    I need to send bytes to my remote control drone I am planning on building. How can I make two tranceivers that send numerical data, not sound to each other? I would like to send the data over fm if I could do that easily.

    Could I just supply power to an oscillator when a signal is received and use the oscillator to count how long it takes to receive another signal? If the timer is 1, then a one was received and if it was 2, a 0 was received.

    How can I detect any radio wave at any frequency? Can I just connect a long antenna to the base of a transistor?

    At any frequency, yes. But it would be more effective to have a tuned circuit in order to detect a specific frequency.

    What resistor value should I use for the antenna? Would 1 ohm work? Also, how accurate would a lc circuit be at choosing radio waves at a certain frequency?
