Hello Iain,
In both APRS and Winlink you find documentation that
associates specific SSIDs as an identifier for the station
type. In some regions similar agreements have been made
regarding the use of SSIDs as station type identifiers.
I guess that is what I am asking about.? I never seem to be able
to guess if -7 is a BBS or a CHAT or nothing-at-all.
There does not seem to be a standard in the UK???? Or am I
wrong?
In an APRS world, there are well known standards.? A good page
combining all this information can be found here:
??
In a classic packet setups, the SSID convention is very regional
specific.? In the Bay Area, California on the 145.050 frequency, we
use the following:
--
??????????? SSID :: Description
???????????
-----::--------------------------------------------
????????????? -0 :: (aka.. no SSID) direct human to human /
keyboard to keyboard chat
????????????? -1 :: PBBS mailboxes
????????????? -2 :: not specifically used
????????????? -3 :: not specifically used
????????????? -4 :: not specifically used
????????????? -5 :: netrom nodes and digipeaters
????????????? -6 :: not specifically used
????????????? -7 :: netrom nodes and digipeters (alternate)
????????????? -8 :: not specifically used
????????????? -9 :: not specifically used
???????????? -10 :: for Winlink nodes (should be
on Winlink frequencies like 145.630, etc)
???????????? -11 through -15 :: generally NEVER used since
NETROM connections will automatically use
??????????????????????????????? these high SSID numbers
starting with -15 when creating secondary
??????????????????????????????? connections.? For each hop,
netrom will continue subtracting from the
??????????????????????????????? SSID number through the
lower SSIDs to manage link by link connections
