Kenwood has manufactured several radios, including the TM-D710 and TH-D72, that are capable of standalone operation as an APRS terminal. However, their screens are somewhat small, displaying limited information. YAAC can read the data feed from the Kenwood radio and display it with YAAC's map and tabular analysis capabilities. Unfortunately, Kenwood's firmware does not allow transmitting APRS messages from both the radio and an external computer simultaneously, so YAAC's Kenwood mode is receive-only. If you wish to transmit messages with YAAC through a Kenwood radio, you need to put the Kenwood radio's TNC in PACKET or KISS (not APRS) mode, use Serial TNC mode in YAAC, and give up the ability to use the Kenwood radio's display for tactical APRS status; note that you can use the Radio View in YAAC as a substitute for the Kenwood transceiver's APRS display.
To add a Kenwood radio, click the Add button on the Configure Ports tab. The port editing dialog will appear. Set the port type to Kenwood.
The other parameters you will need to specify for the Kenwood radio/TNC are:
COM2, etc.). On Linux, this will be a /dev/ttyS port (ex.
/dev/ttyS0) or a USB serial port (ex.,
/dev/ttyUSB0). Similar device names will be used on other Unix derivatives. Note that on Linux and Unix systems, you will need the access right to access serial ports. Typically, this will be membership in a group owning the serial ports, such as
uucp. You will also need the access right to write a lock file into the lock file directory on your system. Typically, this will be membership in the
NOTE: The Fedora Core 15 distro of Linux has a known incompatibility
with the RXTX library used by YAAC to access the serial ports, due
to moving the lock directory to a place not known to the RXTX
library. To work around this, ensure that the
directory's group is
has group write privilege, and that your account is a member of the
lock group as mentioned above.
Once you have the settings the way you want them, click OK. Ensure that the radio is connected to the port before you click OK.
