i can log the SSIs after the file has been saved. logging something while the audio is playing doesn't make sense, because the values can change over time.
is this ok?

That would be enough. With that info we can combine devices to groups, maybey even with some smart combining predict the gssi's more easy.

If we had it in the log while playing it would be nicer because of the real time filtering that can be done for external display of the ISSI/GISSI that are played at the moment.
Or a separate "log" file that contain the real time played info

I've made "git pull" with "new 1.9 beta version" and I've got core dump when I'm trying to run telive. Unfortunately I didn't make a copy of working version....

I think this will be solved with the implementation of an xrpc server... See this post: http://forums.radioreference.com/vo...are/302347-tetra-decoding-70.html#post2600111
so now you know why this was planned
another reason was to have a simple way to have an external program drive an LCD display. one way this could be used would be a raspberry pi with external lcd that could be used as a standalone tetra receiver/scanner.
but this is not at the top of my priority list at the moment.
Yes, I have read this. putting it in the log file will be a "quick" solution till XRPC Server is implemented.
With multiple telive's running is is nice to show in the log windows what is playing.
so you do not have to swap al the telive screens to see what is playing.

Segmentation Fault (./rxx 1.9 beta)
yes, i've seen it, and will investigate it next week. for now you can comment out the call to clear_freqtable(frequencies) in tickf() (this is somwhere around line 1478)

Tetra works, Many Thanks to Jacek (sq5bpf)
But i have any Problems.
First, my english is very poor sorry, i hope you can understand me. Speak anyone here the German Language and can help me? I am an absolute Linux Beginner. The Systems are running with Linix Mint 17.3 XFCE. I have more than one Computers installed with Linux and Telive. (Asus F200CA Netbook 2GB Ram + Asus X5DIJ 4GB Ram)
The 1. SDR is the known Black Stick, the 2.SDR the known Blue USB Stick from China. R820T Tuners.
The Antenna, an Diamond X300N, is on the Roof of the House, in 25m Height. The QTH is Central in the City.
First little Problem:
I have Python Errors in GNU Radio. The Error is:
(python:2436): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed
But Tetra decoding works.
Second Problem:
My local Tetra Network has 4 Frequencys around 426 MHz. 4 local areas with its own Frequency, but the same "Uncnown Network 215"
I am running telive_4ch_gr37_udp.grc with receiver1udp 1-4. It works, but i have "Too much Changes" in RXX Window.
I cant configure the other Way with 2 or more different Channels, my Linux experience is to poor.
Third and Big Problem:
The Tetra Network is from a local Transportation Network. Bus, Trams and Support Units, 1"Big Central Dispatcher Tower", 2 Depots.
The local Tetra Network is organized in 4 "User Circles".
1. User are all the Tram and Bus Vehicles.
2. User are all the Support Units.
These two User Circles are managed from the "Central Dispatchers"
3.User is the Depot One
4.User is the Depot Two
Depots are Managed from a local Operator. (Callsigns "Depot10" seeing on LA1 Frequency and "Depot30" on LA4 Frequency. in RXX Window)
My Problem: I dont hear any Mobile Vehicle (Tram, Bus) managed by the Big Central Dispatchers. I can See in RXX Window the Callsign of the Tram/Bus/Support Unit, but only i can hear the Big Central Dispatcher. Is a big "Self Talk" from the Central Dispatcher, i hear no Answer or Question from the Tram/Bus/Support Mobile.
But when the local Operator from Depot 1 and 2 talk with a Tram or Bus, i can hear Both ! The Operator and also the Tram/Bus! the complete Talk was played and recorded.
Why i dont hear the Talk betwenn "Big Central Dispatcher" and an Tram/Bus/Support? Where is the mistake? Has anyone a Tip?
I testet parallel with an second Computer, it runs on Upload Frequencys 10MHz lower, but there found no Tetra Signal.
mutessi on/off has no effect.
An other little Problem is simple for Linus Experts.
How can i make an "one Button Starter" for all the Programms
( 4CH grc, rxx, tetrad, receiver1 udp Windows 1-4, RXX Window) ? I have a blind Friend and its better he start only one Button for all the Programms...
The last Problem is the "Simple Slow grc"
On my other Netbook, Acer D250 with an old Atom and 2 GB Ram have i the Problem, that i cant Run the "1 CH Simple", the Window with the Spektrum Analyzer and Flowgraph is to big in Vertical Size, i cant see the Sliders für SDR Gain etc.pp. The Display has only 800x600.
How to Resize this Window?
I know that was just a lot, thank you all in advance.

hey , jacek thanks for the great software in linux, its running ok
companies tetra unencryted on 425.56 >429 mhz great audio output.
sometimes a little bug in telive , and crashes after inactive voice period
good luck.....73

Don't worry about this.
I quote from the telive docs:
Read the doc, it explains very clear how to deal with multiple channels. https://github.com/sq5bpf/telive/raw/master/telive_doc.pdf
Are you sure you are listening to all the frequencies of that LA? Press t to see a list of detected frequencies.
You are not going to hear anything on the upload freq's unless the transmitting (uploading) radio is near you and then (if telive can decode the upload directly, I don't think it does) you'd only hear that radio.
What do you expect it to do? The doc says this:
Read this topic, the answer is somewhere in here, don't know where exactly.
You can edit the block to make it more horizontal. Or, if you know the frequency, don't use the simple one.
I'm not an expert myself but now you have some answers hopefully.

hello and congratulations for all you have done for all om and swl with Telive ...
I am a beginner with Linux Ubuntu 16.04 on an acer aspire 1640 Z, thanks to the radio with gnuradio companion. always very interested in digital transmissions, DMR with dsd + and tetra with telive now thanks to your work ...
I have several problems unfortunately ...
1- "Despite having put" as xtrem 203x60, "I still have a window of 201x59", "preventing me from having" any 'slider' ppm, tune, gain etc ...
2- Despite "reading" all "read me" files, "I have a hard to start" a scan, or even a decoding on a known frequency, and "God knows" if "there is here "with strong signals," it's annoying "...
3- compiling my file 'en_30039502v010301p0.zip' at the last moment, it marks me "impossible to find aplay packages.
Help Help Help ... "I would be very happy" "work with your application" telive ...
And a question, how to serve me as sdrsharp receiver on another laptop and connect it to my acer linux with telive? with the help of a cable jack on the linux sound card input changes would be me easy? only to try? I'm in France and I am sorry for my bad english

tetra telive gnuradio-companion install .doc for kali linux iso
hello everyone, i have made a summary of my commands for linux in a .doc here for download...
first download kali linux 64 bit ISO on internet or 32 bit?
use cdburnerxp to burn the ISO file on a dvd.
make the kali installation on your laptop or desktop.... from boot....
startup kali and give all the command like in the .doc telive tetra gnuradio-companion sq5bpf
all is done in the "terminal" kali linux , be sure to type everything right -./ etc....and enter....
ALL the commands are correct . it is working exellent here. for unencrypted tetra
thanks for sq5bpf and finding here and there some info on the internet
