You could try
TETRA Trunk Tracker (also know as
TTT) and it's for Windows.
This is a plug-in for SDR# (TETRA Demodulator) and a stand alone program to control SDR#+Plug-in and handle the calls across the network.
Many different features are provided, see the documentation.
Can use with one or two SDR dongles (supported by SDR#) which will provide a different feature set.
Has PDF documentation for setup and usage.
There is a mega thread
here with many answers to possible questions and the latest released version (link to DL in post)
here.
NOTE: It is recommended to use an older version of SDR# (unskinned v1716) which can still be downloaded from Airspy.
This version is the last version before it became bloatware.
Just don't go to the Airpy forum and ask for support for it as they will tear you a new one.
There is a off shoot project called TETRA Network Monitor (TMN).
This allows to monitor multiple MCCH at same time.
This not as developed as TTT but you may find it of interest.
