[aprssig] IGate Registering for ANSRVR (Messaging failures)(IGATES!)

Thanks so much for confirming that it is not an APRS-IS failure! I am
Now all we have to do is track down the failed IGate codes. ... A never
ending impossible search.
But lets start trying to keep a list of "broken" implementations and
"broken" settings for each software type..
I know, easy to say, frustrating and inmpossible to do...

javAPRSSrvr (internal IGate client) has always used only number of hops as
the criteria (direct is, of course, zero hops) for gating to RF. There is
no dependency on type of packet. One caveat to reduce needless gating (QRM)
to RF: when the station has been heard directly on APRS-IS (TCPIP* as path),
javAPRSSrvr will not try to gate to it on RF. Both the local and
heard-on-APRS-IS lists are timed lists. Number of hops and length of time
the lists hold their information is adjustable for local conditions.
Yes, there is some IGate software out there (I never tried to track which
software) that uses "nearby" as a criteria instead of "recently heard within
N hops". Also, remember that some people are running "receive-only" IGates
which completely break the messaging functions of APRS-IS IGates.
Receive-only IGates are at best worthless and at worst breaking messaging.
