[Elecraft] K3S ELF 10KHz

[Mel Farrer]

Doug,
Didn't the Navy use those frequencies to communicate with the submarines?  I remember something about 30 KHz and an Atlantic Island and something Washington with a setup???
Long in the tooth ham!

Way back in ancient times I worked at a research lab where we had a LOT of receivers tuned to all the signals we could find below 60 kHz.  I think the lowest was 13.x.  There was an 18.x and 24.x etc. etc.  We were only interested in signal strengths and plotted each signal on strip chart recorders, 24x7.  It was very interesting working at those frequencies.  (This was all part of a solar observatory project.)

So, I guess *that* would qualify as a reason to listen to this stuff..
