Well, that's a relief, that there's another Sept Isles bay than the one I
got to to know in Brittany. I would hate to think of that tranquil Baie de
Sept Isles as the spot where such monsters transshipped their coal! I
suppose, around the world, there must be quite a few bays that have seven
islands. It was the French name, and Bruce's reference to a French carrier
vessel that seemed to confirm it. But I should have thought of Canada.

Just about gone, yes. I found them useful, in their day. In UK waters the
transmitters were taken over to provide the reference transmissions for
differential GPS, when that was needed, in the days before "selective
availabiity" was ended. I think a few aero beacons may remain around the
coast but the sequential marine DF chains have gone. They were most useful
when at a port entrance, so you could home in on them. Position by cross
bearings was always somewhat dodgy.

If we had no wind, and chose to motor, I would find myself in communion with
the DF receiver up in the forepeak, with the spare sails, to get away from
the noise and vibration and get a clear(ish) null. The trouble then was,
with me at one end of the boat, and my wife on the helm at the other, there
was no way I could ask her about the identifying signals, as she was the
only one that knew Morse.
