[amsat-bb] Doppler Curves ?

[John Heath]

hi guys,
 
in the "olden days" a satellites TCA could be determined by using pencil and graph paper and plotting time v frequency.
 
Is there a modern and more elegant way of doing it with signal anaysis software like Spectravue, Spectran or similar.
Need it for an education outreach project and I just know that graph paper and pencils will not be cool.
