Terminal Node Controller

A Terminal Node Controller (TNC) is a device used in packet radio. The TNC is analogous to a MODEM in wired communications. The TNC converts analog audio signals that have been received over the radio into digital bytes to be sent to a computer, and also converts digital bytes from the computer into analog audio signals that can be transmitted over radio.

[| Terrestrial Amateur Radio Packet Network (TARPN) TNCpi] offers a TNC kit that connects to a Raspberry Pi computer.
