5
Q
When MAP is selected ___
A
- Selection is used for ground mapping.
- Aerial will need to be tilted down
- Swept gain deactivated
6
Q
When RANGE is selected ___
A
- ## Switches Tx/Rx power and timebase and allows the maximum range to be selected
7
Q
When TILT is selected ___
A

Outline how swept gain works
A
Immediately after transmitting, the receive gain is set very low and increased as time passes. For very weak signals which have taken a long time to return, the receive gain will be at maximum gain.
