No decode so far but that's no surprise.  I need to find the
right settings for this frequency: calibrating the E and H
rx phase and finding the best pre-blanker filter settings.

The filter settings become more critical down here because
some mains harmonics start to appear in the pass band.

Is it possible to send a few hours of carrier?
