b.
Orient the receiving antenna in a direction that is expected to yield the lowest signal level that the receiver
is likely to encounter.
c.
Activate AGC Zero under this condition by clicking on the Zero AGC button.
The AGC output voltage is set to zero volts DC at a time when the receiver input is at its minimum value. This
process ensures that the AGC output voltage will not cross through zero volts DC under normal operation.
To confirm AGC Zero, view the Monitor screen Signal Strength bar graph. If AGC is not zero, the graph is grey and
there is no AGC Zero value displayed, as shown in Figure 269. When AGC is zero, the bar graph is not grey and the
AGC Zero value is displayed, as shown in Figure 270.
