Franks interesting bit about reception in NC refers to 770khz - a long way
from 136 - which in turn is a long way from the  navy/submarine freqs.
(anyone know what the navy freqs. are ? )

From the site of Renato Romero ( http://www.vlf.it/submarine/sbmarine.html ) :
----
Signals directed to atomic submarines in immersion. USA and Russia transmit in the ELF band generating a slow binary code. Frequencies are 76 Hz for the U.S. system and 82 Hz in the Russian system; the E.R.P. (Effective Radiated Power) is small, probably a few Watts, but signals are receivable around the world.

Note : they are 76 and 82 Hertz, not kilohertz...
