Re: Slow down the waterfall


Edouard Griffiths
 

The rule is that the waterfall moves at the actual speed given by sample rate and FFT size and the refresh rate is capped at 20 FPS.
However you can "slow down" using averaging: use fixed averaging or max if you want to trap short transients that could get skipped because of the refresh rate capping.
These are controls 5 and 6 here: https://github.com/f4exb/sdrangel/blob/master/sdrgui/readme.md#4-spectrum-display-control
