[aprssig] Spurious SSID's

[Curt, WE7U]

Even more evidence that it's happening on RF:  If you look at the
raw packets on findu for WA9RES-13/14/15, you see that multiple
igates are putting those packets onto the 'net.  It doesn't appear
to be igate software bugs in this case, but a station on RF that is
corrupting the packets.

Check for TNC's that might be in PASSALL mode.  Find out by logging
packets off RF for a while, then search for the errand callsign/SSID
combinations and check the packets immediately prior to make sure
you're pinpointing the correct culprit.

If it's a callsign substitution digi that is doing it, you might
have to send trace packets for a while in order to figure it out.
