Re: [IRCA] SDR-Console and the Perseus SDR Volume Levels

[Chuck Hutton <charlesh3@xxxxxxx>]

Les:
 
I'll bet some things are mixed up here.
 
There's no sampling rate of 950 regardless of the unit you meant (samples, kilosamples, etc).
Did you mean to set the center frequency to 950 kHz? That's a common choice to record 1.6 MHZ (not 1.75 MHZ) of spectrum, thereby covering 150 kHz to 1750 kHz.
 
Whatever sampling rate and center frequency you use has really no effect at all on "quality", although I am not sure what that means to you.
