First, we will need to find some TETRA signals.

(, Normal (Uses 2 SDR# and 2 Dongles) with TETRA Demodulator and Net Remote plug-ins, Simple (Uses 1 SDR# and 1 Dongles with some features not available) with TETRA Demodulator and Net Remote plug-ins. And work in 32 bits, ill try what you mention of the fft window. In the top right enter as a search term "en 300 395-2" and click the button to select Search Standards. Traceback (most recent call last): N O its not, i have wavecom and that decodes tetra fine in windows. So, I would say that is a pretty comprehensive no!

It works by using two dongles, one to monitor a TETRA trunking channel, and the other to decode voice audio, although a single receiver mode is also available which works with a reduced and fixed bandwidth. Since then OpenEar has undergone massive developments, not only improving upon the TETRA decoder, but adding DMR, ADS-B and POCSAG decoders as well as a waterfall display.

He then demonstrates reception of an amateur radio DMR repeater, reception of POCSAG pager messages and finally reception of ADS-B aircraft messages. am i on the right track ?
