Right.  The signal now has a message on it, 90 second and 180 second
transmit periods (3/1 ratio was for hearing cw, we hardly need to maintain
that for visual work).  There are space times of both 90 and 180 seconds as
well, I will be confirming this later when I have time to make some notes.
The antenna current is ultra stable despite the weather so I am going to let
it run until further notice, 24 hours a day

If I have it right, from the best I can measure here I am better than + or -
.1 Hz at the moment, and Bill will email or phone if I start to move around
more than his ability to resolve frequencies hi.

Well 90 seconds looks good here....
