I'll not be so kind. It was an absolutely idiotic idea.<br clear="none">

I was just about to start tracking down something I saw in my monitoring graphs when I saw this thread. It represented roughly a 1/3 increase in traffic on the APRS IS, though it seems to have stopped now. You can get a good idea of how much data he was sending before shutting it down by this page at findU, showing the last 200 packets with timestamps, he was sending dozens a second, for hours!<br clear="none">

A graph that shows what he did to the traffic volume is here<br clear="none">

This graph includes CWOP traffic, so combined the baseline represents 30 - 40,000 users, and the bump is all one selfish user.<br clear="none">

Andrew, don't ever send anything to the APRS IS that is not ham radio again. Please.<br clear="none">
