[Xastir] Xastir on pi3 with kpc3 plus

Wed Jun 28 10:39:58 PDT 2017

There are only 3 stations locally that are on the internet.  
And all the do is tx a beacon every 25 min or so  
I'm migrating to xastir from uiview. It was very easy to tell uiview to allow this internet station to gate to rf via my igate.
That's why I asked.  As of now it's working as an rx only igate and I would like to be able to allow a couple to go out on rf.

Two-way igates don't normally retransmit all internet traffic to rf.  They 
mostly only gate messages under specific circumstances (e.g. your igate heard 
the destination station as a "local" station on RF, AND did not hear the 
source station).  

It is possible to configure your igate to transmit all APRS-IS traffic from
specific stations to RF, but you should use this feature cautiously.  Mostly
Xastir's ability to do that is focused on gating weather alerts, but can
be made to transmit specific stations' posits, too.  There is no easy way to 
specify "gate all APRS-IS traffic to RF if it happens to be local."  And
Xastir doesn't have any mechanism to say "gate all APRS-IS traffic to RF" that
I'm aware of, or that I'd advertise if I knew about it.

You almost certainly don't want your Igate to transmit all APRS-IS data to RF 
unless you happen to live in an absolutely *dead* APRS RF environment.  Even
then it's ill-advised.
