After doing some research,
I just discovered that it is fairly easy for me to make an FSK modem.
FSK seems to use 2 frequencies for transmission. one for mark, and one for space. (presumably logic 1, and logic 0).
I do have some questions.
1. Does FSK use only 2 frequencies and half-duplex transmission, or does it use 4 and full-duplex transmission?
2. What are (or how do I calculate) each of the frequencies involved with FSK?
Once those are answered, maybe I can make a modem and possibly connect here with it.
