Hi Wolfgang,

idea is:
You must have some kind of reception, you didn't have it yesterday and today.
Volume slider at minimum, no squelch.
Clicking the FT8 button activates decoding, you have to wait a bit.

The thing even works for me 

Recording and downloading work the same, there is no date and frequency on the recording,
I guess that will be in some version in the distant future.

I did all this through the nginx proxy server.

Good Morning All
Today, I checked all functions on my new NovaSDR installation and saw, that FT8 decoding is not working and if I record a station nothing will happen if I click on the download button.

Audio is set to audio_sps = 12000 and the filter is set to 3.7 kHz

Any idea why?

Phil, thank you so much! That definitely helped. It looks great now.

Sure, but you have to setup it yourself.

If you run into problems, I will be more then happy to help solving it.

Thank you very much!

Now I'll try to follow in your footsteps and hope you'll support me if I need guidance.

You should test if your phone ISP is using CGNAT or not, most do and such you can't run servers without some sort of tunneling.

Find a Linux expert to assist you, as without knowledge it will be hard to setup.

You have to build the server yourself, with e.g. HP EliteDesk with an Intel Gen6 or newer CPU that has a build in GPU so you can enable OpenCL to do wideband.

Receiver we use it the RX888MK2 that must have the thermal-mod in place, you have to check for this, else it will burn.

I use this CPU: Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz (any newer Intel should work fine with internal GPU)

All info is here: https://github.com/Steven9101/NovaSDR

But like I said before, you need an Linux Expert, and yes it must be Ubuntu 22.04 (any other Linux or version can give serious problems)

You also will need a very big battery, as it will probably consume >50W/h in total.

You can use smaller devices like the RSP1A, that can do about 8Mhz wide.

If this is too hard, better go OpenWebRX or get the KiwiWebsdr, as this stuff we run is NOT plug and play and required a lot of knowledge. The Kiwi is plug-and-play and uses little power.

Hello everyone, I'm in Italy and would like to activate a WEB SDR.

I'm not an expert in software and PCs.

I have experience with antennas, radio reception, and DC hardware.

I'd like to place it high in the mountains with a solar panel and battery.

I therefore need plug-and-play equipment.

Our telephone network is 4G.

Try to explain to me what I should purchase and where, then how to assemble it.

It must have the 26-28 MHz AM FM LSB USB band, plus any other bands.

Thank you.

Ok, I see your screenshot showing the 2 meter VHF section. You can edit the file : /NovaSDR/frontend/src/waterfall.js and
change the following code :

From :
        { name: '2M HAM', startFreq: 144000000, endFreq: 148000000, color: 'rgba(50, 168, 72, 0.6)',
          modes: [
            { mode: MODES.CW, startFreq: 144000000, endFreq: 144100000 },
            { mode: MODES.USB, startFreq: 144100000, endFreq: 144300000 },
            { mode: MODES.FM, startFreq: 144300000, endFreq: 148000000 }
          ] },

To:
        { name: '2M HAM', startFreq: 144000000, endFreq: 146000000, color: 'rgba(50, 168, 72, 0.6)',
          modes: [
            { mode: MODES.CW, startFreq: 144000000, endFreq: 144100000 },
            { mode: MODES.USB, startFreq: 144150000, endFreq: 144500000 },
            { mode: MODES.FM, startFreq: 144975000, endFreq: 146000000 }
          ] },

Then recompile the frontend and see if that fixes it.

What I found was no matter what you did, the ITU region was stuck on region 1. To allow my frequency range to match the bands in ITU region 2, I had to edit the file : /NovaSDR/frontend/src/components/BandsMenu.svelte

And change the following code from return 1 to return 2
  // Get ITU region from server location
  function getRegionFromLocation() {
    const coords = maidenheadToCoords($serverInfo.location);
    console.log(coords)
    if (!coords) return 2; // Default to Region 1
    return getITURegion(coords.lat, coords.lon);
  }

Now to answer your question, I cannot because the system should be defaulting to region 1. What are you seeing that is not matching region 1?

Hi All
This solution from Gianni HB3XDC works great for my new NovaSDR Server on Ubuntu to start the NovaSDR server if I remotely switch of the 230V Power from the HP Mini PC.
