Using the APRS Function
WhatistheAPRSFunction?
There is a verity of methods to display GPS position information using amateur radios. 
APRS (Automatic Packet Reporting System) uses a format that is advocated by Bob 
Bruninga WB4APR. This system performs data communications for messages and 
position information.
When an APRS signal is received from a partner station, the direction, distance, speed 
etc. of the partner station in relation to your own station will be shown in the display of 
this radio.

Using the GM Function
WhatistheGMFunction?
The GM (group monitor) function automatically checks to find if there are any stations with 
the GM function in operation on the same frequency within communication range.
The FTM-400XDR/DE can then display the position and distance and other information 
for each group member call sign on the screen.
Besides letting you know who is within your sphere of communication, this function is also 
convenient for instantly checking the relative positions of all the members in the group
Furthermore, this function can also be used to send data such as messages and images 
among the group members.

Tips
•  The GM function operates only on Band A.
•  The GM function does not work in the analog mode. When the GM function is activated, Band A will 
automatically switch to the DN mode.
•  When sending image data with the GM function in operation, the mode will automatically switch to 
the FR mode (high speed data communication mode). At the end of the data transmission, the mode 
will automatically revert to the original V/D mode (simultaneous voice/data communication mode).

(maximum of 24 stations can be displayed)
(2)  Registers the ID of partners in the group and displays only the partners
An explanation of the two methods of starting the GM operation will be given.
Refer to the separate Operating Manual GM Edition for other details on how to use the 
function (download the manual from our YAESU website).

Usingthetonesquelch
This radio is equipped with the CTCSS (Continuous Tone-coded Squelch System) which 
allows audio to be heard only when receiving signals containing the same frequency 
tone as the tone that has been set in the tone squelch menu. By matching the tone 
frequency with the partner station in advance, a quiet standby is possible.
Caution
CTCSS does not work in the digital mode. Use the   key at the beginning to switch the 
communication mode to the auto-mode select function (AMS), or to the analog mode.
Settingthetonefrequency
The tone can be selected from 50 frequencies between 67.0 Hz and 254.1 Hz.
