CHAT service

Built into G8BPQ's Raspberry Pi program LINBPQ is an option called LINCHAT. This is a multi-site networked round table conference program. It is sort of like IRC, Internet Relay Chat, but made for packet radio networking using the TheNET routing used by G8BPQ. Stations connect into the CHAT and whatever they type is sent back out to other connected stations with the sender's callsign.

A network of CHAT servers can be connected together via the node routing and is specified using the G8BPQ web page interface.
See Configure Chat Service

Once you are connected into a CHAT node, and presuming that other hams are connected in as well, or there is a network of CHAT nodes and multiple hams are connected, you can send text into the CHAT and it will be echoed to the other hams, and optionally back to you.
