70% to pass

In order to insure that the racon signal is visible on your 3 cm radar, the _______________.

A gain control should be turned to maximum
B rain clutter control should be off but, if necessary, may be on low
C 10 cm radar should be placed on standby or turned off
D radar should be stabilized, head up
AI Explanation

The correct answer is B) rain clutter control should be off but, if necessary, may be on low. The racon (radar beacon) signal is designed to be detected on 3 cm radar. To ensure the racon signal is visible on the 3 cm radar, the rain clutter control should be turned off or set to a low setting. This allows the racon signal to be clearly displayed without interference from rain or sea clutter. The other options are incorrect because they do not directly address the need to minimize clutter on the 3 cm radar to detect the racon signal.
