- Added a preset update button (the diskette with the yellow corner) to be able to save the current settings on an existing preset
- Added variable decimation in log2 increments from 2^0=1 to 2^4=16 allowing to see the full 2048 kHz of spectrum if so you wish
- Better handling of rtlsdr GUI display when settings change (initial load, load of presets)
- Added display and precise control of the shift frequency from center frequency of the NFM receivers.
- Removed useless spectrum visualizer in NFM receivers. Created a null sink class to fit corresponding parameter in NFMDemod class constructor.
=====
To Do
=====
- Display center frequency of the receiver in scope. Presently there is no way to set the frequency precisely
- AM demod. What about the air band?!
- Add the possibility to change the brightness and/or color of the grid. Sometimes it is barely visible yet useful
- Possibility to completely undock the receiver in a separate window. Useful when there are many receivers
