[aprssig] Now - A New 6m tracker proposal

[Robert Bruninga]

Actually, Jim was right to bring up the 800 Lb gorrilla
in the back of the room (skywave) that would really
make a mess of a single frequency local alternate
APRS frequency.  So lets go back to the original 6m 
proposed band which was the start of this thread.

>Updated design goals for a 6m APRS black box tracker:

> * 7) Posit should be the extremely short Mic-E format
> * 8) PIC should do automatic time-slot assignment
>       (1-to-225) according to the sum of the last 3 
> *     bytes of the call plus the SSID.
* *  9) Use of time slotting avoids the need for a 
* *      CSMA receiver in the tracker.
