AGC Decay, Fast
AGC-F decay rate. A higher value results in a shorter decay time.
AGC Decay, Slow
AGC-S decay rate. A lower value results in longer decay time.
AGC Hold Time
Sets the hold time (applies only to slow AGC). Non-zero hold times are
often preferred by SSB operators.
AGC Noise Pulse Reject
When this parameter is ON, the DSP will suppress large, periodic noise
bursts typical of electrical appliance turn on/off, etc., preventing
saturation of AGC and consequent long recovery time. However, when
continuous pulse noise is present, the noise blanker (NB) will be much
more effective. Use the lowest effective NB setting to avoid
intermodulation.
AGC Slope
Sets the slope of AGC. A higher value keeps the audio level constant
over a wider signal amplitude range. A lower value allows for greater
variance. AGC slope settings can be combined with threshold settings
to achieve the desired overall AGC profile (see AGC Threshold, below).
AGC Threshold
Sets the signal level where AGC action begins.
A low threshold (4 or 5) combined with a high slope (15) will result in
maximum compression of dynamic range. This in turn can minimize
the need to adjust AF gain.
Some operators prefer the opposite effect. A high threshold (6 to 8)
combined with a low slope (10 to 12) will minimize the application of
AGC, imparting more "presence" to signals.
