Dave -
Thanks for opening a window into the technical world and mystery of
spotting. I back off from mystery, but radio is magic. Magic is fun. So,
who knows, you might hear me in contests from my home QTH this fall for the
first time . My call sign will never be spotted from my QTH. Just RF!!!
The radio shack is built. Now comes the tower and antenna work.....

> dynamically each time you connect there are traces and at least the ISP

> fairly easily and spot strange connections. Second are the 'telnet'
> cluster nodes. AR-Cluster, CLX, DXSpider, etc, are common software
> packages that run these nodes. These are the source of reports you may
> have seen in the past. All these node can record a log of ip addresses
> used to connect to them along with callsigns and the spots entered...
> details of how long the data is kept and the ways to save and extract it

> users to put in dx spots from a web page interface. Through various
> mechanisms these spots are then sent out onto the cluster network for
> distribution to the rest of the world.

> In the past there were several pattern based approaches to spotting self

> calls who only spotted them but no one else, and a couple other odd
