Thanks, Mike for your kind words of encouragement.  A comment, though:

Excellent. I feel that concentrating on this high ERP station will
provide a useful pattern.

DCF is an inland station, fairly far away from the ocean coast, with an unknown
(unknown to me, at least) antenna radiation launching angle.  The fact that it
can be heard throughout Europe (probably ground wave) does not necessarily mean
(to me) that it will cross the pond via multiple hops. We did hear France-Inter
(on 162) and Europe #1 as if they were local broadcast stations. France Inter
runs 2 MW, I understand. Has anyone yet established a comparison between those 2
MW with a 9 KHz bandwidth and  DCF's power with its bandwidth ?
