    Here is a simple VLF receiver. I don’t know how well it works because I don’t go out into the middle of no where very often. You haft to be about 15 km from any power lines or well traveled road. The best time to listen is at twilight or night time. For the JFET I use a NTE451. VLF listening is a new hobby of mine. A 10’ antenna is about best. __ \|/ |.......................low current |...........................JFET | 47pF...........|------>>- |-| |--|---|->|.........amp. | 47pF|.....\...|--|..|->>- |-| |--|4M /.......|..| | 47pF|.....\.......|..| |-| |--|..../.......|..| | 47pF..... \.......|..| |-| |----|-------|--| (I hade to use .s so it wold work.
