The three parts of a packet radio station work together as follows:
•
The transceiver : (1) sends and receives radio signals to and from your
antenna and (2) passes audio signals back and forth between itself and
the TNC.
•
The TNC (Terminal Node Controller): (1) translates audio signals into
digital information and vice versa, (2) performs a number of control and
information storage functions, and (3) communicates digitally with your
computer.
+ Multi-port TNCs (e.g., Kantronics KPC-9612 Plus) can support more
than one transceiver at once.
•
The computer communicates digitally with the TNC, so you can: (1)
view messages received from the transceiver or stored in a mailbox (i.e.,
PBBS), (2) use the computer to send data to, and receive data from,
other stations, via the TNC and your transceiver, and (3) control the
operation of the TNC.
