Who/What is Quadnet?
From Quadnet homepage" We are an open ircDDB routing network that doesn't require registration. We contend that valid Amateur Radio license is enough to operate on the QuadNet2 USA IRC Network. We do not require a special club or repeater call sign for use on the network. As long as the call sign is valid and being legally used, we fully support your use of dongles, hotspots and repeaters (both homebrew and ICOM) on the QuadNet network. The purpose of QuadNet is to support routing. Routing is an alternate method of connecting to other D-Star users. Routing does NOT require your gateway to know the IP addresses of reflectors or repeaters to which you want to connect. You use special routing callsigns in the UR field (YOURCALL) of your radio (instead of the usual CQCQCQ) and QuadNet figures out how to get your signal to the proper destination.
