Doppler velocities of 150-km echoes represents the vertical ExB drift velocities at F region altitudes. 150-km observations represent and excelent mean of monitoring the electric fields at equatorial latitudes. Low power observations of 150-km echoes using the JULIA system have been carried out almost continuosly since August 2001 at Jicamarca [e.g., Anderson et al., 2004]. Most of the observations have been done pointing perpendiculat to the magnetic fiel (B) in the magnetic meridian, allowing the measurement of the vertical component of the ExB drift.
