I just don't see the problem.  If you have a car, use -9, if you
have an HT, use -7, if you are a truck driver, use -14, Use -0
(none) on your house.. Or use -10 if your house is an Igate.  If
you have a tracker, use -12.  If you have 5 trackers, use
-1,-2,-3,-4 and -12.

If y ou have more than that, use -15.  

If you have more than that, use anything you want or tactical

I don't see any confusion at all.  You can use any SSID you want
for any application you want.  It doesn't matter.  But if you
have an application that matches one of the ones on the list,
use it.

Maybe I can help, by changing the names of those 1-4 to "generic
for any application" or something like that...

They allow you to have more than one callsign on the air at the
same time.

That is done via any of the 200 symbols.

Probably an HT in the car.  Many people do that.

That is rare.  But that is his choice.  Accept it.

Yes, so it should be a -9 if it is message capable, or the new
-12 if it is a non message capable one-way tracker...
