NovaSDR is uploaded to the github, and is no longer compatible with PhantomSDR, beware of this. Also it's still in beta-stage.

I will make the bands menu dependent on the receiver and only show available bands in the 0.2.4

Quoteplease try it in the 0.2.3

In 0.2.3 this problem is gone.  :)

I confirm what Bas wrote about the ssb width.

I have a question, how to remove excess amateur bands from the drop-down menu?
Specifically, I have an RSP1A that works on HF with a maximum width of 10 megahertz,
in the drop-down menu I see a selection of bands that are unavailable in those 10 megahertz.

I edited bands.json, removed everything that is out of range,
non-existent amateur bands appear after every restart of NovaSDR.
The broadcast bands are gone, only the ones I can actually hear remain.

I think I'm not the only one who has this problem. :)

73!

Installed 0.2.3, problem still there. See picture.

See BW, when you select LSB again it will do 2.75KHz not 2.70 as should.

Also, when you type 3630 in LSB mode, then switch to USB the frequency changes to 3629.951

This is happening since you made the change 300-3000 for SSB possible, but it has more impact then just BW.

Hi!

go to http://websdr.heppen.be/

click to Broadcast/49m band, result is clean browser window,
must be reload page.

In my home, some problem when I click to 49m band.
Restart NovaSDR, nothing, restart computer, nothing, bug is there.

QuoteQuick fix:
Go to http://websdr.heppen.be/

Click to AM or SAM modulation and then select Broadcast/49m, no crash, it works!
 ;D

When you are on the AM band and want to return to the LSB band,
first select LSB modulation and then click on the desired band.

If you do not do this, you will have to reload the website.


Please, fix this.
Thanks!

Show us your websdr / My WebSDR in Testing Phase
Last post by ps7ti - 05 Jan 2026, 18:51
Even though it is still in beta, this has been the simplest, most flexible, and most functional SDR software I've found so far.

I installed it on Debian 13 and I'm currently using three RSP1 units from AliExpress and one generic RTL-SDR. It's still under testing in the city, but I plan to install it at my farm as well.

Many thanks to everyone involved in the project.

Last post by Bas ON5HB - 05 Jan 2026, 15:27
Hi Steven,

When you set the BW other then the 300-3000 default for SSB, like mine 100-2800, the starting BW isn't 2.70 but 1.35, exact 1/2 of it.
When you switch LSB/USB to correct it, it's not 2.70 but 2.75.

Can you please look at my server, then you see it happening.

Steven has implemented a squelch [enable / disable] for the configs in the next release.
