Received here -

 900m Ant:  T2019-03-31_13:58,+10m: 1.07fT S/N -10.4dB/1Hz

 1130m Ant: T2019-03-31_14:12,+10m: 1.30fT S/N -7.6dB/1Hz

The signal strength hasn't increased as much as the area has
increased.  So maybe the ground return current has remained
at the same depth.  Then the signal would increase as by 1130/900
which is close to what I see here.

Can you compare amplitude and not S/N?
