"Gqrx, an open-source software-defined radio (SDR) receiver, can be configured and controlled through command line options. To start Gqrx with a specific configuration file, use the -c option followed by the path to the configuration file. For example:
-c [ --conf ] arg: Start with this configuration file.
Additionally, Gqrx supports other command line options such as:
-h [ --help ]: This help message.
-l [ --list ]: List existing configurations.
-e [ --edit ]: Edit the configuration file before using it.
-r [ --reset ]: Reset the configuration file.
-s [ --style ] arg: Use the given style (fusion, windows).
For detailed tutorials and how-tos, visit the Gqrx website:
https://gqrx.dk/.
To ensure optimal performance, it is recommended to run the volk_profile utility before starting Gqrx."
So, I'd SWAG you could configure 'Run TCP server' in the config file and then launch it with: gqrx -c <name/location of file>
