NWAPRS serves: Alberta, British Columbia, Northwest Territories,
Washington, Oregon, Idaho, and Montana

New info: I'm not sure where the discussion originated where someone thought the actual symbol is transmitted when an APRS station IDs itself. That is not the case. Each symbol has a alpha-numeric designation, and it is that single character transmitted in the ID packet that is decoded by the APRS software and causes that symbol to appear on the map. All APRS applications must use a similar set of characters, and the authors work together when considering new characters to the list. In any case, with the discontinued development of UI-View32 (due to the author's demise), it will become more difficult to add more symbols to the base.

You can easily configure the symbol for your APRS station or tracker by using one of three methods to establish the symbol to be used. The first is by assigning an SSID, the second by embedding characters in the BText line within squiggly brackets (no longer used), and the third by embedding the character in the SENDTO address (LTP, LOC, and Unproto) paths. The third example is the PRIMARY way to indicate your symbol on the map. I've included some of the more popular choices for the SSID and SENDTO methods. This info was derived from the APRSdos symbols.txt readme file. PLEASE NOTE THIS DOES NOT APPLY TO HOME OR OTHER FIXED STATIONS, ONLY MOBILES!

SSID	Symbol	NWAPRS Station Type
-0	Dot	Home Station
-1	Ambulance	Home PBBS (for packet)
-2	Bus
-3	Firetruck
-4	Bicycle
-5	Yacht
-6	Helicopter
-7	Aircraft	TH-D7 Station
-8	Ship
-9	Car	Primary Automobile
-10	Motorcycle
-11	Balloons
-12	Jeep
-13	RV
-14	Truck
-15	Van	TCPIP Only

I think you will find it easier though, especially if you need to routinely or quickly change the icon or symbol that appears on the map, if you simply assign the SENDTO method with the following. Replace XX OR xxx where you would normally use GPSxxx via WIDE2-2 or whatever your path:

BB	Police Car, Sheriif	LF	Fire Truck (SSID = -3)
BH	Small Aircraft (SSID = -7)	LJ	Jeep (SSID = -12)
BK	SnowMobile	LK	Truck (SSID = -14)
BP	Dot	LP	Puppy
P#	Numeral Circle (replace # with 0-9)	SJ	Steam Shovel
A#	Numbered Circle (replace # with 0-9)	LS	Ship/Power Boat (SSID + -8)
MT	Motorcycle (SSID = -10)	LU	18-Wheeler
MU	RailRoad Engine	LV	Van (SSID = -15)
MV	Car (SSID = -9)	SS#	Numbered Ship (replace # with 0-9)
PC	Canoe	SU#	Numbered Truck (replace # with 0-9)
NV#	Numbered Car (replace # with 0-9)	SV#	Numbered Van (replace # with 0-9)
PO	Balloon (SSID = -11)	LE	Horse
PR	Recreational Vehicle (SSID = -13)	LB	Bicycle
PS	Shuttle (Please don't use this unless you're NASA)	LA	Ambulance
PU	Bus (SSID = -2)	DV#	Numbered Aircraft (replace with 0-9)
PV	ATV	AS	Satellite/PacSat
PX	Helicopter (SSID = -6)	HV	Large Aircraft
PY	Sail Boat/Yacht (SSID = -5)	HS	Jogger

e.g. GPSLV V WIDE2-2 will show up as a Van on everyone's map.

e.g. GPSSJ V WIDE2-2 will show a steam shovel hauling down the road.
