Hi,
I would like to make a survey of the noise floor of your rigs. I am not 
looking for any calculations for the noise density, just tell me your 
sound card resolution and what you see at the bottom of your frequency 
spectrum of the Powersdr or sdradio software. This is what I get:
Maker of rig: my own
Sound card:16 bits
Line at bottom of spectrum with radio off: -100dB
Line at bottom of spectrum with radio on: -65dB
Frank
