[amsat-bb] analog the hard way

[Ron VE8RT]

Thanks Jim,

   I started off in the early 90's with a Ten Tec 2510 :-)  I'm using
the same Helix antenna that I've dragged through every move since.

   From what I've read the practice has changed a little, we aim for a
constant frequency at the transponder input.

   The parts, for the most part, are here to make an Arduino controller
for the rotator.  The Doppler correction is now manageable, as long as
I enter the right figures into the GPredict calculator.

   I'll poke away at this, and getting some current QSL cards printed
(I do that and paper log books).

   Ron
