APRS-14
APRS supports approximately 200 icons. It allows users to
select each icon by specifying a combination of two ASCII
codes, for example, ! and /. One is a symbol code, and
the other is a table identification code (either /or \). If you
select “OTHERS”, use the following procedures:
1 Rotate
the
Tuning control to select a symbol code,
then press the Tuning control.
2 Rotate
the
Tuning control to select a table
identification code, then press the Tuning control.
• Overlay Icon Setting
For example, to set the Digipeater icon to the letter “S”,
select “OTHERS” under the icon type menu, select “#”
under “SYMBOL”, then select “S” under “TABLE”.
Note:
◆
APRS icon codes (symbols/tables) are sometimes updated.
Please refer to the following official APRS website (as of April
2011):

Set an icon that represents your operational status. (For example,
setting an Aircraft icon or Balloon icon to a fixed station will cause
confusion when a station receives a beacon.)
