Tetra decoding

[grosminet]

Airspy in working with UDP . I changed the grc in order to make it work . fifo is much more efficient , more datas , faster decoding . Udp is as same level of decoding in UDP than the funcubepro plus

It had to be tested

Hi all, i'm trying to make a tetra raspberry based portable device, similar to a scanner. Its possible to show a rxx window but only with information about the decoding voice? For example to show on a LCD screen the SSI talking now, but only the ssi talking

a smaller interface is planned for the next major version (still in concept phase)

Can somebody tell me (preferrably simply) how to set up Wireshark to work with Telive?

Ce sont deux systèmes différents aucune nécessité d' utiliser wireshark

telive doesn't use wireshark. you probably mean tetra-rx

the patched osmo-tetra-sq5bpf will send gsmtap messages on localhost, just as the original osmo-tetra software does. so just run wireshark and sniff the loopback interface and you will see the gsmtap messages

Thanks for your reply!

I cannot see lo0 / loopback interface in Wireshark's interface options o_0

Cannot edit my message but I had to run Wireshark as su to see the lo0. Now it's working fine

it's kind of obvious that you need root privileges to run a sniffer

Segmentation fault (core dumped) for the execution of telive

Hello,

here is my concern I installed tetra listener by running in a terminal telive which this is the procedure cd telive then ./rxx here error Segmentation fault (core dumped) and my second problem is when I open a file telive gnuradio and that I execute its been a blank page top block.
in waiting for your response

cordially landry

 

[sq5bpf]

here is my concern I installed tetra listener [...]

but this software has nothing to do with tetra-listener (both are based on patches to osmo-tetra, but that's about it).

i haven't looked at that code much, but their patches to osmo-tetra shouldn't be too hard to apply to osmo-tetra-sq5bpf, so you could use both software at the same time. if you know some C, then this should be doable, if not then forget it. anyway you're on your own

sq5bpf,

After your wonderful USB install i like to learn more so install Mint 17.3 and GNUradio.
The problem is,
when install telive_1ch_simple_gr37.grc i only get ones the FTT+Freq screen pop up.
After that one time it never pop up again.

I used this tutorial to instal all the goodies

sudo wget https://raw.githubusercontent.com/sq5bpf/telive/master/scripts/install_telive.sh
sudo chmod 755 install_telive.sh
./install_telive.sh
Running the Software
1. Open a terminal window and browse to
2. ~/tetra/osmo-tetra-sq5bpf/src and run ./receiver1 1.
3. cd ~/tetra/osmo-tetra-sq5bpf/src
./receiver1 1
4. Open a second terminal window or tab and open a specially sized xterm window
using the following.
/usr/bin/xterm -font fixed -bg black -fg white -geometry 203x60
5. In the xterm window, browse to ~/tetra/teliveand run ./rxx.
6. cd ~/tetra/telive
./rxx
7. Open another terminal window or tab and browse to /tetra/bin and run ./tetrad.
8. cd /tetra/bin
./tetrad
9. Open another terminal window or tab and open GNU Radio Companion by typing the
following.
gnuradio-companion
10. In GNU Radio open the telive_1ch_simple_gr37.grc file which is found in
~/tetra/telive/gnuradio-companion.

For some reason i am unable to edit the Freq,gains or any other functions in the flow chart screen,It just fades out within 30 secs of launching,While i cannot make any changes to it,It still does not stall,As the spectrum analyzer still moves.

Output is showing as 000000 continuous.

I can edit the values if i have the USB dongle disconnected,But that is not much good.

Hello sq5bpf,

After play for days with your wonderfull USB solution, appreciating that USB solution very much,
i install MINT 17.3 and GNUradio with telive on a new HDD.
Working is oke no problem with that.

Days and many deep nighty hours i try to make those 4x easy startup icons you made in USB solution,
try all kind of ways and settings but i get stuck in it...

A small hint or tip how you make those 4x easy startup icons, that will be great
In behave i thank you for any hints or tips

 

[hamradionl]

After days and several nights i still get stuck in the part mentioned above.
When there is any advice it be very appreciated.

Hello sq5bpf,,
For linux users, do you know a way if possible to use GQRX to pipe the audio into telive ?
GQRX having a more user friendly Gui to use the 'older' or 'none wizzkids" hamradio user.
Gqrx SDR – A software defined radio powered by GNU-Radio and Qt

new tetra frontier

thank you very much sq5bpf

could not believe that buzzing noise become meaningful , thanks for redefining the frontiers of SDR technology my good friend.

i am using your bootable image , to my wonder the telive demo works easily and i am able to listen to lots of traffic in my country "will be sending your logs privately" my machine is COMPAQ I3 . and works nearly ok.

if i try to run telive using the terminal/exterm launch procedure , nothing happens.

but too much fun indeed, learned linux which was totally another universe for me.

once again thanks for your self and all other members who did light up the dark with their experiments.

73s.
