re-iterating that with APRS-IS dupe filtering, looking anywhere on the
APRS-IS for evidence of a particular IGate delivering a particular
station's packets is problematic. Only the FIRST IGate to gate a packet
to the APRS-IS will show in the q-Construct through all (well, most) of
APRS-IS. Due to interserver connections, different APRS-IS servers
and/or databases (like aprs.fi, findu.com, and openaprs.net) may show
different IGates for a single packet. It all depends on which IGate was
connected how when the packet was heard.
So, unless you KNOW that only a single IGate was capable of hearing a
given station, and that no digipeaters pass that packet elsewhere, it's
dangerous to assume that because that IGate didn't show on the packet as
recorded in the APRS-IS database sites means that the IGate isn't
working. It just means that another IGate was quicker at the delivery
or was better connected to the APRS-IS.

PS. That said, I've actually designed the RF to IS code path within
APRSISCE/32 to be as short as possible to avoid unnecessarily delayed
delivery of packets to the APRS-IS network.
