SDRplay receivers Soapy commands.

[Bas ON5HB]

Hi all,

I have been fighting with the SDRplay receivers to get e.g. rf-notch disabled, enabled by default.
Well, you have to name the key and option, like this:

Code Select Expand

    {
      "id": "rx3",
      "input": {
        "accelerator": "clfft",
        "audio_compression": "adpcm",
        "audio_sps": 12000,
        "brightness_offset": -3,
        "defaults": {
          "frequency": 648000,
          "modulation": "AM",
          "squelch_enabled": false
        },
        "driver": {
          "channel": 0,
          "device": "driver=sdrplay, label=SDRplay Dev0 RSP1A 1807098293, serial=1807098293",
          "format": "cs16",
          "gain": 35.0,
          "kind": "soapysdr",
          "settings": {
            "rfnotch_ctrl": "false"
          }
        },
        "fft_size": 131072,
        "frequency": 1024000,
        "signal": "iq",
        "smeter_offset": -30,
        "sps": 2048000,
        "waterfall_compression": "zstd",
        "waterfall_size": 2048
      },
      "name": "SDRplay RSP1A (LW-MW)"
    }


See below, else it will not work. Don't tell me why.
