[aprssig] IGate Registering for ANSRVR (Messaging failures)

[Anthony Best]

I have heard multiple times that you should configure your home
station IGate as receive-only. However I've found that the
"receive-only" stations are often the only stations able to hear me,
the IGates on the mountain tops almost never hear my HT since they
have such wide coverage.

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.

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.
