Thanks. I'm struggling a bit how to get a GSMTAP dissector in wireshark. I need to recompile wireshark in order to get there, do i?

Yes, you will need to compile one of the 1.5 development versions of wireshark. If you are using Ubuntu there are some PPAs with wireshark 1.5.1.

Thanks. I've found a PPA @ https://launchpad.net/~dreibh/+archive/ppa it has GSMTAP as a protocol.

I still don't have the right architectual image of GSMTAP i think. Do i need to direct wireshark to sniff on the same interface that tetra-rx opens its udp socket on, with a port filter, or is there a pseudo interface that listens for raw packets on the same UDP port?
