Tetra decoding

[RonnieUSA]

Try changing from 2.4Msps, to 1.024, and see if that clears it up any.

on Windows??

hello
sorry for the question but it is not practical with linux systems wanted to ask if it is possible to emulate the system under Windows 7 or otherwise if the porting is possible ..
Thanks but I admit my ignorance though I'm tempted to try it but I know that I will have problems hii
thank you
P.S. I understand that my request for a programmer and as a blasphemy ..

blasphemy is where someone does not care to read all avaliable information and asks questions

one of my posts has a link to a tutorial by rtl-sdr.com that shows how to install ubuntu and this software on a virtual machine under windows, look at that (not that i endorse this method, it won't give top performance, but you will get a taste of what this software does)

IQ recordings (SDRsharp 16 and 32bit float, 2.4Msps) here [...]

i can't seem to read this file. i assume one channel has i and the other has q data, but i can't seem to read it. does someone have a specification how sdr# records these samples?

hi
I used the term blasphemy ironically not 'cause I had not read the tutorial ..
I said a real porting that could run on windows system on real not virtual machine that I realized the fact and indeed the performance is limited and does not do justice to your work
all quà
sorry but I speak bad English are Italian in Rome hiii

Everything works fine now on linuxmint 17 except this error in gnuradio:

(python2.7:2955): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed

i don't have this bug, but this is what i found on the internet:

this is a qt bug. if gnuradio-companion keeps running, then don't worry about it

if not, then run qtconfig and select gui style "cleanlooks"

i hope that dsd+ will decode tetra soon...

any live tetra systems in the united states ?

Voice codec can be downloaded from ETSI and compiled for your own use, but there may be a problem if you want to distribute them in binary form. Any TETRA receiver software ready to use could put its author in serious legal trouble.

Hello , congratulations for the software , I'm trying to install telive on ubuntu 14.10 for try in the Italian system , someone managed to get it working on Ubuntu ? There are variations from the guidance presented on sdr - rtl ?

Voice codec can be downloaded from ETSI and compiled for your own use, but there may be a problem if you want to distribute them in binary form. Any TETRA receiver software ready to use could put its author in serious legal trouble.

actually it would be interesting to know the status. the codec source has no licensing information, neither has the page that it can be downloaded from. ETSI has some IPR search form, which i wasn't able to use (probably too much stuff blocked on my browser, didn't really try much).

it would be interesting:

- if i can redistribute the source? (along with some install scripts that patch and compile it)

- if i can redistribute binaries? (if the project is non-commercial, and source is included) - probably not

any lawyers here?


btw mbelib also has a similar problem, and still people redistribute dsd and dsd+, and didn't have any problems (yet

any problems?

in the tutorial here: RTL-SDR Tutorial: Listening to TETRA Radio Channels - rtl-sdr.com they use ubuntu 14.04 32-bit. 14.10 will most probably work too.

if you're using a 64-bit system, they you will have to compile the codecs for 32-bits. there is a description in the documentation, this is for debian but probably will be the very similar for ubuntu. basically if you know what you're doing you shouldn't have any problems

Hello, I have run aground, running the command receiver startup cd ~ / osmo-tetra-sq5bpf / src ./receiver1 1, the terminal it says command not found. If regarding the installation of package gnu-radio, I find that the make command fails:

From what little I understand of ubuntu, if the make and failed means that the receiver has not been created right? how can I do to fix?
thanks

[...]From what little I understand of ubuntu, if the make and failed means that the receiver has not been created right? how can I do to fix?

it's hard to tell, this script is used by a lot of people (not only for telive), and it usually works for them.
you can try to run verbose:
./build-gnuradio -o -v
and see what error you get.

 

[hansheesbeen]

System works great. Thank you!

 

[sammy3418]

System works great. Thank you!

Love to see a video of this working !

 

[sq5bpf]

System works great. Thank you!

thanks. i hope you like it

i understand that you installed under linux mint? (64 or 32 bit?)

 

[hansheesbeen]

Yep installed under mint 17 32bit later i make al list with the changes for mint

 

[sq5bpf]

there is a new telive version out, with slightly different colors for more redability, and a way to change verbosity (using v and V keys, less verbosity shows less logs in the status window), and showing text SDS directly in the status window (previously they were only in the logs)

also i have reports of a crash in sds decoding routines in tetra-rx (but only for some sds), this will be fixed once i nail it.

 

[sammy3418]

Hi I seem to have gotten somewhere using the tutorial provided... I can get the gnuradio radio going, but am I stuck on the part (Double click the variable labelled ppm and input your dongles particular PPM correction value) I have a NooElec R820T dongle! Do I not need drivers for this installed 1st? Have I missed something? All the software is installed with no errors... Running ubuntu 14.04 !

Thanks

Sam

 

[sammy3418]

Installed everything as pair the tutorial... But when I run RTL_TEST I get his
sam@ubuntu:~$ rtl_test
