AvMap (Written by Don Arnold, W6GPS)
The TM‑D710A/E/GA/GE uses the NMEA 0183 standard at 4800 and 9600 baud rates to communicate with the GPS
unit. The transceiver has three formats for interfacing to GPS units: NMEA, Magellan and the KENWOOD format. A
GPS system with a serial interface will connect to the TM‑D710A/E/GA/GE but if your GPS supports bi‑directional
communication, it is possible to have APRS call signs and icons appear on the GPS screen. Of all the name brand
GPS units, the AvMap G6 APRS smoothly interfaces with the KENWOOD TM‑D710A/E/GA/GE TNC better than any
other with less adaptation and more features specific to APRS and the TM-D710A/E/GA/GE by taking advantage of the
KENWOOD APRS sentence and providing a KENWOOD interface cable for truly Plug and Play operations.
Note:
◆ The baud rates refer to serial communication between transceiver and GPS and not to the AX.25 Packet communication
between transceivers.
AvMap G6 APRS has many of the normal Personal Navigator data fields that you would find in most world brand GPS
units, but AvMap developers have integrated the KENWOOD sentence format to provide you a Tactical Mode. No
other standalone GPS system has this exclusive KENWOOD/AvMap feature. If you are involved in a search and rescue
scenario, you can assign one of your APRS assets (call signs) the target designation for Tactical Mode. This designated
call sign on each position report is processed by AvMap for easy viewing and tracking.
Geosat 6 APRS provides GPS location information for your transmitted APRS beacons, and shows received APRS
information its map display.
If you are using the TM-D710A/E/GA/GE with the AvMap, in Tactical mode, you will get an additional five data fields that
can be displayed on your AvMap:
• Target ID ‑ Callsign
• Target Lat Long
• Target SOG ‑ Speed over Ground
• Target COG ‑ Course over Ground
• Target Altitude ‑ Mean ‑sea‑level
