Few things, you probably had Phantom running before, so you needed to update npm and nvm engines to the latest.
Then the frontend will compile just fine.

The backend doesn't compile if you don't have a Vulkan GPU, as it's missing the Vulkan dependencies. You have selected NO on VKFFT.

I have reported this already to Steven. But he probably tested the beta on a NEW installation, not on excisting one.

i think this is a nightly and repo thing.. with a standard ubuntu we can not use it

Your Rust version is to old, please update it using curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

And then restart the system and retry.

PS: i can not Upload pictures.. the Uploadfolder is full ..

QuoteRecording 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.

Sending "evidence" to the forum doesn't work and the file is about 384kb.

Quoterecorded_audio.zip There was a problem during the uploading of recorded_audio.zip.
The upload directory is full. Please contact an administrator about this problem. 0.4 MB

The joy never ends!

QuoteThanks for the Hint - it is working now :-)

I'm glad it works, I came to this solution through the "futile attempts" method.

Hi Darko
Thanks for the Hint - it is working now :-)

I will install the new NovaSDR tomorrow at our remote DX-Site at 1'660m and the NovaSDR will run over our Reverse Proxy Server :-)

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?
