Listening
To listen to SACRED if it had made orbit, a person would have needed the following:
- The keplerian elements, in order to know where the satellite is pointed.
- A radio capable of operating on 436.870 MHz, which will change with doppler shifting.
- A 1200 baud AFSK modem, preferably a very low-end, that does no modulation on its own. Cubesat Groundstation uses a custom-built hardware modem, and possibly a software modem (using the sound card as an Analog-to-Digital converter).
- The UA Cubesat GS software would help, however, it is not currently available to the public.
- A good antenna system, the design of the antennas is not optimal.

Famous quotes containing the word listening:
“Listening to someone talk isn’t at all like listening to their words played over on a machine. What you hear when you have a face before you is never what you hear when you have before you a winding tape.”
—Oriana Fallaci (b. 1930)
“The democratic youth ... lives along day by day, gratifying the desire that occurs to him, at one time drinking and listening to the flute, at another downing water and reducing, now practising gymnastic, and again idling and neglecting everything; and sometimes spending his time as though he were occupied in philosophy.”
—Plato (c. 427–347 B.C.)
“Opera once was an important social instrument—especially in Italy. With Rossini and Verdi people were listening to opera together and having the same catharsis with the same story, the same moral dilemmas. They were holding hands in the darkness. That has gone. Now perhaps they are holding hands watching television.”
—Luciano Berio (b. 1925)
