Hello All
Whre are a discription of all functions / commands in the config.json

What is this fuction: "ws_per_ip": 50

Interesting is, that after a certain time, the NovaSDR goes into a sleep-mode.

And the markers with the file markers.json does not work in my case.

WS per IP is WEB-SOCKETS per IP, meaning you can limit the number of sessions per IP.
Beware a websocket isn't a single session, it could be more.
Typical, no need to change it.

Did you put your markers in config/overlays/ ?

Also there is a mistake in your markers at the bottom:

      },
      {
      ]
}

that must be

        }
  ]
}

The last marker end with } but then you say , and {

The last marker should be this, including the end of the file:

        {
            "frequency": 439475000,
            "name": "ON0LG",
            "mode": "FM"
        }
  ]
}

As such they do not work. Also you need to zoom in quite a bit to see them.
