QK4
Remote control software for the Elecraft K4
The first fully cross-platform remote control application for the Elecraft K4. Built to bring the complete K4 operating experience — every control, meter, and display — to macOS, Windows, and Raspberry Pi. Operate your K4 from anywhere on your network, exactly as if you were sitting in front of it.
About
QK4 was created to fill a gap in the Elecraft ecosystem — a native, purpose-built remote control application that runs on any platform. No emulators, no workarounds, no compromises. Full spectrum and waterfall display, dual VFO control, audio streaming, and CW/voice operation over your local network.
