Title: When setting BW other then default, the BW is wrong at entering webgui.
Post by: Bas ON5HB on 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.

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.

Code Select
Changelog
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.
