Hello VLF.
Just a experience message !
 
It seems that there is somewhere a perfect setting in "Width of FFT-bin", but where ?
 
Measurements below in SL by noise and peak:
 
47 uHz - DJ8WX = noise -157 / Signal -134 (-23dB above noise)
16 uHz - DJ8WX = noise -158 / Signal -136 (-22dB above noise)
 
Signal vs. Noise level is -1dB better at 47 uHz in relation to the 16 uHz window.
 
I expected, based on the trend between 424 uHz, 238 uHz and 47 uHz, a better S/N ratio at 16 uHz.
 
Now testing 105 uHz :-)
 
73's, Peter - PA1SDB
