NOTE: it is more accurate and visually simple to minimize alternate set of transponder signals rather than maximizing the
transponder of interest.

Step 9 of 9: With all 24 transponder signals of approximately equal amplitude appearing on the Spectrum
Analyzer screen, determine the specific antenna system and satellite parameters. Rotate the feed assembly as
required until the appropriate (odd or even) transponder signals have been maximized.
