HQ2RDR
Logger & QSL Pro
A completely rebuilt desktop ham radio logger with a faster, more fluid workspace for everyday operating, DXing, activations, contests, QSL workflows, and station control.
Stable builds for Windows and Linux x64, with stable and beta update channels built into the app.
Latest version:v2.4.0
A smoother way to operate

A noticeably faster and more responsive desktop experience.
Configurable layouts for everyday, contest, and POTA/SOTA operating.
Integrated docks and workspaces that keep essential controls visible.
Improved scaling and compact-screen handling across Windows and Linux.
