Connect your Morse code key to any computer for practice, training, and on-air operation with zero-delay sidetone.
The Vail Adapter operates in three distinct modes. MIDI and Keyboard modes switch automatically, while Radio mode is entered manually for on-air operation.
Configure settings and practice with vailmorse.com's built-in decoder and worldwide internet repeater.
Use with VBand, Morse Invaders, training tools, and other browser-based apps that accept keyboard input.
Key your radio directly for on-air CW operation. Works standalone or connected to a computer.
The Vail Adapter offers superior functionality over alternatives, giving you the best experience for both learning and practicing Morse code.
Choose the option that works best for you. You can build it completely from scratch or get a ready-made version.
