Mike,

Communication is a different animal than navigation. You can
communicate without knowing where you are, you use navigation to find
out where you have been, are, and are going.

Receiving a signal 400 feet down would be quite a trick for a satellite
based transmitter running less than a watt to a vertical antenna! ELF
and VLF transmitters used to contact submerged subs seem to run around 2
Megawatts, hardly QRP!

Oh, and answering from 400 feet down would be a heck of a trick!
