HD 1420 VLF converter

[Domenic M. Mallozzi]

The Navy ran (and may still run) a facililty which ran something like a
megawatt on 76 Hz (thats right Hz) from Clam Lake WI. There was an article on
it in Popular Communications a few years ago. It did not used buried antennas
as was originally planned (when it was called Project Sanguine and Seafarer) .
But the antennas were something like 13 miles long.

Those frequencies are really unbelieveable. I went to school at the University
of RI and they had a US government sponsored unclassified research project
that among other things using a site in Germany and another site could spot
thunderstorms worldwide. It did it by off-line triangulation (20 years ago
computing wasn't what it is today). Receiving at those frequencies has some
real strange problems.

Dom
