Here is a customised version of SDR++ (https://github.com/AlexandreRouma/SDRPlusPlus) for my needs.
Additional features:
- When clicking with right mouse button on FFT spectrum, toggles the Hold line (checkbox management to be added);
- Bookmarks manager (https://github.com/darauble/bookmark_manager) in place of the standard Frequency Manager;
- SSB (USB and LSB) max bandwidth 24 kHz in place of 12 kHz (from https://github.com/ericek111/SDRPlusPlus/tree/om2lt);
- Sliders operating with mouse wheel (from https://github.com/qrp73/SDRPP/);
Key bindings: With respect to the original hotkeys (https://github.com/AlexandreRouma/SDRPlusPlus/wiki/UI-Controls#main-ui):
- F6: Toggle waterfall.
- F5: Start/Stop.
