[aprssig] SKY1 - callsign?

[Al Wolfe]

    As a pilot I think that a ham using APRS in a plane is a useful tool, 
perhaps a last ditch backup to the other navaids. However, it seems that 
most of these folks include the abusive path of Wide1-n in their string. 
This path should never be used aloft. Is this the default of some of the new 
APRS-ready HTs? I saw dozens of planes leaving Oshkosh last week with 
Wide1-1 in their path. A lot of these folks did have a callsign in there 
report. And many had a KJ4 prefix which tells me they are relatively new 
hams.
