[OZAPRS] experimenting with rural digipeater

You only need to lob your packet into the general vincinity of an iGate for
it to hit the net, the iGate itself doesn't participate in the digipeating
sequence in the normal sense.  An iGate only takes what it hears off the
channel and jams it into the APRS-IS network.   You might notice on the end
of the packet in your original email that the iGate has tacked on
"qAR,VK1KCM" this tells APRS-IS which iGate gated the packet.  You will
also notice the packet had been digi'd by VKJ2RGF & VK2RGI over-air before
being heard by VK1KCM.

For the majority of home stations WIDE2-2 is usually enough to hit an iGate
in many regions.  You might also find that in your local area there is
another alias that allows you to keep your packets contained to an area,
but this depends entirely on how the APRS digi's are configured in your
area.  Using the alias allows you to steer your packets towards an iGate,
provided there is one within your coverage area.  In Adelaide we can digi
to ADEL2-2 which is like a wide2-2 but won't escape into the mid north APRS
network, these packets from home stations are gated straight into the net
by two local iGates.

Try WIDE2-2 and watch aprs.fi to see how often your packets get into the
network.  For home stations you'd be trying to hit the APRS-IS servers
every 30mins.  See how you go.
