control and listen tetra unencrypted network
hi all, I would like to know, if someone tested the network in ex-jugo states (like is Slovenia)? In our country use no encrypted network (clear, no TEA encrypted)... So, i wonder if is possible with osmcom project to listen (real time) to tetra groups? If is possible to do this with DVB-T reciver, like this: http://www.youtube.com/watch?v=Z0hEquzLsWU product: https://www.cosycave.co.uk/product.php?id_product=220 This means that you can monitoring all tetra network, but not for voice,because i need a voice decoder? Thanks for help and answers.
I'm using rtl-sdr devices to decode tetra traffic at south of Spain with no encryption. It's possible to decode speech messages but no call identification is available so the files are named by frame number. Jesús F. 2012/7/8 Media <media06@gmail.com>

Thank you for your answer. So this mean that u can see informations like ISSI, ID group? Speech messages, you mean the SDS messages or talk on the group - real time? have you full access to all group in real time? Sorry, i have no experience with osmocom project jet; i having a few motorola terminals for testing, so this is my next step. Thanks, Regards. 2012/7/8 Jesús F. Trujillo <elyeyus@gmail.com>:

Nothing, the only information I can retrieve are the speech data (voice files called traffic_X.wav, where X is the frame number 1 to 60), cell information packet (frequency, encryption, etc...) and D-network-brcast packets (with neighbour cell information). So no SDS nor data packets. I think that if you want to retrieve this you need to implement that part in the svn code. In order to get call information you need to intercept call-setup process but nothing in the actual code base takes care of this. Regards, Jesús F. 2012/7/9 Media <media06@gmail.com>

Hi, i use osmocom + FCD Funcube and i can listen all in near-realtime, the network in my area use no encryption. I have made some mods to save te traffic file with the number of the GSSI or the SSI. I have a motorola mth800 and some SELEX VS2001 and PUMA T2 2012/7/8 Media <media06@gmail.com>

Would you share your implementation with us? Where do you extract the GSSI and SSI information? Regards, Jesús F. 2012/7/10 Edoardo Rispoli <edoardo.rispoli@gmail.com>

if you have it please share with as. I would like to know how it sounds and looks like this in practice? Some demos in video? How quality is TMO talk which you should hear? Is this mean that u can select GSSI (with filter) and listen conversation in unencrypted network? if that true that exploration is worth the time and money, but otherwise if u can just watch and observe the frequency of events - this isn't exactly a successfuly... 2012/7/11 Edoardo Rispoli <edoardo.rispoli@gmail.com>:

I have inspected the code and seems that will work flawlessly. I'm doing some research in order to split the speech code to another source file and I will try to link the ETSI codec (that code can not be redistributed) in order to get an online decoder. 2012/7/12 Media <media06@gmail.com>

thank you Jesus, the mod is very simple but very useful! in my area there is a only tetra network (52 bts) with many services, so i can distingue each service by the gssi. for the on-line decoder, i think that is better to maintain it off-line.... 2012/7/12 Jesús F. Trujillo <elyeyus@gmail.com>

Hi! I.m also interested in the mod for the traffic file. I.ve been looking for it. I started to take a look to the C code to know how to get the gssi and the ssi to save the traffic file. I.m working with osmocom and tv-tuner-usb. Regards! -- Javier Coso
