[aprssig] Tactical call signs

[Curt, WE7U]

For what it's worth, a quick read of section 97.119 of the rules
should clarify what's required for transmitter identification:

  <http://www.arrl.org/FandES/field/regulations/news/part97/>

97.119(a), 97.119(b)(1), and 97.119(b)(3) are the relevant portions.

Looks like I could also identify my APRS or packet transmissions
using voice as well.  Again, not good practice, but legal.
