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.

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.
