How long has it been since Loran stations used that area of the
spectrum? I remember hearing them on/about 1700-Khz at least 30-years
ago.

Been a good while. Over 20 years. Maybe late 70's???? I know they
were gone in the early 80's, as thats when I first started using 160m,
and I never had to deal with that awful racket. I sure remember it
from the 60's and maybe part of the 70's. Terrible noise...MK
