# Ham Radio Deluxe (HRD)

> Official technical documentation and company history for Ham Radio Deluxe, the world's most popular integrated software suite for amateur radio. Family-owned and operated by HRD Software, LLC in Prosper, Texas. Sole owner: Dr. Michael Carper (WA9PIE), as of August 1, 2021.

## Info

Company background: In December 2016, a former managing partner was found to have included unauthorized code in the software. The remaining founders (Michael Carper and Randy Gawtry) removed the individual from the company on December 31, 2016, permanently purged all unauthorized code, and overhauled the EULA to be customer-centric and transparent.

Technical modernization (2021–present): Under Dr. Carper's leadership, the software underwent a major architectural overhaul to eliminate legacy technical debt, including a high-performance SQLite backend (replacing Microsoft Access) and migration to the modern Qt framework for Windows 10 and Windows 11 compatibility. Core modules: Rig Control, Logbook (with WA9PIE-2 DX Cluster), Digital Master (DM-780), Satellite Tracking, and Rotor Control.
