Updated 28 September 2005
The symbols in this set are a composite of the original G4IDE set provided with UI-View and the U.S. customary symbols used by WinAPRS, APRSplus, the lastest version of APRSpoint, Findu, and APRSworld, etc. including the latest suggested changes by WB4APR. (The "U.S. customary" set was originally designed years ago by KH4G for use with JavAPRS and findu.com.)
Note that for web display purposes, the images are presented in GIF format. For actual use in UI-View, UI-Point and APRSplus, the images have to be in 256-color BMP format. For use by JavAPRS and Findu, they have to be 256-color PNG format.
Zip files containing this revised character set in formats ready for use with
are downloadable from links farther down this page.

A standard APRS-format position report looks like:
Choosing a character from the table above causes the symbol in the corresponding position from one of the tables below to be displayed. The cross-hair symbols occupy symbol slots that have not yet been assigned.
Primary Symbol Table - Selected by placing " / " between Lat and Long
Secondary Symbol Table - Selected by placing " \" between Lat and Long
Some of the secondary table symbols can have an alphanumeric overlay. The alternate symbols that can have an overlay are highlighted in yellow in the text grid above. The overlay character can be a single digit 0 through 9 or letter A through Z. It is placed in the position after latitude instead of " \ ".
NOTE: Many APRS applications don't properly implement the overlay technique. In such programs, you will see the base symbol from the secondary set, but not the overlaid character or digit.
This will be most obvious with new
generation digipeaters that use the solid green star in the secondary
set overlaid with a letter to indicate capability, instead of the
traditional star with fixed "D" from the primary set.
This zip file contains the revised symbol set
for the main UI-View program. These symbols are laid out in the
same 20x20-pixel-per-symbol grid used by the original symbols supplied
with UI-View, but the icons have been re-sized to 16x16 pixels which tends
to cover up less of the underlying map. Especially in crowded urban areas,
symbols overlap less and maps look better with the smaller icons.
The UI-Point add-on for UI-View allows APRS position reports to be displayed on Microsoft MapPoint 2002 or 2004. UI-Point has it's own symbol set, located in the main UI-Point program directory, completely separate from the symbols in UI-View. Normally the UI-Point symbol files are identical to the main ones in UI-View; i.e. "SYMBOLS.BMP" and "SYMBOLS2.BMP". UI-Point does not support the "MYSYMB" alternate symbol set described above for UI-View. Therefore, updating UI-Point requires overwriting the original files with like-named files. Back up the originals before unpacking the zip file below which contains files identical to the ones above, but named "SYMBOLS.BMP" and "SYMBOLS2.BMP" instead of "MYSYMB.BMP" and MYSYMB2.BMP"
NOTE: UI-Point does not properly support the overlaying of characters on top of the symbols in the secondary set the way UI-View itself does. As a result, symbols such as WIDEn-N digipeaters which should show as a WHITE letter "N" overlaid on the solid green digi star in the secondary set will appear as just the green star alone. The same issue applies to overlaid WX stations (blue circle), overlaid numbered cars, numbered boats, etc.
Updated symbols for APRS+SA a.k.a. "APRSplus".
The zip file below contains the same updated symbol set in a format compatible with APRSplus and will overwrite the original symbols. Back up the originals before unpacking the zip file.
NOTE 1: APRSplus does not properly support the overlaying of characters on top of the symbols in the secondary set. As a result, symbols such as WIDEn-N digipeaters which should show as a WHITE letter "N" overlaid on the solid green digi star in the secondary set will appear as just the green star alone. The same issue applies to overlaid WX stations (blue circle), overlaid numbered cars, numbered boats, etc.
NOTE 2: The APRSplus original symbol
set was created when far fewer symbols were "officially" defined,
especially in the secondary set. As a result, many of the symbols available for
selection were ad-hoc improvisations of the program author and would only appear
the same way on another copy of APRSplus. Some of the symbols such as the
red,white and blue USA outline, sputtering bomb and various others will no longer
The zip file below contains the same updated symbol set in the PNG format used by JavAPRS and Findu.com.
