Hello VLF.
Just a experience message !
 
It seems that there is somewhere a perfect = setting in=20 "Width of FFT-bin", but where ?
 
Measurements below in SL by noise and = peak:
 
47 uHz - DJ8WX =3D noise -157 / Signal -134 = (-23dB above=20 noise)
16 uHz - DJ8WX =3D noise -158 / Signal -136 = (-22dB above=20 noise)
 
Signal vs. Noise level is -1dB better at 47 = uHz in=20 relation to the 16 uHz window.
 
I expected, based on the trend between = 424 uHz, 238=20 uHz and 47 uHz, a better S/N ratio at 16 uHz.
 
Now testing 105 uHz :-)
 
73's, Peter - PA1SDB
