[aprssig] APRS for Field Day using TEMPn-N

This is a great opportunity to nail down this technology.

  > a) Set all D700's to support TEMPn-N (always)

Note that this is, as noted below, configured by the serial port and not 
from the front panel APRS menu.

How about:  BEACON VIA TEMP1-1,TEMP1-1,TEMP1-1  ??

The TEMP7-7 would only be picked up by mobiles with the permanent TEMP 
configuration.   TEMP1-1 would be picked up by all stations and since 
it's generally using callsign substitution, there will be minimal, if 
any packet pingponging.  Two, three or maybe even more hops would depend 
on circumstances.

This is a very good thing...

Folks using KPC3 and other real TNC's in their mobiles can also 
configure them as TEMPn-N systems.

This is also a good time to add "Tn-N" to the status message.

On the other hand, if you don't have access or get time to configure the 
D700 mobile on the serial port, it would be possible to add TEMP1-1 to 
the UIDIGI setting.   I just learned that UIDIGI takes 4 aliases so 
something could be setup like:  WIDE1-1,TEMP1-1,UVC,SGATE could be used.
