I am looking for sounds of Motorola MTP850 and the likes to use with TTT (i.e. replace the standard call setup, release, priority, etc in the snd-folder). I know there are some recording on Youtube, but I haven't found anyone without too much background noise.

If someone has files ready, or know the tone frequencies / lengths it would make my day :)

Hi everyone. I have a question. I use 1 usb dongle and a single mode of TTT. I accept channel 1001 (Main:1001 Current:1001) and channel 1009 (Main:1001 Current:1009). TTT is located on channel 1001. How do I make TTT jump from 1001 to 1009 if the call is 1009???

That's what TTT are used for, it does it for you, trunk tracking the call. If you do not use trunk tracking you only have to use the russian tetra plugin.

If a call to 1009 SDRSharp + TTT does NOT automatically switch to channel 1009. How can I fix this?

The best way to start would be to read the documentation and ensure that you have followed it. It has to be something you have missed.

I use a translator. It is very difficult for me to understand what is written in the instructions.

Hi all.
I'm trying to install last version ( 1.7.1.0 ) but windows block it by Trojan:Win32/Azden.B!cl.

Have you notice that? Any version clean or other links avaliabe?

Thanks,

You are using the TETRA Demodulator plug-in + TTT in single mode, How are you determining that there is a call on carrier: 1009?
Does this show up in the 'Network Info' window on the Calls tab?
What kind of call is it? Group/Private. Do you have any logs of the call setups?
Does TTT follow other calls? (on carrier 1001)
It's possible that the activity on 1009 is not for a call that was setup on the current LA. TTT does not work with this kind of scenario.
It's possible that the call is encrypted in which case there will not be any call following.



Latest version (v1.7.1.0) can be found here: Release post

Yes. I use 1 USB dongle + TTT in single mode.

Yes. Displays activity on the Main channel + Other channels belonging to the main channel.
What kind of call is it? Group/Private. Do you have any logs of the call setups?
Yes. I still have the logs.
Does TTT follow other calls? (on carrier 1001)
TTТ displays all 1001M + 1009 activity. Sharp is located at 1001M and plays 1001M calls. BUT DOES not JUMP to 1009 when calling there.
It's possible that the activity on 1009 is not for a call that was setup on the current LA. TTT does not work with this kind of scenario.
I do not understand
It's possible that the call is encrypted in which case there will not be any call following.
Mostly open calls

I will record a video soon.
