First, thank you thank you thank sq5bpf , I tested the filter and it seems to work perfectly , only thing I would ask, do not know if I expected, but there is' way to save the filter ? I noticed from how I set that if I close and reopen the software , I lose the filter and I have to add it again . It would be even better to save the filters in my opinion . Anyway thanks again . Excellent job .

there is no way to save the filter. but you can pass the filter in an environment variable. some examples are included in the rxx script comments:
#example: match 1000
export TETRA_SSI_FILTER=1000
#example: match 1000-1099
export TETRA_SSI_FILTER='10??'
#example: match 1000, 2000-2099, 3000-3099, 4000-4099, and any 5 digit SSIs
export TETRA_SSI_FILTER='+(1000|[234]0??|?????)'
yes, setting the filter is one of the configuration options. look into rxx - there are already some examples there.
so for example add this to rxx:
export TETRA_SSI_FILTER=1000
export TETRA_KEYS=lRff
the last line is just like pressing l (logging), R (record), and f twice (enables inverted filtering).
so the receiver will play everything, except conversations with SSI 1000
i've posted documentation for the new telive version on github

Thanks for the software and all the explanations.
I set up all under Kali Linux and after many hours fighting, I see now data and listen to garbled voices. Probably these are encripted signals because air encryption is set to 1.
My problem now is that everytime I change frequency in gnuradio-companion, fft window freezes and nothing seems to work until I shut down linux and begin all process again.
I have read a possible reason could be I need to restart ./receiver1 1.
Anyone can point me on how to restart ./receiver1 1?
Thanks again.

Try this
When you change Frequency in GnuRadio you need to restart ./receiver1 1, go to the Terminal window this is running in and press CTRL + C, then press the up arrow and enter to run receiver1 1 again. HTH

Anyone who has updated to the latest version of telive, how did you update ?
Am I right in thinking I need to run git pull http://address in terminal, I done this but it only seems to download any new files. Do I need to rerun makefile or make ?
Tried reading up on how to properly use GIT but heck, my heads melted :/
I would love to take advantage of the SSI_Descriptions.
Ta!
Edit : I opened rxx and added export TETRA_SSI_DESCRIPTIONS, In the ssi_descriptions I have added my SSI and Name, when I run ./rxx and this SSI is in use it still shows as SSI.

Thanks! It worked although using CTRL + Z
^Z only suspends the process. ^C is the correct key to kill a process in linux (and other systems).
but you don't need to restart rxx when changing the frequency using the input boxes/sliders. you only need to start it everytime you close the flowgraph and start it again
if it really hangs after correctly changing the frequency, then this is a gnuradio or rtl-sdr bug. probably many people would have reported it already.

obviously after you update the files you need to recompile (run make etc..). the new version has a version number besides the name, so if you see v0.9 you know that you recompiled it correctly.
btw radioreference is really not a linux support group. find someone you know that has a basic understanding of linux and he can help you with this (and you can show him the radio stuff in return, so you can both have fun and learn something)
there is already a ssi_descriptions file there, just edit it. if you don't fiddle with the env variables it will read the file in the local directory

Completely understand, I have come along quite a bit on Linux since I started using TELive, Linux is now my main OS, I have never needed to update before so that was my first time which is good, I thought it would be easier to ask here since a few people have already managed to run this update.
I managed to get this working by running make, thanks for that.
I realized that just after I posted my edit, I removed the variable, SSI Descriptions are coming through now.
Hello in my area , the public transport service that SSI from 05590001 to 05590599. I would set in SSI file description everyone the same name, such as " Public Transportation " to display , there is a way to set a specific range of SSI the same words ?
no
but remember this is linux, so you can just generate the config magically with one simple command:
seq -f "%.0f Pub.Transport" 5590001 5590599 > ssi_descriptions
(or use >> if you want to append)
i'm not sure how the software will behave with 600 of config lines, but it shouldn't be a problem (maybe at 10000 lines? or 100000? haven't tried it)

Like many others I asume I have the problem that my laptop won't support the 203x60 window of Telive, the max size is 203x54.
Is it possible to make the status and message window floating in an own terminal session? Then the mainscreen fits on the screen and we don't have a garbled screen.
If not, no problem I'm a very happy user

no
i have a 1280x800 screen, and 203x60 is the largest xterm that i can fit there. i use an xfce destop, with small window decoration (the "meenee" scheme), and have only one panel, which is vertical on the side of the screen (16:9 screens are too wide anyway, so a vertical panel on the side of the screen is better)
one of the reasons that i will not do it is because i'm thinking about the next version, and this will have a totally different interface, and i will try to design it to fit in smaller xterms (preferably 80x24)
btw try running the xterm (or rxvt) fullscreen without window decoration (check on google for ways to do this), and you should have a big enough screen.
If not, no problem I'm a very happy user
i'm glad you like it

Has anyone written a simple script to launch the various xterm windows and commands for this that they could share? Id be very grateful. Please pm or email direct if that's more convenient. TIA

i think this would be a bad idea, but this is only my opinon.
please if someone publishes such a script, then make it idiotproof, and write everywhere that if this software doesn't work, then the user should try to run it as described in the manual.
