One of the purposes of packet radio to a lot of hams is the use of the DX-Cluster network. Most of the packet users do have RF access to a local cluster while a few do not. Since the internet has greatly augmented the way a DX Cluster network operates many users also access one of the numerous DX-Cluster nodes via a Telnet session.
These pages contain all known packet clusters which are linked accross the internet. In order to connect you must have a telnet application properly configured on your computer.
I have added this information to the amateur packet radio gateways pages to show the clusters on world maps, like I did with the gateways. Now you can see where the clusters are located which makes it maybe easier to chose the right one for you needs. The sources are two sites that I would like to recommend:
www.dxcluster.info and VE9DX DX Telnet Sites

Please note: These pages are completely reserved for licensed Radio Amateur Operators and show the DX-Cluster nodes which are accessible by telnet connects. Your browser must be configured to launch a telnet application to use the telnet URLs.
