apply here as this mode "Create Call Activity CVS - NO CALLS" is about logging all setups.
This limitation does not affect dual mode.

It's in 21.4.4.1 SYSINFO (page 697) of EN300-392-02 V3.8.1

page 698 said:
The hyperframe/cipher key flag shall indicate whether the following information element is the hyperframe number
information element or the CCK identifier or static cipher key version number information element. The usage of the
CCK identifier or static cipher key version number information element is defined in ETSI EN 300 392-7 [8].

Thanks for sharing but the documents describes the "Hyperframe_or_Cipher_key_flag"

I was asking about the "Cipher_key" under "Advanced_link_supported" and the representation of the value.

I am trying to analyze the security of the network
-what security class it uses?
- is OTAR used?
and to know more about TETRA systems

I did quote and added bold to the document with more information on the subject.

[QUOTE = "thewraith2008, post: 3066039, membro: 1029543"] Non riesco a scaricare quel file perché vuole una "chiave di decrittazione"
È necessario modificare la modalità di condivisione o inviarmi la "chiave di decrittazione" solo tramite PM. [/CITAZIONE]

I am using hackRF one and the program crash after some time.
I'll try to post the debug info when this happens again
I put a heavy cooler fan on RTLSDR keep it ice cold, Heating seem Not the problem in my case because still suffer from crashes after some time
I role back to early version TTT and try locate in what version the crash started.
