transmitter frequency. Long story). Now that analog TV has gone
away, so have these signals.

anyone has a manual for this version or a pointer to it I'd really
appreciate it. I have the manual for the "D" version but apparently this
is considerably different.
Thanks in advance for any help!

transmission line, for example. GPS has made it possible to
measure this accurately even over long distances using purpose-built
instruments. Google "Phasor Measurement Units" got more information.

Jim,
IIRC, the IBM 360 mod 91 was one that used a MG set. I think it also
required chilled distilled water for cooling. Those were indeed the
days of "Big Iron".

If you are at IFCS in New Orleans and want to use a repeater, my first
recommendation would be the 444.200 machine if you have 70 cm and
alternatively the 146.86 2-meter machine.

If you go to the amasci.com link they have a CD with all of the Amateur
Scientist columns in it. It was amazing what some of those guys did way
back then in a garage or basement.

As the engineer quoted in the article says, Iran is not Afghanistan or
Pakistan. Unfortunately Americans aren't very good in geography or history and
we tend to lump everybody in that part of the world together, and so forget
that Iran was once called Persia and the Persian Empire at one t
Folks,
Actually, the USGS goes around measuring the local gravitational constant
in various places. There was a gravimeter set up in the basement of one of the
local universities a few years back doing just that. And some time ago, the
U.S. spent a fair amount of time, money and effort (
Sal,
It's also a relatively simple mod to rearrange things in the 59309A to
accept the 1 pps input from a GPSDO. I no longer have my unit for the exact
reference, but it simply involved lifting one side of a capacitor and
connecting it to the external DC BNC on the back. Feed in the 1 p
Hi, Scott,
They track because most of Arkansas is part of the Eastern Interconnection
and the transmission systems are tied together through that. The general shape
follows the loading of the system; that is, as the load increases throughout
the day the alternators slip behind; as it decr
see how far off things
get, not to mention see any large disturbances. There might be some
interesting viewing there this summer. There is also more info available
on their "Gridwise" program.

I think the book referred to is The Scientific American Book
of Projects for the Amateur Scientist by C. L. Stong (no "r' in Stong)
I too used to just read it - great book. It's a collection of some of "The
Amateur Scientist" columns by Stong from Scientific American
magazine. Unfortunately it'

And IIRC, DEC defined 1/60 second as a "jiffy"; it was also used to do task
switching on the time-sharing systems (e.g., PDP-10 AKA DECsystem-10).
