[Ground-station] DVB Monitoring, was: Need advice on DVB-S2 modem

[Michelle Thompson]

Wireshark is the most popular and widely used network packet analyzer. GSE
packets, and many other types of packetized data, can be analyzed using
Wireshark.

I believe the record feature captures raw data, which then can be usefully
analyzed by a variety of tools.
