v1.391,392,393,394: New noise blanker and filters
From the CHANGE_LOG file:
v1.391 May 23, 2020 User interface changes: SAL, SAU mode passband image will only show single sideband (just like LSB, USB). Ctrl/alt-click on mode button toggles modes backwards (most useful with SAM modes). Same works with keyboard shortcuts, e.g. ctrl/alt-A toggles SAM modes backwards. Noise blankers and filters: Reworked the audio tab user interface to support multiple blanker/filter algorithms. New algorithms planned but not yet available are greyed-out in the menus. From Warren Pratt's wdsp package added the variable-leak LMS algorithm. Merged Howard Su's RPi changes. Note: RPi is not officially supported by KiwiSDR. Ask for help on the KiwiSDR forum: http://forum.kiwisdr.com/discussion/1986/port-kiwisdr-to-raspberrypi-3b Bug fixes: Audio recordings made in SAS (synchronous AM stereo) mode now work. Fixed problem with ITU region 2 Kiwis and shift-clicking waterfall in 75/80m band segment. from lazywalker: fixed problems with frequency memory and reload value when transverter offset used.
