Hello Ian and all,
Perhaps you missed my bulls on OMEGA and a few others saying it was
discontinued. The navigation end of it was outdated and the messaging
system impractical for alert traffic, which BTW was one way to the subs.
Now it's done with satellites, the subs raising a tethered buoy to the
surface. Any method of alerting the sub to an incoming message is
classified of course.
As for the propagation, it's not ground wave which travels along the
boundary layer of earth and sky, but earth wave which travels therough
the Earth itself. That's why the antennas were buried. Perhaps that
fellow was thinking of GWEN, Ground Wave Emergency Network, which uses a
variety of above ground antennas tailored to the frequency in use. There
is one in southern NJ I have seen and the antenna is a surprisingly short
tower. Don't ask how they get away with that one! It is a hardened site
intended to remain in operation after a nuclear strike being all but
ground wave would be knocked out by ionospheric disturbances.
