E-field VLF natural radio receiver


My design of the E-field VLF receiver is shown above.

The LDRs are binded with the LEDs using thermal shrink tube, like shown above. A suitable monitor amplifier is shown below. The amplifier input is connected to point C of the schematic, using an appropriate potentiometer in voltage divider configuration, to set the volume of the monitor. The output of the amplifier is connected to a set of headphones and the volume is very much adequate.
