available in the future.
■ Packet Transfer Rate
The default APRS packet transfer rate set on the built-
in TNC is 1200 bps which is the standard among the
current APRS networks. If APRS networks which use
9600 bps transfer rate become available in the future,
select “9600 bps”

[IGNORE DCD]: DCD is ignored.
■ TX delay
This function allows you to set a transmission delay
time between transmitting the APRS data and
transmitting a flag code prior to the APRS data. When
the other station has activated their Save Mode, set a
longer delay time.
SETTING GPS PORT
