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:
“In this our talking America, we are ruined by our good nature and listening on all sides. This compliance takes away the power of being greatly useful.”
—Ralph Waldo Emerson (1803–1882)
“While yet a boy I sought for ghosts, and sped
Through many a listening chamber, cave and ruin,
And starlight wood, with fearful steps pursuing
Hopes of high talk with the departed dead.”
—Percy Bysshe Shelley (1792–1822)
“Sentences and paragraphs. Sentences are not emotional but paragraphs are. I can say that as often as I like and it always remains as it is, something that is. I said I found this out first in listening to Basket my dog drinking. And anybody listening to any dog’s drinking will see what I mean.”
—Gertrude Stein (1874–1946)
