i've written a small patch to osmocom-tetra to send data via udp (i didn't
want to use gsmtap), and a crappy program to display/log/record/listen
live
the only interesting part for people on this list would probably be crude
d-setup, d-release and sds decoding. also the demodulator is stripped from
the gui, so that it can receive baseband via a unix pipe from some
receiver (gnuradio, but could use rtl_fm probably too).
