Hang on, Reg - didn't you spend your career working on VLF cables that
went under the ocean?


How did you keep the water out of the slotted cable? And how far did you
have to swim between Vmax and Vmin?

===============================

Water can be kept out of slotted cables by the ship's radio operator who
never has anything else to do. We used to toss him overboard with a ladle
and pump. On occasions we used the ship's doctor when he wasn't propping up
the bar boozing duty-free scotch.

Didn't have to swim anywhere. The propagation velocity is so low at ELF in
sea water it is necessary only to sit on a stool in a diving suit and wait
for the max's and min's to pass by.
