4.7 - Adjusting AGC
AGC, or Automatic Gain Control, is a radio feature that limits the sensitivity of the receiver according to how strong the received signal is. DCY (Decay) controls how fast the AGC turns the gain up; the value is milliseconds, so 1000 is the same as one second. Gain reduction is instantaneous, which in turn means you will never experience audio clipping or internal signal chain overload from sudden strong signals. This is possible because SdrDx analyzes and processes signals before it provides the audio derived from those signals to your ears.
DCY can work in a linear mode, or a logarithmic mode where the precision is higher towards the faster AGC end of the slider. You set the mode with (decay/log/linear.) Try on and off, use the mode you prefer.

4.8 - Adjusting I/R
I/R (Intercept/RF-Gain) sets the maximum gain the receiver will use. The most gain is available with the slider at the far left. You can see the current gain by observing the S-Meter models that provide AGC display.
