It only works with Firefox and not with Edge and Chrome - very strange.
The mouse wheel works for me in Firefox, Google Chrome and
Vivaldi browser (OS is Linux) on your NovaSDR server.
 I just tried the 1 and 9 kHz mouse wheel on your NovaSDR server, everything works.

The secret is that you have to reload the page with CTRL F5,
click on the tiny gear in the upper right corner of NovaSDR,
select the desired wheel step and it works on that browser. 

When you come with another browser, again CTRL F5 to reload the page,
click on the gear in the upper right corner of NovaSDR,
change the desired mouse step....it will be remembered until
you delete the browsing history in the browser.

Now, what is the secret of setting the background image in NovaSDR,
share with us, please.

Best regards,

Hi Darko
We modified the code in order to use the middle mouse wheel in the frequency window.

It only works with Firefox and not with Edge and Chrome - very strange.

Hi Darko
I changed to brightness_offset = -10 and will install the mouse wheel fix tomorrow.

Thanks

QuoteThank you very much for the markers.json.

I like to edit that markers.json and add new stations that I hear.
I have personally heard each of these markers, checked the frequency and station name,
and manually entered them. I am happy to help.

You can hear other stations on some frequencies, you can edit that yourself.
 

QuoteBackground picture is not really important but to have the mouse wheel working in the frq. window would be great as in PhantomSDR v1.54

Please, see this: Mouse wheel step on Phantomsdr+ v2.0.0 (quick fix)

When I was dealing with this I managed to change the mouse wheel step, it worked. If you decide to do the same,
before changing the original files with the ones I edited, make a backup of the original files.

After the change, you need to do npm run build in the frontend or frontend/src directory.
App.svelte it is not necessary to change.

Please edit your config-rx888mk2.toml and change line brightness_offset = 0

to brightness_offset = -10
or more in minus, you have too much brightness of the waterfall.

Emmanuel SV1BTL helüed me remotely via AnyDesk to install his version of the PhantomSDR-Plus.

Thank you very much Emmanuel.

It worked, but my HP ProDesk 400 G2 Mini PC with only 8GB memory is not strong engough to run PhantomSDR-Plus even without or with accelerator.

So I just ordered additional memory for this PC.

8GB is more then enough to run Phantom. It only depends on the CPU.
But most seem to have an I5-6500 or better, that will run Phantom/Nova without problems.

I use the EliteDesk Mini with the i5-6600 and it runs fine, even tested upto 40MHz BW, no problem.

But beware, I do not run a desktop on it. If you do, you better turn that off until you need it.
As a desktop will eat GPU-power and you need all for Phantom. As you speak about Anydesk, you run a desktop too.
More memory won't help, you need a lot faster CPU+GPU to do Nova+Desktop.

Hello Darko
Thank you very much for the markers.json.

NovaSDR supports markers.json but background image not.

I put my background image in
NovaSDR/frontend
NovaSDR/frontend/build
NovaSDR/frontend/build/assets
NovaSDR/frontend/src/assets

then npm run build,
there are no results.

I've attached my markers.json zip that works.
It needs to be unpacked into the NovaSDR directory.

PS:
This with the background image is not a bug, but a new feature!
 

Quote from: hb9ryz on 05 Dec 2025, 07:43 a.) get a background picture
b.) use the mouse wheel in the freq. window
c.) get a good marker.json to display freq. hints in the waterfall

a.) According to app.svelte (v.2.0.0) your background picture is located in place (line 1852 of the code):
background-image: url("/assets/background.jpg"), url("/assets/background.png");
If you have not any picture with this name in this folder, you can place one, but with THIS (background.png) name.

b.) It seems that v.2.0.0 does not support this function yet, compared to the previous versions.

c.) I cannot see the file markers.json that existed in the previous versions. I don't know where is this located (if exists), but the fact is that I cannot see any other v.2.0.0 server to have stored frequency markers and displayed them in the waterfall at the bottom of this.

Hello Emmanuel, Darko and Phil
My NovaSDR (PhantomSDR Plus v2.0.0) is now running great 😊

The main mistake was that, out of sheer habit, I plugged the RX888MK2 into the wrong USB port (USB 2.0) instead of the USB v3.0 port.

This is because the two HP mini PC EliteDesk and DeskPro look almost identical from the front, but have different USB ports on the back.

Thank you very much for your support and hints - thats Ham Spirit :-)

There are still three tasks to fix:
a.) get a background picture
b.) use the mouse wheel in the freq. window
c.) get a good marker.json to display freq. hints in the waterfall
