I'm guessing that you're referring to the 'duplicate position packet'
messages? You didn't actually say what the 'strange behaviour' actually was
That would appear to be a problem upstream from .au, as it's *not* appearing
on the second.aprs.net.au data stream.. Check out
http://hamtrack.pinegap.net/stationdump.php?stationid=42434 for your raw
packet dump for the last 24 hours - you'll see that there were no duplicates
in there, so any 'duplicates' that aprs.fi may have seen, were in the global
network, not .au..

Subject: [OZAPRS] Strange APRS packets
Anyone else noticed strange behavior on the APRS system here,
Have a look at the raw packets on VK4zf-9 on aprs.fi At first I thoughht
there was something wrong with the setup in this car.
However if you look at vk4zf-7, it has the same problem.This is a completely
different car and radio.
I have noticed it also on other mobiles.
If you watch the tracks on aprs.fi the positions are all over the place.
What is going on?
