0.2.8 - 2026-01-07
Fixed

    SSB (USB/LSB) mode switching no longer shifts the displayed tuned frequency due to passband quantization.
    SSB bandwidth readout no longer jumps when toggling between USB and LSB.


Sorry, it still does. Maybe not in I/Q mode but the RX888 Real mode is still jumping.
Also wrong BW when entering the GUI, 2.75Khz instead of 2.70.

Hi all,

If you downloaded Nova from github with 'git clone' command, updating is simple.
Here is a simple script to do it for you.

compile.sh (chmod +x) after you made it:

git pull

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

cd frontend

npm ci

npm run build

cd ..

exit



That's it.

BTW, I do run the compiling in a seperate directory and only copy dist and binary to the RUN directory, so I make sure nothing is overwritten.

Sure, following the configuration file receivers.json:

  "receivers": [
    {
      "id": "rx0",
      "input": {
        "accelerator": "none",

Hello!

I ask the developer to enable a dark version of https://sdr-list.xyz.

The transition from the pleasantly dark NovaSDR to the
completely white https://sdr-list.xyz is a shock to my old eyes.

I don't know what other colleagues think about it.

Best regards,
Darko, 9a7aof

Bug is still there. Running 0.2.7

It may help others if you posted your receivers.json to show how you did this.

Ok found the additional setting:

> Add SoapySDR device settings? (key=value) Yes
> Setting key (blank to finish) direct_samp
> Setting value 2

Hi there,

I'm testing NovaSDR with RTL-SDR v3 dongle. Everything works well in NORMAL MODE (VHF/UHF) but I don't know hot to configure DIRECT SAMPLING MODE for HF.

Any advise? Thanks.

QuoteMake the server just check if they are in any RXx limits, when not, don't show at all.

Works fine in v0.2.7

My root crontab script for automatic start NovaSDR after reboot
#---------------------------------------------------------
@reboot su darko -c   /home/darko/bin/nova &
#---------------------------------------------------------
40 06 * * * su darko -c   /home/darko/bin/nova &
#---------------------------------------------------------

and script in my bin directory
#!/bin/bash
cd /home/darko
/usr/bin/killall novasdr-server
/bin/sleep 6
/usr/bin/rtl_sdr -g 48 -p 36 -f 145000000 -s 2048000 - | /opt/novasdr/novasdr-server -c config/config.json -r config/receivers.json

It work in background, log I see with
tail -f logs/novasdr.2026-01-07
Thanks!

This way anybody can put there what they want.
