As an amateur radio operator for 25+ years, hams have always had to take a back seat to Loran on 1.8 to 2.0 mHz. Hams were to avoid frequencies used by Loran transmissions and gladly did so. As for mariners, even most cruise ship captains will go out and look at the stars. Loran was a nice back-up for their already long experience with navigation by the sun during the day and stars at night.

Loran for all the help you have given over the years.
Now, hams have a tad more elbow space on 160m.
