The RC-D710 operates as an AX.25-compliant TNC (Terminal Node Controller) for 1200/9600bps packet communications. Connecting the RC-D710 via the optional Interface Kit (PG-5J) to a transceiver adds APRS functionality, as provided by the TM-D710A FM dual bander. The RC-D710 can replace the TM-V71A control panel to enable all the features of the TM-D710A. It can also be used as the control panel for the TM-D710A.
