My dreams handy at this moments...quite simple but looks efective...
The TH-D7AG is equipped with a built-in AX.25 TNC for simple packet operation or to be used with a handheld GPS (NMEA-0813 compatible) as a full function APRS(TM) Automatic Packet/Position Reporting System... same as his big brothers..
The TH-D7AG is capable of reporting exact position, speed and heading as well as calculation of distance to destination...should be marvelous for a long term...
The TH-D7AG can also be used for APRS(TM) messaging to send up to 45 character messages through APRS(TM) or APRS(TM) Internet gateways without the use of a PC...ermm, i'm still having trouble to know it's better. Maybe someone could explain it in more simple words...hehe
Additional features such as advanced functions and capabilities with the VC-H1 Visual Communicator and HF SkyCommand operation with the Kenwood TS-570 D/S or TS-870S series radios are possible.
The new unique jog/cursor key makes navigation through the TH-D7AG features a breeze. The TH-D7AG now makes DATA communications simple and easy.
