Yeah. It's a TLA (three-letter acronym). It means transistor-transistor
logic. It's how computers work. The logic signals (high and low)
correspond to voltages, typically +5v and 0v. Those are the digital
signals that get piped around computers, representing whatever
information you're processing. TTL basically says that a HIGH signal
equals +5v and a LOW signal equals 0v (or *very* close to it). You'd
need a chip (modulator) that converts this digital signal into an analog
(sound) signal for transmission over the radio, and then a demodulator
chip to convert the analog/sound signal back into TTL logic signals.
Whew!
