 7.5.2024 Experimenting with QCSuper + Huawei e3276 https://github.com/P1sec/QCSuper VirtualBox Windows host - Ubuntu 22.04 LTS quest OS Huawei e3276 mobile broadband 2G, 3G and LTE Win 10 driver for the e3276 does not exist. USB sharing to Ubuntu. I selected the Huawei device in Guest OS/VirtualBox, no permanent selected USB device filtering in VBox USB settings. Ubuntu recognizes it as mobile broadband device. e3276 is conneted to USB host with many other devices connected to the same hub. The connection is somewhat unstable in Ubuntu probably because of hub connection. Better to use without USB hub and VirtualBox. In Ubuntu there may be modem manager etc settings to properly set up mobile broadband device. Enable the diag port AT$QCDMG (pip3 install atcom)   sudo ./qcsuper.py --usb-modem /dev/ttyUSB00 --wireshark-live succeeds to start (despite port connection being a bit unstable) and launches Wireshark 4.24. Wireshark founds multiple problems .... maybe it is better to us...

27.10.2022 SDR# TETRA plugin raw data output Many years ago the first TETRA demod plugin for the SDR# featured UDP port 20025 demod raw data output. This SDRSharp.TETRA.dll plugin also required M-SYS2, pacman and Tetra-RX to display TETRA decoded data in net info window. The plugin works without M-SYS2+Tetra-RX and outputs raw data to UDP port 20025.
