3. Making it all work!
a. Make sure both the Kenwood TM-D710 and AvMap Geosat 5 are turned OFF!
b. Connect the four pole 2.5mm communication cable end to the Geosat 5’s TMC receptacle and
the three pole 2.5 mm end to the D710’s GPS receptacle. IMPORTANT! These are easily reversed
and hooked up backwards…also…when connecting to the Geosat 5 make sure you plug into the
TMC receptacle…not the ANT receptacle which is right next to it and the same size! Check for a
good click into the unit.
c. NOW POWER UP BOTH UNITS!
CAUTION! If you interface the units and do not see a flashing “GPS” signal on the upper right hand
corner of the Kenwood, then the APRS cable may not be plugged-in all the way or correctly. Please
check that the cord is plugged into the proper ports and plugged-in all the way. To ensure the APRS
is plugged-in to the Geosat 5 all the way, press the cord again (may make a clicking noise 2 times).
Also verify that the Geosat 5 is receiving a GPS fix.
Once your Geosat 5 and radio are working properly together, you will see an indication on the radio
(if it provides such) that it is receiving GPS position data. In addition, as the radio provides position
information to the Geosat 5, stations will be plotted on the screen. Depending upon the location of
plotted stations, you may need to expand the scale of the map, or translate the map to a different
location in order to see them. You can also verify this in the CONTACTS folder, subfolder APRS. The
Geosat 5 will detect whether a station is moving based on the data received from that station.
If the Geosat 5 computes that a station is moving, it will be plotted as a red triangle with a call sign
label. Stationary stations are plotted as a blue circle with a call sign label. To remove all APRS marks,
enter the APRS folder you will have the option then to delete the folder. Once the folder is deleted,
all APRS marks will be removed and the folder will be gone. When the first APRS mark is created,
the Geosat 5 will create a new APRS labeled folder. To navigate to an APRS mark, select the desired
APRS mark from the list and then press GO. You will get new routing instructions from the selected
APRS mark when a new reposition packet is received.
