Ask Dr. SETI ®
I am a Radio Telescope Operator at the 12m ALMA Prototype Antenna on Kitt Peak AZ. We get tours. One question referenced the movie Contact. I just finished the book and cannot verify or validate the reference on page 66 and page 72 to 9.24176684 GHz. Page 68 says this frequency is "near the minimum in the galactic radio noise background. It's the right kind of frequency for anyone who wants to be heard over a distance."
The Doctor Responds:
Robert, first of all, remember that Prof. Sagan's novel was fiction. So, he was free to make up whatever frequency he wanted. The quiet microwave window is quite broad (about 1 to 10 GHz), and any frequency within that range is just as likely (or unlikely) as any other.
