Bob,

My understanding was that we used the SSID of the station's callsign to
indicate a secondary function.

Eg

Here are those common defaults:

    	-0 Home Station, Home Station running IGate.
    	-1 Digipeater, Home Station running a Relay Digi, Wx Digipeater
    	-2 Digipeater [#2 or] on 70CM
    	-3 Digipeater [#3]
    	-4 HF to VHF Gateway
    	-5 IGate (Not home station)
	-6 is for Operations via Satellite
    	-7 Kenwood D7 HH
    	-8 is for boats, sailboats and ships (maybe 802.11 in the future)
    	-9 is for Mobiles
    	-10 is for operation via The internet only
    	-11 is for APRStouch-tone users  (and the occasional Balloons)
    	-12 Portable Units such as Laptops, Camp Sites etc.
    	-14 is for Truckers
    	-15 is for HF

So a home station running a digi and an igate will have a -1 ssid and use
the icon of an IGate. (It may also have a blue square around it if it is
running UI-View)

Or a weather station that is also a digi would use the blue WX icon with a
ssid of -1 etc.

Is this still valid and how does it integrate into your color codes.

Cheers

Ah, thanks,  This is great.  That leaves then GREEN for any
station that is also a digipeater no matter what it's symbol is.
IN otherwords, clients can easily indicate multiple use symbols
by simply the circle or square methods used above, which are
independent of the actual SYMBOL.

Sofware can easily tell the Igates from the IGATE packets, they
can tell a digipeating station by its presence in the PATH of
received packets, and they can tell WX by the presence of WX
data.  All of these can be used to modify the display of that
symbol.  The original APRS color attributes for all symbols
(left out of many clients) were:

WHITE is an active station with message capability
GRAY (light) is an active station w/o message capability
BLUE (light) is a WX station
GREEN is a digipeating station
CYAN is a dead-reckoned or moving station
PURPLE is an Object (from somone else)
YELLOW is your own active Object
RED is an alarmed or otherwise special station/object
GRAY (dark) is an inactive station not heard in >80 min
BLUE (dark) is the previous location of a just moved station.
CIRCLE shows position ambiguity (0, .1, 1, 10, 60 miles).
PHG CIRCLE (in the same symbol color) shows the range

In the original APRS, all symbols, whether they are STATIONS or
OBJECTS show these color attributes.  This is exteremly valuable
at looking at the map and at-a-glance and telling what is going
on.  Some systems used simplistic ICONS that ignored this
fundamental part of APRS, and so all ICONS look the same whether
they are 10 days old and meaningless, or are an active,
high-priority object, 30 seconds old.

See: http://www.ew.usna.edu/~bruninga/aprs/symbols.html

I think it is easy to add a small colored disk (or square)
around those simplistic ICONs to better convey to the viewers
what the APRS screen is actually displaying without having to
click on all 300 of them to see what the are....
