Thanks to ALL who responded with quick and cogent findings... It has seemed for a time that with the receiver AGC and NBs OFF that I generally can see a deeper signal, depending on conditions... The
I seem to get best results while trying to pull signals out of the noise when the AGC of the receiver is OFF as well as the Noise Blanker and Noise reduction features being OFF... Do you concur?? Als
What is the expected ambient noise say @ 600M one should expect?? I then connected to the outside antenna with no external pre-amp or any non linear device and saw -117 dbm of noise across 10 khz. wi
It all depends on your resolution bandwith which you don't specify. Pnoise = kTB With my SDR-IQ set to 190kHz span and 131072 point FFT, resolution bandwidth = 1.5Hz and Rx set to +10dB gain to get t

The effect of AGC is even worse than amplitude modulation, it can add a non linear element to the signal processing. The amplitude of the receiver output is proportional to the input power multiplied
