APRS-13
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
identifi cation 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 identifi cation 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 offi cial APRS website (as of October 2013):
http://www.aprs.org/symbols/symbolsX.txt
http://aprs.org/symbols/symbols-new.txt
◆ Set an icon that represents your operational status. (For example, setting
an Aircraft icon or Balloon icon to a fi xed station will cause confusion when
a station receives a beacon.)
