It would be a very convenient functionality to be able to start Gqrx DSP and Remote Interface TCP Server automatically when the application launches.  I can not find how to do it in 2.17.6.

Plugged your question into a search engine - it's 'AI' gives me this

"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>

Yes, launching the remote API server works with this:
[remote_control]
enabled=true
However, it is not clear how to start the DSP processing on startup. The [DSP] section only has the DSP setting properties, with no indication of how to enable launching it automatically.

It is not a built-in function, but can be accomplished by sending a command via UDP to gqrx.
