Install problems / RTL-SDR direct sampling mode
Last post by iw7dle - 07 Jan 2026, 09:50
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!

Bands.json? ;D

This way anybody can put there what they want.
Make the server just check if they are in any RXx limits, when not, don't show at all.

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. :)

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!
