FdSwarm
Field Day logging for ARRL and Winter Field Day stations that need fast QSO entry and local-network synchronization without a central server.
Built for shared station logging
FdSwarm lets operators enter contacts from multiple nodes on the local network. Each node keeps working independently while sharing QSO updates with the rest of the station.
Fast QSO Entry
The logging screen is built for active exchanges, keeping the data entry workflow direct and focused.
Local Node Sync
Multiple stations can run on the same local network with QSOs synchronized across all participating nodes.
Shared-Nothing Design
Nodes can join and leave the network without relying on one central server to keep the log moving.
Start logging quickly
Open FdSwarm on each station computer, connect nodes on the local network, and keep operators focused on the exchange instead of the infrastructure.
