So that's the freq! For the life of me, I got zillions of hits, but none
talked about the frequency. I only remember the old 1.8 MHz. (or whatever)
Loran system.

Hey there Steve, and the group,

If you want some good reading on the operation of the 100khz Loran-C,
download the manual for the rayplot 700L from Raymarine.com They cover
the 'How it works' department real well. No schematics however. I have
a small battery operated scuba tow unit good for bay, or lake use. It has
no compass due to the very large motor magnets. I was thinking of building
my small portable Loran-C receiver into a waterproof box, and towing an
insulated antenna wire of perhaps 10 feet length behind me. But I was unsure
how deep I could dive, and still have a useable signal. I have a 700L for
land use in my mobile. It works great!

Is the 100khz Loran C signal useable while submerged? Do to it's
long wave nature, does it penetrate the surface to any depth beyond
a few feet?
