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.

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. 73" de i8CVS Domenico ----- Original Message ----- From: "J.D.
