Simple node access with EchoLink®memory
You can store call signs, node numbers, commands, etc. in up
to 10 DTMF memory channels dedicated to EchoLink.
And thanks to automatic call-sign/DTMF conversion, it is
easy to make use of EchoLink’s Connect by call and Query by
call. Moreover, the MCP-4A software allows you to manage
EchoLink memory.

APRS®firmware equipped as standard
Kenwood engineers working closely with Bob Bruninga
(WB4APR), who first developed APRS (Automatic Packet
Reporting System), Kenwood has developed system firmware
for the TH-D72A that enables easy APRS operation without
requiring a computer. The built-in GPS receiver provides
positional information, while weather information can be
acquired by connecting a meteorological device. All of this
information can be exchanged with other stations, and it can
also be output to a PC for map display using commercially
available APRS application software.
APRS®features that expand your enjoyment
■
Positional/directional data
With the internal NMEA 0183 compatible GPS receiver,
information is available on distance, speed and heading in

computer to input, edit and manage
data
–
for the TH-D72A’s memory
channels and APRS functions, for
example. You can also back up GPS
log data to your PC.
TravelPlus: Kenwood’s MCP-4A
software is compatible with ARRL TravelPlus for Repeaters;*
this allows data export to the
TH-D72A, making trip-planning easy.
