Why doesn't markers.json work?

[ihweb]

I have put a markers.json file in the PhantomSDR-Plus directory, and I am sure the file content and format are correct, but it does not work.

Code Select Expand

{
  "markers": [
    {
      "frequency": 9000,
      "name": "Lightning",
      "mode": "AM"
    },
    {
      "frequency": 172000,
      "name": "SAQ Alexanderson",
      "mode": "CW"
    },
    {
      "frequency": 30000,
      "name": "Lightning",
      "mode": "AM"
    },
    {
      "frequency": 77500,
      "name": "DCF77",
      "mode": "CW"
    }
  ]
}

You can test the json file at the URL below, and the code you posted does check good.

What is the frequency range of your WebSDR?

Also, the markers.json file goes into the same location as your toml file and verify the rw permissions / ownership, etc. of the json.

      "mode": "CW"
    },

SAQ operates at 17.2 kHz, so the frequency in markers.json is 17200

You need to restart the spectrumserver and zoom in a lot to see them.

Did you put them in the Phantom-base-dir?

I made sure that the markers.json file is in the same directory as toml.
My websdr is 0-30Mhz, RX888.
And I also restarted start-rx888.sh according to the instructions

I don't know what happened, the system just doesn't show the marker.

This is my startup information:

Oh,thank you.   
It is almost normal now. It turns out that it needs to be maximized.
