Go find Radio-Electronics magazine for 1983, and read the five(?)
articles by Ralph Burhans about receiving VLF.
I ran across one article he wrote, in PDF format, but couldn't
locate the articles. Have you seen them posted anywhere?
Also, Dr. Barry Ornitz was kind enough to send me a PDF file
describing two books available from the ARRL online store at
http://www.arrl.org/:
Mike Dennison and Jim Moritz: LF Today
Peter Dodd: The Low Frequency Expermenter's Handbook
He also took the time to offer a description of why a JFET input
matches a high impedance. The words seem to fit together, but I'm
still working on downconverting it to a frequency low enough for my
brain to accept. grin!
