Suggestion to tweak default bandwidth settings [fixed in v1.454]
-
v1.456,458,459
Short version: Old behavior restored so external apps, including those using kiwiclient et al, should work as before. But Kiwi web interface uses new changes as described below.
v1.459 May 23, 2021
Waterfall / spectrum:
Fixed the CIC compensation added to the last release.
Added waterfall interpolation URL parameter "wfi=N" e.g. kiwi:8073/?spec&wfi=13
Also available as an API parameter on the waterfall web socket: "SET interp=N"
Value N below. Add 10 to enable the CIC filter compensation.
The value below answers the question: "What to do when multiple FFT values
contribute to a single waterfall/spectrum pixel bin". In most cases the FFT
is larger than the 1024 display pixels of the waterfall (or external application).
0 take max (old and continuing server default for kiwiclient, external apps etc.)
1 take min
2 take last
3 do drop sampling
4 take cumulative moving average of values
...
13 drop sampling + CIC compensation (new Kiwi browser interface default)

v1.457,458 May 21, 2021
Waterfall / spectrum:
Fixed low-level post-FFT artifacts spotted by Marco's SuperSDR app. Thanks Marco!
Added CIC filter compensation to better level spectrum at top end.
FAX extension:
Added GM-11F Sevastopol 7090.9 kHz per fabrys on Kiwi forum. Thanks fabrys!

From the CHANGE_LOG file:
v1.455,456 May 19, 2021
Admin page
Config tab: Added button to reset passband fields to default values.
Connect tab: Improved proxy setup UI.
Right-click menu: Added "snap to nearest" mode. Setting is remembered/restored per Kiwi
visited just like freq/mode etc. Waterfall cursor differs when snap mode active.
When snap is active the freq step keys (j/i, left/right arrow keys) are modified so
the ctrl/alt-key steps the smallest amount and the unmodified key steps the same
amount as the snap (e.g. 9/10 kHz on MW). Usually the unmodified key step the
smallest amount.
Changes to more easily support general (even non-SDR) FPGA development.

Preset HPF setting [fixed in v1.454]
v1.453,454 May 14, 2021
Added default passband adjustment to admin page, config tab.
As each passband parameter field is changed (low, high, center, width) the other
fields will be automatically adjusted. So if you know you want a USB filter
with a low frequency of 300 Hz that is 3300 Hz wide just enter those two fields
and the high and width values will be derived. An error message will appear if
you attempt to define an invalid passband.
The former "CW offset" field has been removed. To set your desired CW offset
simply set the default passband center frequency of the CW/CWN mode passbands
to the offset value. E.g. If you want to hear a 1000 Hz tone in the CW modes
set the passbands to have a 1000 HZ center.
After the passband is changed on the admin page, existing user connections will have
to reload the page to get the new passband values.
