what the bit rate is. I don't see how they can transmit more than 2 or 3
characters a second.

My neighbors accused me of trying to receive those signals when I hung up a
160 meter delta loop around the yard but it is only 529 feet around. 45 Hz
requires 22,000 feet. They really would get upset about that! :-)

Does this mean our subs are 22,000 feet long? I knew they were getting
pretty big, but ...

OK, I suppose they can tow a long wire, but still 22000 feet seems a bit
much.

With a less than ideal antenna you will get less signal. So what?

We motored right up to the dock where the sign says, "Do not approach
within 300 feet." With typical government common sense, the type size is
such that the sign can't be read until you are within 100 feet.

I was rooting around in the cabin, looking for I forget what. when the
crewmqn closely approached the bouy marked hazard, drowned trees.
The fool chewed my prop somewhat. What is it about warning bouys that
makes prople snuggle up to them.

The fine print.

I never heard of or observed such a tendency. This wasn't a buoy but a
large dock clearly intended to accomodate large supply vessels so there
wasn't any navigational concern with less than 5 feet of draft. 300 feet is
just the DOD's idea of security. If they were really serious about it, they
would put out those yellow buoys that are starting to appear in some places.
The towers go right up to the edge of a working harbor on the other side so
keeping people at a distance is kind of pointless.
