Thanks to Lyle and Roger ( RM ) I have two captures from that central area
(Duluth and Aitkin )  showing the exact same lines, as you would expect. It
is interesting to note that only these fellows have a line that is almost on
top of the 137780.4 frequency - quite unlike any of the other captures from
the Northeast, Southeast, and South.  Based on this observation, I think it
would be a better choice of frequencies if I were to move down approximately
0.4 Hz, and try to end up on 780.0.

Lyle's capture at 1100CST ( noon in London ) shows very clear Loran lines,
and Roger's capture (taken at midnight ) is showing other weaker lines - due
to longer propagation, as Lyle mentioned.

Using the captures from different directions from this Great Lakes area,
along with the very interesting and valuable list that was provided by
Messrs Andrews and Davis will allow us to move about and find those "clear
channel" areas between the lines - even in the most "Loran polluted" areas.
Thanks to all.
