I loved using the manuel method! I even went so far as to derive the orbit equations myself. But it was exciting when the tracking software for the Timex Z-81. Still have have one in the shack.

Hi Smith, N4VIL
Early in 1972 I was receiving by regular post the 2 Line Orbital Data from Goddard to be used for the meteorological satellites ESSA-8, NIMBUS and TIROS
For traching I used as well the azimuthal map of the earth with a foot print transparent overly and a revolving satellite orbital path.
Yes...no computers at all in the Ham shack at that time but manual tracking using a map a pencil and a clock was a beginning very useful and exciting.

Rich,
I remember receiving the two line elements from Goddard in the
mid-eighties.
I was just getting into amateur radio, but was only using the data to predict visual sightings of the shuttle and satellites. I believe the list
I
received was a generic for visable satellites. I used the data to manually plot an orbital track with grease pencil on a piece of acetate, using it
as
an overlay on a map of the earth. I'm sure there's probably more than a
few
people here that did the same 'back in the day'. Aren't computers great!
