Hi Norm,

Do you have a computer near the radio?

If so, Mike DK3WN has a little software solution to your question/problem!

Pick your satellite, move the slider...and off you go.

You'll at least be CLOSE....if you know the downlink of a station, use the program to see what the uplink will be. Of course, Doppler complicates things...move around a little for Doppler, etc.

Hi all!! How does one do this. It's not as easy as it sounds. Bearing in mind the fact that most birds are inverting, how do you do it manually, and then adjust for doppler.

Or answer someone calling cq? How do you find his spot? Not as easy as zero beating a cw station!! Thanks, Norm n3ykf _______________________________________________ Sent via AMSAT-BB@amsat.org.
