I wonder if it is possible to use radio astronomy. You'd have to find
an object that doesn't require a very large antenna to acquire its
signal.
I understand that optical tracking of a star crossing a hair is more
precise than the peak of a radio signal, but perhaps modern signal

resolution is to use centroid timing techniques. The input pulse is
converted to a short pulse using a delay line timed monostable then
the resultant pulse is low pass filtered by a discrete component RLC
I talked to the Agilent Library, and they said that
if I donate these manuals, they will be stored but
not scanned at this time. I thought I would ask
here if there is any interest in any of these manuals.
Perhaps I can scan a few myself if there is sufficient
interest.

This sounds like an interesting project. I've been looking for something
to do with the Meade 4455D telescope I just got. (D=114m F=910, f/8)

Especially when you consider that HP at one time had manuals
for everything they made... Then they stored them and lost them.

Data Delay Devices quote 1-2% typical variation in delay for their all
silicon delay lines over the -40 to + 85C operating temperature range.
These devices have built in temperature compensation.
They claim a residual tempco of 200ppm/K
Maxim/Dallas don't specify this parameter for their
Passive delay line has a much lower tempco than active delay lines.
Typical tempco is 100ppm/K.
Just add you own active devices and line termination.
