Overload Detector DAC Adjustment
The overload detector is in the first IF in the A20 Low Band. It is used as a warning when
a high input level outside the viewing span is compressing the first mixer. It can also be
used as a diagnostic tool.
This adjustment should be performed after replacing the A20 assembly.
