[aprssig] IGate Registering for ANSRVR (Messaging failures)(YAAC)

Yes, fix that!  To one hop and direct by default to define "LOCAL"..

Good point.  Yes, that is normally then going to be the same as the IGate
stations outgoing path setting.  Hopefully that defaults to 1 hop also (in
dense areas anyway).  But often is two hops in many less dense areas.

But if you are using KISS interfaces and can change the OUTOING path on the
fly, then by all means, make IS-to-RF messages default to one hop only.
WIDE1-1 for example.

Well, in some jurisdictions (the United Kingdom comes to mind), unattended
transmitters aren't allowed without special licensing. So there are some
cases where an Rx-only I-gate is better than nothing at all.

Regarding the I-gating ability of my own software, YAAC,  it looks like it
needs another update. Although it recognizes locality as being heard on RF,
it doesn't check the hop count before considering it as local (anything
heard on RF not using a third-party frame is local), and does not allow the
local user to specify any digipeat aliases for Tx-I-gated packets.

Why not configure your home station for direct-only bidirectional and then
you can support messaging instead of only sometimes being able to
communicate reliably?

Whoever came up with the "receive-only" IGate as a good thing did not think
through that APRS is a -communications- protocol, not a tracking protocol
and they did not fully understand the potential for breaking the
communication mechanisms that APRS-IS depends on.
