If you have problems installing Nova on a previous Phantom system, see installation section, sticky, to upgrade your compilers to work for Nova.

Quotei have do the Setup first with RTL Sticks .. but i have 3 SDRPlays .. what can i do to use this receivers?
do i run the compiler again?
RSP1A work fine with Soapysdr driver.

Please start:
novasdr-server setup -c ./config/config.json -r ./config/receivers.json
and add new sdrplay device(s)

or copy/paste my receivers.json
{
  "receivers": [
    {
      "id": "rx0",
      "input": {
        "accelerator": "none",
        "audio_compression": "flac",
        "audio_sps": 12000,
        "brightness_offset": -9,
        "defaults": {
          "frequency": 145675000,
          "modulation": "FM"
        },
        "driver": {
          "format": "u8",
          "kind": "stdin"
        },
        "fft_size": 131072,
        "frequency": 145000000,
        "signal": "iq",
        "smeter_offset": -30,
        "sps": 2048000,
        "waterfall_compression": "zstd",
        "waterfall_size": 1024
      },
      "name": "2m"
    },
    {
      "id": "rx1",
      "input": {
        "accelerator": "none",
        "audio_compression": "flac",
        "audio_sps": 12000,
        "brightness_offset": -7,
        "defaults": {
          "frequency": 3675000,
          "modulation": "LSB",
          "ssb_highcut_hz": 2900,
          "ssb_lowcut_hz": 200
        },
        "driver": {
          "antenna": "Fan Dipole",
          "channel": 0,
          "device": "driver=sdrplay, label=SDRplay Dev0 RSP1A 223500B399, serial=223500B399",
          "format": "cs16",
          "kind": "soapysdr"
        },
        "fft_size": 131072,
        "frequency": 7500000,
        "signal": "iq",
        "smeter_offset": -30,
        "sps": 10000000,
        "waterfall_compression": "zstd",
        "waterfall_size": 1024
      },
      "name": "HF"
    }
  ]
}
and then edit with hand.

My startup script for this receivers.json is:
cd ~
/usr/bin/killall novasdr-server
sleep 6
rtl_sdr -g 48  -f 145000000 -s 2048000 - |novasdr-server -c config/config.json -r config/receivers.json

73!

Bas, calm down :) ...
I'm just writing what strikes me or others ... it's already working very well and a few people should test it and see ... and if you don't write anything, you can't do anything else ... or better

No. Not at the moment or you need to start coding yourself.

Did you miss the point that this is a BETA-release and it has many bugs.

It's a very early beta. Short answer, no. There are more problems to fix then a s-meter.

Phantom has all, but can't do what Nova can. Did you know that just a week ago, we where in Alpha-demo state?

Many changes are going to happen de next weeks/months...be patient...

It will not be 'release' state until June or so.

Beware, Nova is a complete RE-WRITE, it's not Phantom.

Plans for Nova a BIG real BIG. But it's moving step by step.

You can alter the s-meter in dB's, for now that is all there is.

Steven has his own pace of doing things. It will get there....I do not know when.

General Discussion / S-Meter / Squelch
Last post by tuvok - 03 Jan 2026, 20:26
is this possible to calibrate the s-meter and the Squelch?

- the squelch will open all the time

- Many users of my SDR say that the S-meter is not working properly, and they ask if it is possible to reinstall the S1-9+50 system as a graphic.

Lower the gain setting, and or change receivers.json to make it less bright.

All docs are here: https://github.com/Steven9101/NovaSDR/tree/main/docs

See this doc: https://github.com/Steven9101/NovaSDR/blob/main/docs/CONFIG.md

Play with: "brightness_offset": 0,

Or edit the gain.
