To ensure that the racon signal is visible on your 3 cm radar, which adjustment should be made?

To ensure that the racon signal is visible on your 3 cm radar, maintaining an appropriate level of clutter control is essential. Rain clutter control functions by filtering out unwanted signals that can obscure important information on the radar display. If rain clutter control is set too high, it may reduce the visibility of the racon signal, especially when it is relatively weak compared to background clutter. Having the rain clutter control either off or set to a low level allows for greater sensitivity to these signals, ensuring they are discernible against any surrounding noise.

In the context of radar usage, keeping rain clutter control low maximizes the radar's ability to detect return signals, which is critical for effectively identifying landmarks and navigation aids marked by racons.
