[hpsdr] NOISE FLOOR

[Tony Hagen]

Surprisingly, the Noise floor increases if we increase the ATTENUATOR SETTING next to AGC Level on screen. Till 30 the NOISE FLOOR increases TO an extent and when the setting is above 30 a relay operates and the noise floor increases Appreciably high.

When I am using the Attenuator the noise floor should decrease rather than increasing – ANY IDEA? will be a great help
