AvMap APRS - Manual (Page 16)

The Geosat 6 APRS comes with an APRS bi-
directional RS-232 APRS interface compatible with
all APRS Kenwood amateur radios models and with
all the TNC (Terminal Node Controllers) that
support NMEA format sentence.
Current APRS ready Kenwood transceivers include:
TH-D7A/E •
TM-D700A/E •
TM-D710A/E •
TH-D72A/E •
Kenwood format sentence compatible radio
transceivers If the radio’s TNC supports the Kenwood
format sentence you can get the best out of your
Geosat 6 APRS: you are able to see APRS standard
icons, full tactical information for APRS contacts
such as COG, SOG, Lat-Lon, altitude, and time stamp
allowing time contact sorting.
Other NMEA sentence radio transceivers
If the radio’s TNC does not support the Kenwood
format sentence, you can see only two types of APRS
icons: a bull’s eye for fix APRS stations, and a red
triangle for moving APRS contacts. You do not get
the time stamp, so no contact time out sorting is
possible.
