Echo Stretch

Echo stretch is used to emphasise radar echo to increase detectability of targets. Position LOW emphasise both

noise and target level echoes while position HIGH emphasise only target level echoes.

Echo stretch HIGH.

Echo stretch OFF.

Improperly set radar Gain, Sea clutter filter or Interference reject could lead to an overload situation, in which

you see visual distortion such as above in your screen. Then check, if you have red text Overload, and adjust gain

or sea clutter filter and set Interference reject in High position.
