	Not so;

	Designs for H-field antennas for LORAN and GPS exist, and
have been prototyped.

	eLORAN receivers perform on the order of unassisted GPS,
and combined receivers (eLORAN+GPS) beat the accuracy of either.

	The problem with the -C shutdown is it means they having
nearly finished the upgrades, will never run the new system.
It's going to cost more to tear it down than finish the modernization.

	Cheers,
