Re: Old (without PC) tracking ?

Yes. This workd fine and believe it or not after reading this I checked
and found I still have mine. There is also an overlay for the phase III

in fact I think I still have my AO-10. If you can find one, they worred

Somewhere we use to get approximate pass over times for an area
and then you can base your future pass times for a few days on those
times and the chart.
