[OZAPRS] Re: Dupes to APRS-IS from VK5

[Larry]

Hi All

I have been away for a few days so have only just caught up.  The delay 
in packets may have been due to the fact that during the outage of the 
second.aprs.net.au at that time I was using a Florida based IS.  There 
may have also been a DCD issue at the digi that complicated matters 
also.  All is well again now that the second.aprs.net.au servers are 
back in business.

There would have been some gaps in the IS feed last week due to hardware 
upgrades being carried out at vk5ly.  This will be the case on and off 
over the next few days.

As far as support for the Scouts canoe marathon over the long weekend 
the system worked flawlessly as expected.

Cheers

Larry VK5LY
