[aprssig] RADIO paths in APRS Servers

A sad situation, but true.  And we must try to get to these
rogue sysops and see if we cannot get them to adopt the New-N
paradigm and make the APRS network work consistently everwhere..

And we need to all be vigilent and try to fix this.  This is ham
radio, where we strive to understand how our radios work. APRS
is not some kind of consumer service intentionally dumbed down
for the appliance operator.  Everyone needs to be looking at
these packets occasionally (now that they are traceable) and see
where our network needs fixing... And fix it.
