Amateur radio stations are popping up worldwide running DX Cluster software, connecting to one another via the Internet using the telnet protocol, to collect DX spots, talk messages, announcements, and mail messages. Most all have RF access (packet-radio)  for local hams while a few do not, allowing a user to connect using telnet, or HTML web-pages.
