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.

Hello Guys,
i 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?

QuotePlay with: "brightness_offset": 0,

this was the Point thanks i have set it to -5 and it run

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.

my WebSDR is located in Germany near Eschwege

Locator JO51AF

it run .. i have disabled it .. the main problem was the old node and rust .. but this is standard on a LTS Ubuntu version .. i have add the repo for node and add rust as a newer night build on the user account ..

It would be nice if it were developed on stable, then people might not have so many problems... Above all, you need to know a little bit about it to be able to do that.

If you reuse a system that had Phantom before, it won't compile. Use this instead.

git clone --recursive https://github.com/Steven9101/NovaSDR.git ./nova-src

Go into the nova-src and try to compile.

cargo build -p novasdr-server --release --features "soapysdr,clfft"

For other stuff like OpenCL etc, see the docs.

Now go into frontend dir, but this one can fail.

npm ci && npm run build && cd ..

If it fails, you need to update modules...with commands below.

nvm list

Take latest stable version

nvm install 22.21.1

Make sure you use it and make it default next time

nvm use 22.21.1
nvm alias default 22.21.1

npm will probably error too, so upgrade it to latest version

npm install npm@latest

With a little luck it will all compile, now you can setup the default install with:

./novasdr-server setup
Then it will write the default starting files, you can edit them manually later or run configure instead of setup.

Hopefully installing goes well now.
