Adjusting Gain

The gain is used to adjust the sensitivity of the radar receiver. It can be used
to adjust the characteristics of the returns.
Gain adjustment is shown in the Gain bar graph. The white reference line on
the right side of the bar graph indicates the calibration reference point.
WARNING: Changing the gain in weather mode will cause precipitation
intensity to be displayed as a color not representative of the true intensity.
Remember to return the gain setting to : "Calibrated" for viewing the
actual intensity of precipitation.
NOTE: Gain can be adjusted in Weather mode on the GWX radars only.
