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....

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

Too my knowledge, that has never been the case...
There are just too many potential applications for APRS to try to force it
into just 15 SSID's, hence, since about 1995, we abandoned those defaults
for SSID-s and invented the GPSXXX format so that ANY of the over 200
symbols coiuld be used. The SSID convention never applied to anything
except for a RAW NMEA tracker, since it had no other way to inidcate its
use...
However, due to the value of at least distinguishing a mobile, an HT and
the boehemoths, I still like some of them as an easy way to recognise these
few by eye... Therefore, the only defaults that I think are of any
significance are:
>-6 is for Operations via Satellite
>-7 Kenwood D7 HH *
>-8 is for boats, sailboats and ships
>-9 is for Mobiles *
>-11 is for APRStouch-tone users (and the occasional Balloons)
>-14 is for Truckers *
With only the *'ed ones the most valid.
This does not have anything to do with color attributes which do not
distinguish by "type" but by function and other attributes...

"-8" has also been widely used for Kenwood D-700s as opposed to
"-7" for the D7s
