Hi,
A while ago, I asked about ways to improve my delivery of capture
satellite APRS packets. I didn't explain myself well, so I am making a
second attempt.
It is perfectly possible that I misunderstand how this should work, or
that I am doing something wrong.
I have a spare machine that has Windows and UIView installed on it and
I have been using that as an Sgate.
My Internet connection was not lost at all during this pass.
Shown below is a typical example of what I see.
UIView shows this packet (below) as gated to the Net (cut and pasted
from the "Traffic gated from RF to the Internet" window) .

I would expect my gated packet to appear on the APRS-IS at
20151101064214 (give or take a few seconds).
I would have thought it would be shown between the two records at
20151101055630
and
20151101064809
No other captured packet beat mine to the APRS-IS. In fact there are no
packets at all from ZL or VK stations who would have been in the
satellite footprint shown (none, as I write).
I looks to me as though the packet didn't make it to the APRS-IS. If any
other station also gated packets during this pass (which seems likely),
then those didn't make it either.
Is there anything I can change or alter at my end to improved the chance
of captured and gated packets making it to the APRS-IS?
