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? -- Paul Nicholson --
