For lunar echoes, _WSJT_ generates short fixed-frequency transmissions
that alternate with reception intervals at the appropriate
Doppler-shifted frequency. With *Split Operation* set to *Rig* or
*Fake It* on the *Settings | Radio* tab, check *Doppler tracking* and
*Own Echo* on the Astronomical Data window. Point your antenna at the
Moon and click *Enable Tx* on the main window to start a sequence of
