SYMBOLS.txt 7.9.7 APRS DISPLAY SYMBOLS The character after the latitude "N" in an APRS position report is a TABLE character and the character following the longitude "W" is the APRS symbol character. The TABLE character selects one of two symbol tables or may be used as a numeric overlay over some symbols as follows: TABLE RESULT / Primary symbol Table (Mostly stations) \ Alternate symbol table (Mostly Objects) 0-9 Alternate OVERLAY symbol with 0-9 overlayed A-J Alternate OVERLAY symbol with A-J overlayed (!* also) Press F1-S in APRSdos to see these symbols. The numeral "3" is overlayed on the following symbols which accept the alphanumeric OVERLAYS. THese will only show on APRS78 or later. CIRCLE, SQUARE, CAR, TRUCK, VAN, DIGIS, GATES Civil-Defense(RACES), NWS sites, WX stations, Triangle SYMBOLS WITH STAND-ALONE GPS TRACKERS: Stand-alone TNC trackers which transmit raw GPS have three alternate methods of selecting their symbol. First, by the following default SSIDs: SSID SYMBOL SSID SYMBOL ---- ------------- ---- ------------------ -0 Dot -8 Ship (power boats) -1 Ambulance -9 Car -2 Bus -10 Motorcycle -3 FireTruck -11 Balloons -4 Bike -12 Jeep -5 Yacht (sail) -13 RV -6 HELO -14 Truck -7 Aircraft -15 Van Secondly, you may indicate the desired symbol character surrounded by braces {/$} as the first 4 characters of the TNC BText. NOTE: this method works with old versions of APRS but is being phased out in future code. The disadvantage is that the symbol is not displayed until AFTER at least one BText is received. The old {$} for only the primary table was also supported. THIRD and BEST, you may now specify the symbol in the TO address of your packet using the TO CALLSIGN of GPSxyz. This is new in APRS797 and has the advantage of instant recognition on receipt. The X points to a subgrouping and the Y is the actual symbol. Z is an overlay character if used. Notice that this method results in a one-for-one correspondence for all numeric and alphabetic symbols of both upper and lower case. The symbol table has been expanded to include these XYZ letters for all symbols even though only a very small number will actually be used for GPS trackers. /$ XYZ PRIMARY SYMBOL TABLE \$ XYZ ALTERNATE WX TABLE (\) -- --- ------------------------- -- --- ---------------------- /!

You can define BOX/CIRCLE/LINE or TRIANGLE areas in all colors, either open or filled in, any size from 60 feet to 100 miles. Simply move the cursor to the location, press HOME, move the cursor to the lower right corner of the AREA and hit INPUT-ADD-OBJECTS-AREA. Enter the type of area, and color. NOTE that AREA shapes can only be defined by selecting the upper left corner first, then the lower right second. The line is an exception. It is still top to bottom, but the lower point can be to the left of the beginning point. These AREAS are useful for real-time events such as for a search-and- rescue, or adding a special ROAD or ROUTE for a special event. Be cautious in using the color fill option, since all other objects in that area that occur earlier in your PLIST will be obscured. AND you do NOT know the order of other stations P-lists. AREAS FORMAT: The new format for specifying special areas uses the CSE/SPD field to provide the additional information as follows: $CSE/SPD... Normal Field description lTyy/Cxx... Where: l (lower case L) is the symbol for "LOCATION SHAPES" T is the Type of shape: 0=circle, 1=line, 2=elipse 3=triangle 4=box add 5 to these => color-in C is the color from 0 to 15. For colors geater than 9, the / is replaced with a 1. yy is the sqroot of the latitude offset in 1/100ths xx is the sqroot of the longitude offset These offsets are ALWAYS positive to the right and down, except for the special case of a lower right quadrant line, these are given the Type of 6 and are drawn down and to the left. HURRICANES, TROPICAL STORMS and DEPRESSIONS: These symbols will be differentiated by colors red, yellos, and blue. Additionally a radius of Huricane and also Tropical storm winds will also be shown if the format detailed in WX.txt is used. SYMBOLS ON MAPS! APRS can also be permanently embedded in maps. To embed a symbol in a map, simply make the first four characters of the label be a # followed by the dual symbol character, followed by a hex number from 1 to F that indicates the color for the symbol. The remaining 8 characters can be used for a conventional label at the same location. An example are the VORTAC nav-aids in Alaska. The Anchorage VORTAC appears as ANC on all maps below 128 miles. The label entry is #\VFANC,LAT,LONG,128. SUMMARY OF ALL RECENT SYMBOLS CHANGES 1) Moved all WX symbols to ALTERNATE table but still recognize both until primary table symbol is re-used. 2) In keeping with the idea of using the primary table where possible for active stations and the alternate table for OBJECTS, I also moved the following to the alternate table (again recognizng both until the primary is re-used: ! Emergency (/! reused for police station) L Lighthouse N Navigation Buoy (/N reused for NTS station) Q Quake or bulls eye V Vortac U sunny (Sunny was $, but prefer that for ATM or BANK) l area Locations m Milepost (/m reused for Mic-Repeater)
