Very Low Frequency VLF Detector Circuit

Low frequencies predominantly cover our earths atmosphere. This range of frequency may be created by many different sources which may be quite unknown and strange, a VLF sensor equipment can be made to trace these frequencies for investigating the intriguing secrets hidden behind it. Steven Chiverton investigates. This is the vlf receiver circuit
Very Low Frequency VLF Detector Circuit - schematic

that ive upgraded and modified it senses ac fields lightening and even receives ship and aircraft radio to now this is what the circuit looks like without the upgrades and modifications, ive even used a gravity wave detector circuit added to it and also other experimental circuits This circuit looks very interesting, I guess it should start receiving signals at the infra sound levels, which may ideally indicate the many paranormal activities. Not very good at the technical explanation well ill give it a go the sensing signal booster on the far left hand side i bread boarded that to test it, to see if i can get more signal boost with it and the coil with its inductive nature pending on the amount of winds of thin wire and also the flux concentrator, this concentrate the em flux when a signal is induced into the coil and it increases sensitivity more, if you was to take it out the sensitivity and strength of signal would drop but then your in another mode as the circuit would still act as a lightening detector sensing lightening and the crackles will indicate that and the ac environment well it would sense that but at a lower response to it unless you re insert the flux concentrator core then the hum from ac mains will be increased a lot. now the vlf receiver section that will allow the signals from the sense head section to pass through, and very low frequency signals will pass through still but are filtered some more with...
