Interference rejector
This control is similar to the interference rejector on echo sounders and radars. It is

tions. Set it so that noise is just eliminated. Do not use an unnecessarily high setting
since it may also reject small wanted echoes.

Shift1] well apart from [Freq Shift2] to better suppress sidelobes.
